QM 100    Questar

The QM 100 combines the compactness and ease of use of the QM 1 with the relative aperture and resolution of the larger microscopes. For applications requiring high magnification and resolution, and which allow the user to work from distances
of 15 cm. to 35 cm., the QM 100 is uncontested in performance and flexibility.
