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.
RAW format
Raw image files are unprocessed and uncompressed image data files.To convert your processed BMP into a raw file format for the purposes of compatibility, you will need to use third party software available online. One such software is available here:

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
1280 x 1024 = 1,310,720pixels / 1,000,000 = 1.3Megapixels
VGA 640 x 480
SVGA 800 x 600
XGA 1024 x 768
WXGA 1366 x 768
SXGA 1280 x 1024
UXGA 1600 x 1200
QXGA 2048 x 1538
Pixel resolution – Under VGA Model 640 x 480 image, the resolution of a single pixel can be calculated to be
1757.3 microns/640 pixels = 2.745 microns (0.002745mm) per pixel
Pixel resolution – 1.3MP – 1280 x 1024 image, the resolution of a single pixel can be calculated to be
1757.3 microns/1280 pixels = 1.37 microns (0.00137mm) per pixel

When saving images with the VGA models, you are able to achieve 300 DPI after reformatting the resolution;
For 1024 x 768 resolution can provide 2.1” x 1.6” at 300 DPI
For 1280 x 1024 resolution can provide 3.4” x 2.5” at 300 DPI
Pixel resolution – Under 640 x 480 image, the resolution of a single pixel can be calculated to be
1757.3 microns/640 pixels = 2.745 microns (0.002745mm) per pixel
Save file format allows you the option to save in 1024×768 large picture size. The JPEG format is recommended as the most common format for this but if a 100% true color match is required then you need to save in BMP or TIFF file format.
How many levels of gray could the Dino-Lite digital handheld microscopes camera see?
