| These are unused stock from the 70's. Hypotenuse is 69mm x 34mm. Faces are 34mm x 32mm and beveled flat 3mm to the bottom. The top (square) is 20mm x 20mm and beveled down 10mm. Might make a nice 45 degree mirror! Corresponding paperwork suggests an index of 1.625 and an abbe v. of 83.9 (phototropic glass?). Looks like these could be used to make either a porro prism or a dove prism. These may the prism blanks for a big military binocular (Big Eye?). Unused. |
