I. Market Application
This infrared laser light source is specially customized for the fixed-focus infrared laser light product series. It uses a VCSEL (Vertical Cavity Surface Emitting Laser) chip with a rated power of 1W, a wavelength of 850nm, a laser beam divergence angle of 30°, and a uniform and transparent light spot, in line with FDA and IEC Class 3B laser safety level requirements, with a continuous service life of up to 5,000 hours. Used with three thousand meters of fixed-focus infrared laser light lenses, the standard lens series includes 3°, 8°, 15°, 30°, and 65°. Customers can also customize lenses with different lighting angles according to their own needs.
3KM Optoelectronics' fixed-focus infrared laser lights can be used individually or in combination. They weigh only 4 grams and are smaller than LED infrared lights. They are fully compatible with the LED infrared light product structure and do not require customers to make structural or software changes. , directly replaces LED infrared lights, with an effective light filling distance of 100-500 meters, and is used in TOF, high-end ball cameras, bullet cameras, drones and other night vision monitoring and light filling systems.

V. Notes
● The infrared laser light source belong to the class 3B 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 source is on, flammable objects are strictly prohibited within 20cm in front of the lens to prevent fires.
● The infrared laser light source 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 source 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.
