Square spot fixed-focus infrared laser illuminator, distance of 80m
The square spot fixed-focus infrared laser illuminator features an optical output power of 4W, an 850nm wavelength, and an effective illumination distance of 80 meters. With a horizontal illumination angle of 20° and a vertical illumination angle of 4°, it boasts a continuous service life of up to 20,000 hours. Designed for integration with night vision surveillance systems such as PTZ cameras, box cameras, and UAVs, this device is specialized for foreign object detection on flat surfaces, including airport runways, roadways, and expansive open terrains.
Laser Safety Distance: ≥2.8 m
High brightness, center light intensity>450 μ W/cm2 (@ 6m)
Square light spot, larger monitoring range
I. Market Application
This product is a fixed-focus infrared laser illuminator with square spot characteristics, independently developed by 3KM Optoelectronics. Utilizing self-developed and packaged VCSEL (Vertical-Cavity Surface-Emitting Laser) chips as the light source, it is primarily designed for camera-based illumination in aviation runway monitoring, road inspection, and flat surface foreign object detection applications.

V. Notes
● The infrared laser light belong to the class 4 non-visible light laser. While the laser light is on, back-light looking at or observing laser light beam with optical instrument is strictly prohibited.
● While the infrared laser light is on, flammable objects are strictly prohibited within 50cm in front of the lens to prevent fires.
● The infrared laser light should be installed where people could not look at it directly or it should be a long enough distance from where people could look directly. Manufactures should choose the Laser radiation power according to its actual application environment, in order to avoid hurting people's eyes.
● Manufactures using our infrared laser light should put labels warning of laser radiation.
● When device fault occurs, please contact with our qualified maintenance personnel for service rather than disassemble it at your own discretion, otherwise warranty will be end of the moment you disassemble it.
