Product Description

The Microtec HM-3 Gemscope has illumination specially designed for observing jewellery, such as ring mounts, engraved jewellery, cameos, watch movements and all types of gem stones.

The lighting from underneath can be general (brightfield) or directional at an oblique angle (darkfield).

The diffuse fluorescent top lighting is ideal when examining opaque objects.

The viewing microscope gives a 3D image of the item being viewed. Optional eyepieces give different magnifications and fields of view as indicated.
