■ All optical components are through special processing and coated with special film, formed a high-quality flat and good contrast optical images in the wide field. Especially in the peripheral visual field, it is more bright and clear.
■ Zoom objective lens 0.67X~4.5X (6.7:1), standard magnification 6.7X~45X. Use optional auxiliary lens, the magnification can be 2X~225X.
■ The standard working distance is 100mm, use optional auxiliary lens, the working distance can extend to 26mm~287mm
■ Viewing head 45°inclined, best eye-point height, correspond with ergonomic design, feel less fatigue when long time use.
■ Adopt diopter adjustment eyepiece, ensure the different vision of users to get a clear image.
■ The zoom hand wheel (axial) bilateral settings, easy operation, high precision zoom repeat.
■ Built-in wide-range voltage 110V~240V, top & bottom LED illuminator, uniform lighting and separate control.
■ Brightness is adjusted separately, it can provide long time and same color temperature lighting in whichever light intensity.
■ Stable light intensity, low voltage, low consumption, low heating value and long lifetime
