The QM1, for which Questar Corporation received an IR-100 award in 1983, was the first of a new series of long distance microscopes.

It has working range of 56 to 152 cms, a 30 to 1 variability in field of view, and remarkable depth of field, linearity and chromatic correction which make it an indispensible tool for a wide variety of laboratory and industrial applications. It has a resolution better than 3 microns at 56 cm.

The QM1 includes two selectable ports, and is compatible with standard eyepieces, 35mm, and video formats.

The QM100 combines the compactness and ease of use of the QM1 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 15cm to 35cm, the QM 100 is uncontested in performance and flexibility.

Optional extras: PowerPak 100.

The PowerPak 100 is specifically designed to increase the resolution and magnifying power of the QM100 long distance microscope.

With the addition of the package's aplanatic lens attachment, sub-micron characteristics are observable at a working distance of 10 centimetres. To overcome the limitations of CCD pixel technology or to just get a better look visually, the PowerPak 100 package also includes a Questar designed 3X magnifying lens. Fields of view ranging down to 250 microns are possible.
