7X-90X Jewelry Gem Stereo Microscope with Dual Halogen
Key Features
- 7X-90X extended zoom magnification using high-quality Greenough stereoscopic objective lenses and a 2X Barlow lens.
- Includes a specialized condenser plate for transmitted darkfield illumination -- perfect for gemology
- Super widefield optical system offering crystal clear images
- Top and bottom lights with separate dimmers
- Heavy-duty sturdy pillar stand with metal framework
- Trinocular port for adding photo or video capability
This first-class trinocular darkfield stereo zoom microscope incorporates all the most excellent features of a high quality laboratory instrument. Designed to meet the demands of modern gemology microscopy, this microscope exceeds all expectations. It comes with super widefield optics, gem clamp, and darkfield condenser with iris diaphragm. The brightfield and darkfield illumination system provides both incident (top) lighting and transmitted (bottom) lighting. The top lighting shining down onto objects is used for the observation of surface details and fine structures of jewels or gemstones. The transmitted illumination through the condenser is for the examination of inside quality of diamonds.
Optics
The stereo optics provide clear, sharp images with excellent focus-depth and a large working-distance. With 0.7X-4.5X zoom objectives, moving through the magnification range is as easy as turning a knob. 10X wide-field eyepieces provide an ample magnification range from 7X to 45X, with high-eyepoint optics to accommodate glasses or goggles. A 2X Barlow lens is included, which can be mounted to the objective housing to double the magnification range to 14X-90X. This will also result in decreased working distance. The combined magnification ranges provide 7X-90X.
