Note: there are two versions of this microscope available. Both are identical apart from model number OKN 177 ships with a premium 100W halogen illumination light (model OKN 175 has a standard 50W halogen light).
Kern's OKN microscope is ideal for all common routine inspections in the laboratory. The scope is is metallurgical; it uses reflected light from a high quality halogen light source situated above the sample.
As standard both OKN models include a large-size reflection stage which can be moved upwards and downwards. They also ship with four achromatic objectives (5x, 10x, 20x and 40x), a quintuple nosepiece (holds up to five objectives) and a complete polarisation kit.
The Kern OKN series is equipped with a binocular style eyepiece as standard. It is also possible to buy a special version of the unit with a trinocular head, allowing a digital camera to be attached to the microscope (please call if interested in this variation).
This microscope is powered by standard 230V mains connection and includes Kern's 3 year manufacturer's warranty as standard.
These specifications apply to both models (OKN 175 and OKN 177) unless stated otherwise in the table below.
