Economical IR Dot Laser Module, 940nm, Class 3R, 2.5-3.5mW, with APC Driver, 2.6-6 DVC Operation Voltage, D7xL21mm, VLM-940-03 LPA, Laser Head

• Integrated Design & Industrial-Grade Performance: This 940nm infrared dot diode module features a compact, precision-engineered design that integrates high-quality aspherical plastic collimating lens, and APC (Auto-Power-Control) driver circuit. Manufactured in Taiwan, it ensures stable and consistent safe laser output at Class 3R power level, 2.5~3.5mW.
• Invisible to the Human Eye: This module emits no visible light, making it completely undetectable to the human eye. Its deep near-infrared wavelength reduces detectability by older NIR sensors and minimizes interference with ambient lighting, making it ideal for surveillance, biometric security, and sensitive sensing applications in both consumer and industrial environments.
• Compact, Class 3R, and Easy to Integrate: Measuring just D7 x L21mm (D0.276 x L0.827 inches), this 940 nm infrared module fits tight spaces and runs on 2.6~6 VDC. Eye-safe and invisible to humans, it’s ideal for consumer electronic devices, biometric systems, medical and cosmetic applications.
• Beam for Stealth Sensing: With a narrow 0.6 mRad beam divergence, this module enables accurate targeting with minimal interference. Perfect for gesture tracking, facial recognition, and covert surveillance systems.
• Durable and Economical Solution: A cost-effective solution for both consumer and industrial-grade use, this economical IR dot laser module provides reliable performance in positioning, measuring, pointing, and laser sighting. Mean Time to Failure (MTTF): 5,000 hours at 77°F (25°C).
• 940 nm Laser (Near-IR, Deep): Fully invisible to the human eye. Provides reduced interference with visible-light imaging systems and enhanced stealth operation. Typical Applications: Security and surveillance, 3D sensing, gesture recognition, consumer electronics (smartphones, AR/VR), covert eye-safe illumination.
• 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.

Economical Dot Laser Module - Low cost solution for consumer grade positioning, measuring, pointing and laser sighting device. It's also for typical applications likes optical communication, barcode scanners, CD/DVD players, spectroscopy, illumination for night vision systems, eye tracking, biometric devices and medical applications...etc.
