Sight device


The invention relates to a sight device (1), in particular a reflector sight or telescopic sight, which sight device has a lighting apparatus (2) for producing or illuminating a target mark, wherein the lighting apparatus (2) comprises an light guide (3) made of photoluminescent, in particular fluorescent material and a radioluminescent light source (7) coupled to the light guide (3), wherein the light guide (3) is designed to receive ambient light and convert said ambient light into photoluminescence light along at least one segment (4) of the longitudinal extent of the light guide, and wherein the absorption spectrum (10) of the photoluminescent material of the light guide (3) and the emission spectrum (9) of the radioluminescent light source (7) in the visible range can both be characterized by a spectral bandwidth and a center wavelength. In order to increase the luminance of the lighting apparatus and thus the visibility of the target mark, the center wavelength of the emission spectrum (9) of the radioluminescent light source (7) is greater than the center wavelength of the absorption spectrum (10) of the photoluminescent material of the light guide (3)..
