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 **Industrial Precision from Taiwan** — The Quarton VLM-780-03 LPT laser module is engineered in Taiwan for industrial-grade performance. Its 780nm near-IR output, largely invisible but glowing faintly in darkness, offers discreet targeting. Unlike local alternatives that may lack precise wavelength control or safety certifications, this module provides a stable, Class 1 eye-safe output (<0.7 mW) with an APC driver. This ensures reliability for critical applications in optical communications, barcode scanning, and scientific analysis, making it a superior choice for demanding tasks. **Ideal for Specific Industrial Needs** — This module is best suited for industrial, scientific, or specialized electronic applications requiring a discreet 780nm NIR laser. It is NOT a consumer laser pointer and requires an external power supply. Those seeking a visible laser pointer, a product with a built-in switch, or a device for general consumer use should look elsewhere. It is also not intended for direct medical treatment applications, though it can be used in diagnostic imaging. ## How to use 1. Ensure you have a stable DC power source providing between 2.6 and 6 Volts. Connect the positive and negative terminals of your power supply to the corresponding input points on the laser module. — Connect Power Supply 2. Mount the compact D7xL21mm laser module within your device or setup. Its small size and precise beam are ideal for integration into optical communication systems, diagnostic equipment, or sensing applications. — Integrate into System 3. Once powered, the laser will emit a near-infrared beam. Test its functionality and targeting accuracy in your specific application, ensuring it operates within the intended low-light or discreet environments. — Activate and Test ## Product details | Field | Value | |---|---| | Laser Wavelength | 780 nm | | Laser Output Power | <0.7 mW | | Beam Divergence | 0.6 mRad (full angle) | | Power Source Type | DC | | Operation Voltage | 2.6–6 VDC | | Driver Type | APC (Automatic Power Control) | | Lens Type | Aspherical Plastic Collimating Lens | | Light Source Type | Laser | | Number of Light Sources | 1 | | Batteries Included | No | | Batteries Required | No | | Intended Use | Industrial, scientific, optical communications, barcode scanners, spectroscopy, medical diagnostics | | Not Intended For | Laser pens, general consumer use, devices with built-in switch/battery | | Mean Time to Failure (MTTF) | 5,000 hours at 25°C | | Eye Safety Certification | Class 1 | | Brand | Quarton | | Model Name | VLM-780-03 LPT | | Item Type Keyword | Diode Lasers | | Material | Metal | | Color | Silver | | Finish Type | Unfinished | | Item Shape | Cylindrical | | Country of Origin | Made in Taiwan | | Item Weight | 5 grams | | Package Weight | 18 grams | | Package Dimensions | 11 x 1 x 14 cm | | Item Dimensions | D7 x L21 mm | ## Frequently asked questions ### Is this Quarton IR Dot Laser Module safe for eyes? Yes, the Quarton VLM-780-03 LPT is a Class 1 eye-safe laser module, meaning its output is below the threshold that could cause harm under normal operating conditions. It is designed for industrial and scientific use where safety protocols are followed. ### What is the best use for this 780nm IR laser module in India?
