Description: nice item removed from High School laser lab. MEASURES: TALL: 34,2mm HYPOTENUSE: 44,90 mm. CATHETUS: 31,9mm. Sent totally cleaned and in plastic bag. Ready to install and use. It was used in laser applications, but I don't know coatings. 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").
