16. LORIS Monocular Night Vision System consists of a LORIS 1x observation sight with integrated battery compartment and a face mask or a helmet mount The monocular night vision system can be used by foot soldiers LORIS will make it possible to see the terrain at night and recognise a standing man at distances up to more than 200 m With LORIS near infrared light invisible to the naked eye for instance from laser pointers can be detected The sight can be used stand alone with face mask or helmet mount or mounted on a weapon with an optional weapon adapter An infrared illuminator invisible for the naked human eye built into the sight improves close distance operations such as map reading or delicate manual work while ambient light is very low or even not present A visible red warning light in the eyepiece of the sight indicates that the infrared illuminator is switched on to warn that the emitted infrared light can be detected e g by enemies with other night vision equipment An integrated light sensor switches off the system automatically if submitted to high light levels When the light returns to acceptable light levels the sight will switch on again automatically The automatic switch off feature by the light sensor can be de activated by turning the switch ring to position Il A sacrificial window can be fitted in front of the objective The window can be installed and removed without special tools A protection cap can be place
