Magnification: 40–800?. Abbe condenser, an iris diaphragm and light filters

Levenhuk 7S NG Microscope is an optical tool that will help a beginner biologist study the micro world and perform scientific experiments. The microscope is designed for school children and kids who are keen on biology and who are interested in the comprehensive study of the world around us. With Levenhuk 7S NG, you can study prepared microscope slides, explore one-cell protozoa, and observe transparent cuts of organic and inorganic material.

The optical elements are made of glass. The revolving nosepiece admits three objective lenses with different magnification: you can install any eyepieces with a rim diameter of 23,2 mm inside the eyepiece tube. You can adjust the sharpness with the fine and coarse focusing knobs, and move the microscope slides on the stage with an installed mechanical scale. The illumination system deserves special attention. It consists of a mirror, an Abbe condenser, an iris diaphragm and some light filters.
