2. What is a Digital Microscope?
A digital microscope is a magnifying device equipped with a digital camera. Basically, there are two types; one type is a microscope or magnifying device with a built-in digital camera while the other type is a standard style microscope adapted with a digital camera.
Dino digital microscopes function as microscope, camera, video-cam and as well as a web cam, depending on the model.

3. Should I choose a Handheld Digital Microscope or Eyepiece camera?
There are advantages and disadvantages to both types.  The handheld digital microscope with the built in camera is more portable and versatile and can provide up to a 360 degree view perspective but is usually more expensive.  Digital camera eyepieces for microscopes are generally less expensive and can be adapted for use as an accessory with any standard microscope.  Both types generally come with software which can be easily upgraded via download.  Both are self contained units and require only simple cleaning for maintenance.  Any serious repair work needs to be handled through the distributor or dealer.

If you require portability, hand-held or mounted versatility and convenience then choose one of the Dino-Lite series of digital microscopes to satisfy these requirements.  If you have an existing standard type (biological, stereo or compound) microscope and you want to convert it to a digital microscope, then you should chose a suitable “EM” or “AM” series digital camera for your microscope.

5. How to use DINO Digital Microscope?

Part A.
1. Place the illuminated specimen on the center of the microscope stage.
2. Always start observing using the lowest magnification with the microscope.
3. Aim the specimen through the objective lens.
4. Focus the microscope by slowly turning the coarse Adjustment Focus Knob, for different magnifications, until an image forms ,slowly adjust the focus back and forth to get the best focus, or to reveal hidden structure at different depths of the specimen being examined.
5. To increase magnification, rotate the magnifications or the Objective Lens depending on the models of the Microscope
6. Focusing becomes more critical when using higher magnifications as the objective lens would need to come closer to the specimen to obtain a focus.
7. Use the same techniques cautions in coarse and fine focusing as described above and use care so that the Objective Lens does not come in direct contact with the specimen when achieving a final focus.
8. CLick on “picture” button or “video” button from DinoCapture software for taking the picture you want or recording the video.
9. What are the applications for Dino digital microscopes? Industrial Inspection, Scientific, teaching tool, Skin Check, Scalp Check, Textile Inspection, Jewelry Inspection, Coin Inspection, Printing Inspection, Reading Aid, Web cam for Online chatting, and more.

Part B.
How would we know what magnification to choose for our imaging products?
Always start observing using the lowest magnification with the microscope.
Adjust the objective lens or magnification knob until the desired image comes into focus.
Then increase magnification gradually until satisfied.

To reduce glare simply change the point of view the angle of either the object or the scope by a few degrees.
On models AM311S and higher you are also able to turn off the LED lights if desired.

The TV Video models utilize NTSC analog format which provides “no-delay” images, whereas the USB models use a digital format which may cause a slight delay when focusing.

The current DinoCapture measurement functions have been tested by major LCD manufacturers to be
within a 5% margin of error under 200 x magnifications.

When examining LCD panels it may be necessary to apply a thin coat of oil (baby oil, etc) to the panel
surface in order to view sub-pixels. The “hard coating” (HC) applied to the LCD panel at the factory
may make this necessary in order to view the pixels beyond the polarize level.

Use time-lapsed capture function problem under Windows OS-
Cannot start after using time-lapsed capture function. only shows dino-lite logo and hangs there.
Possible cause: dino-lite accidentally created a corrupted .avi file from time-lapsed capture
solution: Search this particular .avi file, find and delete it.

6. How does the Focus work on a Dino-Lite Microscope -
The Dino-Lite digital microscopes are designed to achieve the specified maximum magnification and clear focus with the scope either in contact with or on the same level as the observed object or surface, such as the skin, etc.  The nozzle length is designed to provide the appropriate focal length to achieve this.  When the scope is in this optimum position then the user will be able to achieve a clear focus in two distinct magnification ranges. In order to focus in the maximum magnification range simply continue to zoom beyond the first clear focus range on the observed object or surface until you see the object again come into focus.  This second stage is the maximum magnification of the scope.   When the scope is further away from the observed object or surface you will only be able to focus in at one magnification range.

General example how the DinoLite handheld digital microscopes optics works -
The way the optics works with our scope is that there is one focus point in each distance. So farther you go the lower the magnification you can get. There is one exception at touching point where there are two focus points. One at around 50x and the other at around 200x. The device would get out of focus and into focus again from around 50x to 200x. To receive the magnification values in between, the focus point would be within the clear protective plastic lens.

7. About Dino-Lite Hardware -

- Are Dino-Lite handheld microscopes Optical or Digital Zoom?
Dino-Lite microscopes operate via optical zoom. However the standard USB AM4XX microscopes are not only optical zoom from 10X~200X but offer a supplemental digital zoom up to 330X in VGA mode. (Feature not available in AM211 or AM3XX models or on any analog/TV versions) The enhanced working distance models or "L" series i.e. AD413TL, are optical 12X~92X and offer a digital zoom up to 135X.

- What is VGA mode?
VGA (or Video Graphics Array) is the native DinoCapture window in 640x480.
As opposed to operating in Full Screen mode.

10-a. Applications for Digital Microscope and eyepiece cameras?

10-b. Applications for Digital Microscope and eyepiece cameras?
For slides, a traditional microscope would probably work better, however it would be possible to use handheld.

The Handheld microscopes offer a range of magnification of 10x-50x and also focus again at 200x. However to reach the focal points of 50x and 200x the microscope itself must be touching the object. The handheld microscope is for use for versatile movement and not particularly for slides. The 8 LED lights emanate from within the microscope downward as opposed to traditional microscopes.

11. What is the largest magnification you carry on the Digital Microscope?
The Dino Digital AM Series Handheld Microscopes offer magnification ranges from 10X to 200X.
The Dino Digital AM413 T5 Handheld Microscopes offer 500x fixed magnification.
The Dino Digital AM451 Table top Microscopes offer magnification ranges from 50X to 600X.

12. Which format should I use?
With VGA and SVGA models, the JPEG file format is easiest to save and email. JPEG also uses least amount of storage space.

Use the BMP (AM and EM series) or TIFF (EM series only) file format for better quality image when printing or publishing.

Use TIFF, PSD or EPS formats (EM series only) if CMYK true color images are required when printing or transferring images. 

- Reference of RESOULUTION VALUES –
Pixel counts can be expressed as a single number, as in a "three-megapixel" digital camera, which has a nominal three million pixels, or as a pair of numbers, as in a "640 by 480 display", which has 640 pixels from side to side and 480 from top to bottom (as in a VGA display), and therefore has a total number of 640 × 480 = 307,200 pixels or 0.3 megapixels.

A megapixel is 1 million pixels, and is a term used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays.
For example, a camera with an array of 2048×1536 sensor elements is commonly said to have "3.1 megapixels" (2048 × 1536 = 3,145,728).
Therefore: Width x Height
640 x 480 = 307,200pixels / 1,000,000 = 0.3Megapixels

13. Measurement tips -
About DinoCapture measurement feature.
The Dino-Lite Pro microscope has higher measurement accuracy at higher magnifications such as 50x or 200x. Generally you can expect up to about 4% deviation from the correct measurement results.
You can calibrate the software to acquire more accurate measurements. (Only with the measurement models of the AM4XX series).

Tips for AM413T5/AM413MT5 (500x fixed magnification) ----------
Once you have focused the image capture the desired image.
You may enter the magnification of 500 when you open the thumbnail image on the left side.
If the measurement requires even more precise and accurate figures you must calibrate the measurement first.
Focus the microscope while using a MS35B stand. Once calibrated you must not adjust the microscope knob
or else the calibration will be lost. Instead raise or adjust the microscope using the fine adjustment on the MS35B stand.

Limitations of the measurement feature:
-The measurements only can measure two dimensions (X,Y).
-There is no edge finder currently built into the program, so calibration and measurements require visual judgment.

------------------------------------------------------
The term Mil means one thousandth of an inch (0.001 inch).
A circular mil is the area of a circular wire with a diameter
of one mil, 0.001". ...
Current we can select mm = 1,000um (micrometer / microns) = 0.1 cm

mil = 0.001 inch.
inch= 1,000 mil.
um = 0.001 mm
mm = 1,000 um (micrometer / microns)

14.a. What is the purpose of LED light?
Light Emitting Diode (LED) is a semiconductor device that emits light when an electric current passes through it. LED lights are brighter in one spot while regular lights are softer.

14.b. What is the purpose of near UV LED light?
With a near UV light digital Camera you can capture very detailed data, which can be undetected by human eyes. Below are images depicting the greater detail (scratches, blemished, etc.)
that can be captured when using a UV camera versus a standard camera.

What Is Ultraviolet Light?
Ultraviolet light is part of the light spectrum, which is classified into three wavelength ranges:
UV-C from 100 nanometers to 280 nm;
UV-B from 280nm to 315 nm; and,
UV-A from 315 nm to 400nm.
These waves are invisible to the human eye, but some insects like bumblebees, can see them. The human eye responds to light with wavelengths from about 400 nm (violet) to 700 nm (red).

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest. When all the waves are seen together, they make white light.

What Is the Dino-Lite near UV series light output power (mW or mW/cm2)?
The light output power of the near UV LED for
AM413T-FVW is about 16mW x 4 LED = 64mW
AM413-FVT is about 16mW x 8 LED = 128mW
AM413-FVT2 is about 11mW x 8 LED = 88mW

The diverge angle for AM-413FVT2-- 40o

A2. Select Video setup and simply adjust the brightness using the Brightness feature.  This allows you to adjust brightness of the monitor/display only. 

A3: Turn on/off the LED’s and use external light (suggest using natural light source)

16.b. How do you get better color quality?
A: There are many different things that effect images such as lighting and the angle of your camera.
A tip on getting better image results other than using the default settings for our scopes is to adjust
the camera settings by going to Settings > Real-time image settings. From there you can adjust settings
such as white balance, exposure, and saturation.
A tip for adjusting image results for better color quality is to manually adjust the color by adjusting
the white balance and exposure to match a white surface such as white paper.

How to get accurate colors with coin or jewelry
Suggest using nature light source such as Dazor 318A3 3 Tube Desk Lamp or different backgrounds

Background for coins
* Natural light or the LED’s on the scope provide the best lighting
* For orange colored objects such as gold. A blue background would provide a good image
* For light colored objects such as silver. A black background would provide a good image
* For dark colored object such as an old dark brown coin, a white background would provide a good image

22. How can I superimpose a frame or a reticle over the real-time image or using the Crossbar

DinoCapture supports custom frames. To create your own, the image must be a bitmap, 640 x 480 pixels, and the background should be filled with solid blue (RGB = 0,0,255). This shade of blue will be ignored by DinoCapture. You can create all kinds of useful frames including reticles/crosshairs, grids, and custom shapes. Some sample frames are available for download below.
To load a frame in DinoCapture, go to Settings > Real-time Image Settings > Effects > Customized Frame, select the file and then click load frame. The frame will be superimposed over the live image and any picture captured while the frame is being used.
