Abstract
The contrast between a target and the target markers or line divisions on a graticule disk of a sight, especially for a hand-held weapon, is enhanced by a device which illuminates the graticule disk with refected liight. The device has an attachment member which is rapidly mountable to and removable from the sight housing. The attachment member carries a frame which holds glass bodies filled with gaseous tritium and coated on the reflecting surfaces with a luminous lacquer or paint. The light entry and exit sides are not coated. The attachment member holding the frame permits shifting the frame between a first effective position in which light collected by the tritium filled glass bodies is transmitted onto the graticule disk, and a second ineffective position in which light is not transmitted to the graticule disk.
