Nikon TS100 Inverted Microscope UV Cut Filter and  threaded adapter ring for the lamphouse. This filter protects the eyes and skin from harmful UV rays. Both filters are new "open box" however one has a slight scratch on the black metal where a dealer demonstrated how it was installed and his spanner wrench slipped. This filter will only fit the TS100 to my knowledge, THE PRICE IS FOR ONE EACH.Thanks for looking!
