Adopt the Galilean optical system.
Parallel optical zoom system, zoom body magnification range: 0.8x~5x (DVS-0850); 0.8x~6.5x (DVS-0865); 0.8x~8x (DVS-0880).
Can realize two people observe the specimen simultaneously, eliminates the defects of video teaching.
The built-in indicator system displays double color in red and green, can switch smoothly as requested, it is convenient to focus the same target.
Non-flash in focus course while from high to low magnification, large depth of field, long working distance, can be attached various accessories.
Can satisfied with demands of checking-up and analysis in fields of modern biology, medicine, environment, farming, police, micro-electronics, semiconductors, and etc.
