School microscope 600x/luster

MACHINE TRANSLATION (not authorised yet)

Precise microscope with a maximum magnification of 600x (WF 15x ocular * 40x lens). Equipped with 4x, 10x and 40x lenses screwed into a rotary (revolver) head. Below the table an adjustable flat-concave mirror (makes it independent of the electric socket). Built-in capacitor changes light rays into a focused beam, and the iris diaphragm allows to adjust the size of the light stream. Sharpness can be adjusted with 2 knobs (macro and micro): coarse and precise (with a micrometer screw). Very good quality of workmanship and image.
