Diopter sight (peep-sight)

摘要

In a known, well-tried diopter sight, the polarisation filter screens, the colour filter screen and the iris diaphragm, which are in each case accommodated in a central part, are manually adjusted by knurled discs or knurled ring and knurled screw which surround this central part. To make this adjusting process automatic, it is proposed according to the invention to use a light-dependent control circuit which carries out this adjusting operation by means of electromotive or electromagnetic drives. <IMAGE>
