Typical applications include positioning, measuring, pointing, security and surveillance, gesture recognition, consumer electronics (like smartphones and AR/VR), 3D sensing, and covert eye-safe illumination. Its invisible output is ideal for sensitive sensing and biometric systems.

Is this laser module visible to the human eye?

No, this 940nm infrared laser module emits light that is completely invisible to the human eye. This feature is beneficial for applications requiring stealth operation or minimal interference with visible light imaging systems.

What is the beam divergence of this laser module?

This laser module features a narrow beam divergence of 0.6 mRad, which allows for accurate targeting with minimal spread over distance. This precision is crucial for applications like gesture tracking and covert surveillance systems.

How long is the expected lifespan of this laser module?

The Quarton IR Dot Laser Module has a Mean Time to Failure (MTTF) of 5,000 hours when operated at 77°F (25°C), indicating a durable and reliable performance for industrial-grade use.
