Quarton IR Dot Laser Module 940nm Class 1 1.1mW 7x21mm | Precision Beam for Stealth Sensing

• 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 1 power level, less than 1.1mW.
• 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 1 Eye-Safe, 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.
• Precision 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.

• Connect Power Supply — Ensure you have a stable external DC power supply or battery holder capable of providing between 2.6 and 6 volts. Connect the positive and negative terminals of the power source to the corresponding input points on the laser module's driver circuit.
• Integrate into System — Mount the D7xL21mm laser module securely within your device or system. Ensure the beam path is unobstructed and directed towards the intended target area for applications like positioning, measuring, or sensing.
• Activate and Test — Once powered, the module will emit an invisible 940nm infrared beam. Test its functionality by using a compatible NIR sensor or camera to confirm beam detection and alignment for your specific application, such as gesture recognition or surveillance.
