Precision Adjustable Ring Light
Model R-90

The patented R-90 ring light is the first precision adjustable, 8-point ring light for stereo microscopes. It provides uniform, interference-free illumination over a wide distance range and enables users to precision adjust light output to specific applications. The R-90's "glide" system enables fast effortless adjustment to change contrast, eliminating glare without altering stereo microscope optics. Light output is brilliant and shadows are virtually eliminated.
The ring's 8-point light sources are the polished ends of optical glass fibers mounted in tilting carriers. Tilting is accomplished via a sophisticated mechanical rotating disk which uniformly directs the motion of the 8 light openings to a single convergence opint. Operating distance is 0-12". The adjustable R-90 ring light also features darkfield advantage allowing it to be used in a broad variety of scientific, industrial and commercial applications.
