TMM-746Cseries high-contrasted coaxial illumination zoom monocular video microscope systems have high-quality effect of coaxial illumination. The contrast, definition and depth of field are very good. In addition to match with coaxial illumination, also can match with LED ring illuminator. It can be used for 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 presswork’s and other plane articles with low reflectivity. TMM-746Cseries include the following models: ●TMM-746C, ●TMM-746C-D (Its shape is similar with TMM-746C), ●TMM-746C-PL, C expresses coaxial illumination. D expresses click-stop at integer magnification in zoom course. P expresses coaxial illumination with polarized module.
Main technology Specifications：
● Range of zoom objective magnification: 0.7X-4.6X, working distance73mm
