Microscope Head

The SMZ161 stereo head is an excellent choice for jewelry and gem stone inspection at an affordable price. The parfocal zoom ratio is 6:1, offering a magnification range of 7x-45x with dual-sided zoom controls and a working distance of 110mm. The head is inclined 45° and includes sliding interpupillary adjustment of 50mm-75mm.

High Eyepoint widefield 10X/F.N.20 eyepieces come standard, offering a broad field of view ranging from 30.67mm to 1.33mm. Optional eyepiece powers include 15X and 20X, for additional magnification of 67.5X and 90X respectively, without the loss of working distance. Finally, the microscope is available in binocular or trinocular format to easily capture digital images for documentation, promotion or client use. Please note that a trinocular adapter is required to fit your camera.

Illumination & Stage

Brightfield / Darkfield illumination is from powerful and consistent 6V30W variable-intensity Halogen with an aperture diaphragm adjustable from 41mm to 2mm. This allows depth of field and contrast control for easier stone identification. Incident illumination is provided by a 7-watt, 6000-degree color temp fluorescent light box on a flexible goose neck arm. The stage offers two mounting points for a gem holder and inclusion pointer along with adaptation for optional contrasting methods like immersion or polarization.

Stand

The professional gem stand features dual focus controls for precise movement through 125mm of vertical range, to accommodate different gems and stones. An integral swivel base allows 360-degree rotation and the arm inclines 45 degrees for flexible viewing positions by jeweler or client.
