Description
The VIR-illuminator is designed for the covert illumination of the observed object in the conditions of insufficient illuminance.
The distance of the illumination is indicated for the black and white videocamera without IR correction featured with the 1/3″ matrix the sensitivity of which is no worse than 1,5•10-5 W/m² in the IR band of 0,8…1 μm (the equivalent of the videocamera with the sensitivity of 0,01 lx), the objective is F1.4. The illuminator can be installed either outdoors or indoors. During the installation it is necessary to provide free circulation of the ambient air round the case of the illuminator for cooling.

The device design
The VIR-21 series illuminator contains an IR-radiator based on luminodiodes with the built in forming optics. Constructively the illuminator consists of the case, made of aluminum alloy. On the face side of the case the luminodiodes are installed, they are covered with the light filter made of special plastic. The back side of the illuminator has radiator fins. In the back area free of the radiator fins there is a mounting hole for a standard bracket with ¼″ thread.
