Matterhorn Brightfield / Darkfield Metallurgical Microscope

The Matterhorn microscope is a brightfield/darkfield metallurgical microscope with polarization, brightfield, darkfield and DIC. Available with reflected light only or with reflected and transmitted light. This high magnification compound materials microscope is ideal for viewing samples that will not allow light to pass through them, or samples that require darkfield or DIC to bring out relief images. Long working distance objectives allow for viewing larger samples. The trinocular microscope provides a camera port for addition of a microscopy camera.
Observation Brightfield, Darkfield, Polarization, DIC.
