Seiler Instrument offers day and night vision scopes which are primarily sold to the military, law enforcement agencies, and hunters. The VISIONMASTER® Day and Night scope is state of the art, using only the very latest in night vision technology to give the rifleman the utmost advantage in both day and night shooting situations using the same equipment.
It is no longer necessary to maintain a dedicated night vision weapon system and a dedicated day weapon system. The VISIONMASTER® scope allows a marksman to use a single weapon system 24 hours a day. To switch from day mode to night vision mode requires the operator only to disengage a spring loaded locking pin, remove the eye piece by sliding it to the rear 3/4 of an inch and sliding the night vision module onto the scope, the spring loaded locking pin engages automatically. The complete transition can be completed in no-light conditions in less than 30
Our special lens coating is designed to give optimum light transmission in the 400 to 900 nanometer wavelength (the wavelength the intensifier tubes function most efficiently in). The reticle is a triplex mil-dot ranging reticle which gives accurate ranging both day and night. The special 56 MM objective lens gives the clearest image in the lowest light of any rifle scope in the world today.
