The Discovery Femto Polar biological and polarizing microscope allows you to observe samples using transmitted or reflected light at magnifications from 40x to 400x. Its achromatic optics and 10x wide-field eyepiece provide a clear image. The revolving head is tilted at 45° and rotates 360° horizontally.

The three objective lenses are 4x, 10x, and 40x, with the 40x lens protected by a spring-loaded frame. Focusing is controlled by separate coarse and fine adjustment knobs. The dual LED illumination system has adjustable brightness, with illumination above and below the stage; the diaphragm disc regulates the light passing through from below. The stage has sample-holding clips, and the body is made of metal.

The microscope comes with the 100-page, full-color book “Invisible World” in English, measuring 200 x 200 mm. It includes information about microscopy and microorganisms, as well as experiment suggestions.
