Stereomicroscope with zoom 0.67-4.5x and magnification to 135x for searching and denuding oocytes
with a working distance of up to 177 mm and interchangeable auxiliary lenses
Sunny SZN71 is a stereo microscope with continuous zoom according to Green's scheme and magnification from 3.3× to 135× due to interchangeable auxiliary lenses. Suitable for oocyte search and denudation, laminar dissection and other tasks where great depth of field and convenient working angle are important.
The main lens changes the magnification in the range of 0.67×-4.5×; three interchangeable auxiliary lenses (0.5×; 0.7×; 1.5×) expand the range and change the working distance from 47 to 177 mm. The inclined 45° bi- or trinocular nozzle with fixation and position locking is adjusted to the interpupil distance 52–76 mm. The sample clip table fixes the dishes and preparations during operation, and the switching of the image output between the eyepieces and the camera is performed by the push-pull lever.
Greene's optical scheme with a convergence angle of 10° provides a three-dimensional image; the zoom of the main lens is 0.67×-4.5×, the total magnification range with interchangeable lenses is 3.3×-135×. The working distance is 47–177 mm depending on the installed auxiliary lens (0.5×, 0.7× or 1.5×). Oculars are PL10×/22 mm, PL15×/16 mm or PL20×/12.5 mm with Diopter adjustment: 45° tilt nozzle, bi- or trinocular, interpupil distance 52-76 mm Lighting - LED, halogen or fluorescent, built-in or remote; tripod - rack, cantilever or rod. C-mount adapters 0.35×/0.5×/0.65×/1× are available for shooting.
