Description: nice item removed from High School laser lab. SPECS: TALL: 31,65mm HYPOTENUSE: 44,30 mm. CATHETUS: 31,35mm. Sent totally cleaned and in plastic bag. Ready to install and use. It was used in laser applications, but I don't know coatings. Lettering at the top says "PARSM" or "PANRSM" (not sure which). Seems uncoated, but I am not sure.
Condition: as you can see in pics, edges are in very bad shape, but if you forget about edges prism itself is very clean (no scratches or surface damage, seems "new").
Note: these items have been de-greased, cleaned, re-greased (with special oil, better than original grease) and checked for missing or damaged parts. Then tested and verified ok. Good functioning is garanteed.
