BM25B Series Biological Microscope
BM25 series microscopes are economic, practical and easy to operate. These microscopes adopt LED illumination, which save energy and have long working life, it is also very comfortable for observation. These microscopes are widely used in educational, academic, agricultural and study field. With a microscope adaptor, a digital camera (or digital eyepiece) can be plug into the trinocular tube or the eyepiece tube. Built-in rechargeable battery is optional for outdoors operation or places that power supply is not stable.
+ New machining facility and advanced alignment technology
+ Complete functions and outfit of binocular microscope
+ Comfortable operation with updated and ergonomic design
Bright Field Observation
New achromatic objective supply the sharp image after adjusting Iris diaphragm. You can get high resolution and contrast ratio image at low or high magnification. 1W Single LED illuminator supplies bright background. (Plan Achromatic Objectives are optional）
High-powered single LED cold light illuminator
It maintains constant color temperature and closes to sun light. It can apply bright white back-ground. The illuminator supplies stable brightness and temperature difference never occurred even long time worked. Comparing with halogen lamp, LED has lower power dissipation.Brightness is adjustable freely by the rotatable key at lower left side.
Seidentopf Binocular Head, Inclined at 30°, Interpupillary distance is adjustable from 55mm to 75mm. The right eyepiece tube is ±5 diopter adjustable.
