Fiber Optic Light Ring for Microscope Illuminator Approximately 36" Long
I hooked it up to a light source and it works great. I only have the accuracy of a measuring tape but the diameter of the end looks to me to be about 5/8" in diameter. The ring is about 3-5/8" OD while the next step down from that is about 2-5/8" ID and the center ID is about 2". The length of the cable looks to me to be about 36" not including the ring. The tightening bolt for the ring is missing.
