| This is a rare prism in that the image viewed thru the prism is rotated 180 degrees. It inverts and reverts. If you want to look at the sky, you look straight down towards the ground! Prism is 3-1/4" long by 5/8" wide. Unused in original packaging. Not sure what optical device this was intended for. Clearly a quality piece. Original Govt. cost was $672.52. |
