TECHNICAL DETAILS The Elenek IR illuminators are built using first quality infra-red spectrum Light Emitting Diodes (LED). These diodes consist of AlGaAs-heterostructures with a thick transparent substrate and have an inverted mesa configuration with both p and n contacts located on the rear surface. They are characterized by an increased-quantum value, extra-high efficiency and extra-low thermal resistance. The diodes are of the “flip-chip” emitting element type, mounted on a silicium carrier. Contrary to the usual vertical diode type, they do not have contacts on the upper (emitting) part. Due to this fact, the diodes show a highly uniform emission, and an even, balanced beam on the lighted object. There are three types of diodes, used in the Elenek illuminators: a line up of diodes with spherical lenses single diodes with double-lens technology diodes with a parabolic lens In the medium and short range type illuminator line ups are used, assembled to units (fig.1). Each unit consists of 4 emitting elements (1), mounted on one, highly heat-conducting Silicium carrier (2), covered by a protective film of Silicium Oxide. Each diode has an individual spherical lens (3), with an emission in the requested illumination angle. A variety of lenses make the production of different angles possible. Units are mounted on an aluminum base (4), intended to conduct heat to the illuminators radiator. In the long range series illuminators, along with these 4-diode type assembly units, single diodes with double lens technology are used (fig2). An emission element (1) is mounted on a silicium carrier (2). The spherical lenses (3 and 3*) are collecting both principal and lateral illumination and forming the necessary angle. These single diodes are provided with an individual heater (4) and can be operated with high currents, resulting in great emission value levels. In the white-spectrum and the special-type illuminators (up to 300m), single diodes with double, combined type lenses are used (fig.3). the first lens (3), covering the emitting element (1), is a spherical type lens. The second lens has a parabolic shape with a 41mm diameter and a height of 50 mm. This combination makes it possible to emit all the light in the requested illumination angle. This extra high efficiency of light collecting is based on a complete internal reflection effect of the body-air border of the lens. Presently, this optical solution, with its matchless parameters, stands on the front edge of modern optic.

IR illuminators, long range IR 11M, 12M Based on the LEDs with 870nm wave length. The main difference between these illuminators is the illumination angle: 30 or 80 degrees. The IR 11M has a close range angle of 80 degrees (up to 15 meters) IR 10M Provides a possibility to visualize objects up to 200 m with high sensitivity camera’s. This illuminator also has a 80 degrees angle up to 15 meters, to spot nearby objects.
