Light Logics develops holographic weapon sight elements for defence

Light Logics, a Trivandrum Technopark-based company has developed professional grade holographic weapon sight elements, for the first time in India. Light Logics is a techno-intensive company with core capabilities in Holographic Imaging and Photonics.

Holographic sights facilitate sharp, quick and easy aiming of weapons. The development is a shot in the arm of the company that has been recently adjourned by the ISBA (Indian Science Technology and Entrepreneurs Parks and Business Incubators Association) as the most innovative Indian Engineering and Production Company incubated under the various technology parks of the country. The company is supported by the DSIR (Department of Scientific and Industrial Research). Dr Ajith Kumar, CEO of Light Logics said that the production of professional grade holographic weapon sight elements is a great step forward and a scientific development of national importance that will help the country in its defence and the onsite operations against terrorists.

Usually a weapon is aimed with the help of a few reference points on it and it is brought in line with the target and fired. In laser sights, a laser beam is emitted from the weapon and the beam spot of this laser, falling on the target is used to align the weapon with the target and fire. Since the laser spot falling on the target is really tiny, here alignment with the target is difficult when the target is away from the weapon.

Here it is essential to send a laser beam to the target, and hence the target recognizes that he is targeted. Holographic sights carry a set of critical light diffracting element that creates a virtual spot that is used to target the weapon. It has wider field of view and hence very easy to align the weapon, even if the target is moving. If the focal distance of the virtual spot is 25 meters, it is as good as having a weapon of 25 meters length that virtually touches a target at 25 meters way and fires, he added.

Holographic elements of weapon sights have to meet stringent and stable performance parameters. Also, such holograms have to undergo testing environmental stress and temperature conditions. The elements have to maintain its accuracy and clear vision repeated exposure to under ultraviolet radiation. Light Logics sight element qualifies on all such aspects and is one of best sight elements now available in the world.
