The LED-RP is a transmitted light-source for stereo microscopes, handheld microscopes, or any other application that could benefit from pass-through lighting. The 95mm circular plate provides a 72mm-diameter, diffused lighted-surface with 6W of LED illumination. The wired remote-control allows you to adjust the brightness as needed. This adds the ability to view specimen-slides, gemstones, and other translucent objects. The LED-RP is a perfect companion to USB handheld microscopes and stereo microscopes.
