I. Market Application
2.5° Fixed-Focus Infrared Laser Light
Utilizing VCSEL laser chips as the light source, this product features a 4W output power and 850nm wavelength, with a compact weight of 110g. It achieves an effective illumination distance of 800m, producing a 36m diameter light spot at 800 meters. Key advantages include:
Low wavelength temperature sensitivity (~0.06nm/°C).
Microlens technology ensures excellent light transmission and uniformity, with no stripes, speckle, or dark spots in the light pattern.
Continuous service life of up to 20000 hours.
Supports single-unit or modular configurations for high-end night vision surveillance systems in dome cameras, bullet cameras, drones, and other applications.

V. Notes
● The infrared laser light 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 is on, flammable objects are strictly prohibited within 20cm 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.
