This is heavily dependent on the performance of your night vision device, its magnification, the setting of the light cone and the wavelength. A higher magnification of the night vision device automatically means a smaller field of view. The light cone of the laser can now be adjusted in a more focused manner, thus increasing the luminance and the range. Depending on the night vision device, magnification and wavelength of the Laserluchs, the range can be up to 800 meters . We will be happy to advise you on the selection of a Laserluchs illuminator that is optimal for you.
