Economical IR Dot Laser Module, 850nm, Class 3R, Less Than 5mW, with APC Driver, 2.6~6V Operation Voltage, D7x21mm, VLM-850-03 LPA, Laser Head

• Integrated Design & Industrial-Grade Performance: The VLM-850-03 LPA infrared dot laser module integrates a laser diode, aspherical collimating lens, and APC (Auto-Power-Control) driver circuit in a compact precision design. Made in Taiwan, it delivers stable, Class 3R output (2.5~3.5mW) with reliable industrial-grade performance and durability.
• Invisible 850nm Beam for Specialized Applications: Operating at 850nm near-infrared wavelength, the module emits an invisible IR beam detectable by IR sensors and cameras, but not human eyes. Ideal for night vision illumination, eye tracking, industrial sensing, biometric, and medical applications requiring invisible, accurate illumination.
• Compact Design with Flexible Integration: With D7 × L21mm (D0.276 × L0.827 inches) size and 2.6–6VDC operating range, the VLM-850-03 LPA offers easy system integration. Its small form and APC driver ensure stable output, suitable for consumer and professional devices.
• Beam for Accurate Targeting: featuring a tight beam divergence of 0.6 mRad, this module delivers a focused output for precise alignment and measurement. Ideal for LiDAR, robotics, and*sensor calibration, ensuring dependable accuracy across industrial applications.
• Durable and Cost-Effective IR Laser Solution: An economical yet industrial-grade IR laser, the VLM-850-03 LPA ensures reliable use for positioning, measuring, and sighting. With a Mean Time to Failure (MTTF) of 5,000 hours at 77°F (25°C), it combines durability, efficiency, and value.
• Notice: Our laser modules are NOT laser pens and are NOT intended for general commercial or consumer use like standard laser pointer. They feature NO built-in switch or battery compartment and must be operated with an external power supply or battery holder.
