Division “LAIR” of the Ruđer Bošković Institute is a R&D organization specialized for research and development in the field of military photonics. The division can independently, in the scientific surrounding of Ruđer Bošković Institute, work on the R&D of sophisticated instrumentation for military purposes.
In the frames of the division there are some development groups and laboratories, i.e. Laboratory of optical instrumentation, Laboratory of thin films, Laboratory of optoelectronics, Laboratory of photolithography, Group for electronic support, mechanical and optical workshop and, finally, Quality control. In the cooperation with several companies we cover the full cycle from the basic idea and development of the functional model, until the small series production.

Product Examples
PC-1 Panoramic telescope is the aiming device for guns and howitzers.
K-1H Collimator with tripod is used for determination of the aiming point for guns and howitzers, for orientation of the weapon and topographic artillery application.
CN-4 Optical mortar sight is the aiming device for mortars and rocket launchers.
CN-5 Aiming telescope for recoilless gun BT82
The reticle can be changed in accordance with the desired ballistics and desired external configuration for the use on similar systems.
Night sight – NC-2
NC-2 is a highly efficient multipurpose night sight with an image intensifier of the generation II. Thanks to its large objective diameter the night sight has superior properties in comparison to other night sights available on the market. NC-2 can be used in numerous infantry, artillery and marine applications. The intensifier has automatic gain control and automatic overexposure protection.
Boresights DR-40, DR-30 and DR-20
The boresight is being used for fast and efficient check and adjustment of the rectification of the 20-40 mm guns. It consists of the elbow telescope and gauges for 40, 30 and 20 mm. The gauge can be adapted for any other diameter, i.e. type of weapon.
Boresight DR-125
The boresight is being used for fast and efficient check and adjustment of the rectification of the M84A’s gun. It consists of the elbow telescope and the gauge for 125 mm. The boresight can be used for other guns of the same diameter. The gauge can be adapted for any other diameter, i.e. type of weapon.
REMOTE LASER MINE ACTIVATORS LAM-1 AND LAM-2
Principle of operation:
The invisible laser beam is used to remotely activate mines or mine fields. The system consists of the laser transmitter and four receivers. The laser transmitter irradiates a digitally modulated beam. Four different codes of beam modulation are available. For each of the codes there exists a receiver as a part of the set. That enables activation of various receivers that are all in the same laser beam. Receivers are wire-connected with mines.
