The Grino optical system, with a 10° body-view convergence angle and large field of view flat-field eyepieces, ensures the flat-field nature of the image at a large depth of field.

Innovative push-pull 3-way switching lever, fixed frame and fixed multiplier mechanism and multiplier limit function design further ease the user's fatigue brought about by prolonged operation, in line with the principle of ergonomics.

The same magnification can be accurately repetitive positioning, a good solution to the problem of magnification calculation when observing objects. The handwheel is light and comfortable, effectively avoiding the fatigue caused by long time operation.

The SZN71 Digital model has a simplified design that eliminates complex wiring harnesses and has a built-in integrated digital viewing head. Images under the microscope can be output to the display in real time via WIFI HD, and can also be transmitted to external tablets and cell phones via wireless network, realizing simultaneous preview and observation by multiple clients. Compatible with IOS, Android, Windows and other mobile devices. Built-in SOPTOP Mvimage professional digital image analysis and processing software, realizing image preview, photography, measurement, image adjustment and other functions.

The magnification can be expanded from 2X to 180X, and the maximum distance can be up to about 280mm, which can provide you with clear and bright observation images under any magnification, and is suitable for observing a wide variety of objects, and can also satisfy different observation purposes.
