GL-99T Stereo Microscopes
The high performance GL Series stereo microscopes utilize a Greenough design and feature a 1:7 zoom ratio with a 103mm working distance and a large visual field. Their parfocality allows an erect image of the observed specimens to stay in focus through repeated changes in the magnification. They feature a guidepost structure, making them lightweight, and a pair of horizontal magnification changing knobs to maximize comfort. Adding to the ergonomics is a choice of observation angle, either 45 or 60 degrees. In addition to performance and comfort, a highlight of the GL is their durability. Promoting one of the finest ball bearing guideways in the world, the focusing mechanism is extremely robust.
