Microscope B-65 Monocular Brightfield
The OPTIKA B-65 is an educational biological microscope for brightfield observation. It has a monocular head inclined at 45° that rotates 360°, a WF10x/18 mm eyepiece secured by a screw, and four achromatic objectives (4x, 10x, 40x and 100x oil) with anti-fungus treatment, giving magnifications from 40x to 1000x. The StagErase™ mechanical stage measures 125 x 125 mm with a 62 x 24 mm X-Y range and a vernier scale, and scratches on its surface can be erased. Focusing is coaxial coarse and fine with a limit stop to prevent contact with slides, and an Abbe N.A. 1.25 condenser with iris diaphragm is pre-centered and focusable. Illumination is a 1 W LED with brightness control, powered by rechargeable batteries or a multi-plug external power supply, so it can be used without a fixed power outlet in school labs.
