Optical system of SZM series zoom stereo microscopes is newly, fully coated optical system sharp and clear images with extremely good flatness and contrast. The images are brighter and more distinct even as the periphery of the field of view. With their large zoom range and long-working distance, these are ideal for high-magnification, high-resolution observation in biological research, precision-oriented semi-conductor and other industries.

§ Viewing head: 45° inclined, 360° rotatable binocular head or trinocular

head. The inter-pupillary distance adjustable between 54-75mm; both

diopter adjustment of range ±5mm.

§ Eyepiece: Wide field, high-eyepoint eyepice, It can observe image of

observation specimen with glasses.

§  Objective: Zoom objective magnification 0.70X-4.5X.

§ Magnification range: between 3.5X-180X.

§ Working distrance: 100mm, special maximum working distance can provide

more working space for you

§ Illumination: Built-in and built-out illumination system.

§  Accessories: There are many accessories to choose.
