Collimator gunsight |
摘要 |
A collimator gun sight is formed of a solid block of glass with plane parallel opposite end faces. A partially reflecting concave surface in the block forms an image at infinity of a graticule pattern which is illuminated by light entering the block through a window. The block is made from a rod with plane end faces and a lens doublet element cemented to one face.
