FIELD: photography.
SUBSTANCE: photosensitive device is made such that reflected light of detection light emitted outside from housing 1 of device by one or more light-emitting elements 2, arranged in said housing 1, is detected by light-receiving element 4, installed on mounting panel 3, wherein said reflected light is reflected from a detection region, located outside housing 1 of device. Passage space for reflected light inside housing 1 of device is separated from other space in housing 1 using separating element 6, located on mounting panel 3, so that between mounting panel 3 and separating element 6 there is seal 5, surrounding light-receiving element 4 and made from elastic material. Separating element 6 has clamping wall 7 configured to come into clamping contact with outer peripheral wall of seal ring 5, when separating element 6 is installed on mounting panel 3, thereby providing application of clamping contact force to ring seal 5 with distribution of clamping contact force in direction of radial compression, wherein clamping contact force is force with which ring seal 5 comes in contact with mounting panel 3.
EFFECT: invention enables to design a photosensitive device, whose structure is simple and does not reduce detection accuracy.
