SZDB1175 series high-contrasted coaxial illumination zoom microscopes
Brief Introductions:
SZDB1175 series high-contrasted coaxial illumination zoom microscopes have two types, SZDB1175BTC (trinocular) and SZDB1175BC (binocular). They have high-quality effect of coaxial illumination. The contrast and definition are very good. We can carry on video displaying and binocular eyepieces observing at the same time. The image is erecting by eyepieces observing. Choosing to buy relevant adapters, it can connect CCD (or CMOS) camera, digital camera or film camera. It can be used in observing and measuring reflecting objects. Specially fit for checking-up the underside of the small deep hole, the bug of LCD, checking-up and measuring plane press works and other plane articles with low reflectivity.

Note: a. Total magnification=Eyepieces magnification × Zoom body magnification For example: Matching 10X eyepieces, on zoom body's scale locating 3, Total magnification=10 × 3 =30X b. Field of video = The diameter of field of eyepieces ÷ Zoom body magnification For example: Matching 10X eyepieces, on zoom body’s scale locating 3, Field of video =22÷3=Φ7.33mm | ||||||

Note: a. Field of video is based on 1/3" CCD camera. b. Video magnification=Total optical magnification × Digital magnification Total optical magnification=CCD adapter magnification × Zoom body magnification For example: CCD adapter is 1X, on zoom body's scale locating 2, Total optical magnification=1×2=2X Digital magnification = The size of display screen diagonal ÷ The size of CCD camera plate diagonal The size of CCD camera plate diagonal: 1/3" CCD: 6mm; 1/2" CCD: 8mm; 2/3" CCD: 11mm. For example: 14" monitor matches 1/3" CCD camera's digital magnification=14×25.4÷6=59.27 17" monitor matches 1/3" CCD camera's digital magnification=17×25.4÷6=71.97 |
