Sight |
摘要 |
A sight apparatus has a day-sight part, a night-sight part and a filter which quenches the visible light so that the night-sight part in the form of an IR sight can be used during the daytime as well. In order to improve use of the night-sight under daylight conditions the filter has characteristics which quench visible light having wavelengths outside the wavelengths of blue light and is arranged in the beam path for the incoming visible light.
