They feature NO built-in switch or battery compartment and must be operated with an external power supply or battery holder. ## Why choose this product **Engineered for Precision & Stealth** — This Quarton IR Dot Laser Module is engineered for applications where invisible, precise light is critical. Its 940nm wavelength and narrow beam divergence ensure accurate targeting without visible detection, ideal for covert surveillance and advanced sensing. Unlike generic lasers, it features an APC driver for stable output and an aspherical lens for superior beam quality. Manufactured in Taiwan, it meets industrial-grade standards for reliability. For Indian users, this offers a specialized component for sophisticated projects, ensuring performance where standard lasers fall short. **Ideal for Specific Industrial & Security Use** — This module is best suited for industrial positioning, security systems, gesture recognition, and biometric applications where invisible IR light is required. It is NOT a laser pointer and requires an external power supply and integration into a larger system. Users seeking visible light lasers, simple pointer functionality, or products with built-in batteries should consider alternatives. This is a component for technical integration, not a standalone consumer device. ## How to use 1. 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. — Connect Power Supply 2. 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. — Integrate into System 3. 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. — Activate and Test ## Product details | Field | Value | |---|---| | Laser Wavelength | 940nm (Near-Infrared) | | Laser Class | Class 1 | | Power Output | Less than 1.1 mW | | Beam Divergence | 0.6 mRad | | Driver Circuit | APC (Auto-Power-Control) | | Lens Type | Aspherical Plastic Collimating Lens | | Operation Voltage | 2.6–6 VDC | | Power Source | External power supply or battery holder required | | Included Components | Laser module | | Mean Time to Failure (MTTF) | 5,000 hours at 25°C | | Typical Applications | Positioning, measuring, pointing, security, surveillance, gesture recognition, consumer electronics, biometric systems, 3D sensing, covert illumination | | Cost per use | N/A (Component, not consumable) | | Brand | Quarton | | Model Name | VLM-940-03 LPO | | Part Number | VLM-940-03 LPO | | Color | Silver | | Material | Plastic | | Dimensions (Module) | D7 x L21mm (0.276 x 0.827 inches) | | Item Package Weight | 18 grams | | Country of Origin | Made in Taiwan | ## Frequently asked questions ### Is this Quarton IR Dot Laser Module safe for eyes?
