808nm 200mW Infrared Laser Module, 5V Adjustable Focus, Dot / Line / Cross

Product Overview

This 808nm infrared laser module features adjustable focus, a compact aluminum housing and a manufacturer-stated optical output of 200mW. Available in dot, line or cross patterns, it is designed for integration into compatible infrared positioning, imaging and experimental research systems.

The module operates from an external 5V DC power supply and incorporates a constant-current driver. Its Ø16 × 68mm housing allows compact installation, while the included adjustable mounting bracket provides flexible positioning.

Pattern selection: Choose the dot, line or cross version required for your application. The supplied output pattern depends on the option selected.

Key Features

• 808nm infrared wavelength: For compatible infrared-sensitive cameras and detection systems.

• 200mW rated optical output: As stated by the manufacturer.

• Dot, line or cross options: Select the beam pattern suitable for your application.

• Adjustable focus: Allows adjustment of the projected pattern at the intended working distance.

• Compact aluminum housing: Ø16 × 68mm construction helps dissipate heat.

• Constant-current driver: Integrated driver circuit operates from an external 5V DC supply.

• Reverse-polarity protection: The manufacturer states that the circuit includes automatic polarity recognition and reverse-connection protection.

• Adjustable mounting bracket: Supports installation and alignment.

Applications

For integration into appropriately designed and controlled systems, including:

• Infrared camera positioning and alignment

• Machine vision and automation positioning

• Optical testing and experimental research

• Infrared line or cross reference projection

• Compatible infrared sensing and interactive detection systems

Compatibility note: Confirm that your camera or detector responds to 808nm infrared light. Performance depends on sensor sensitivity, optical filters, ambient conditions and the selected beam pattern. This module is a component and requires suitable system integration and laser safety controls.

Specifications

The following specifications are stated by the manufacturer.

Package Includes

• 1 × 808nm infrared laser module in the selected output pattern

• 1 × 5V DC power adapter

• 1 × Adjustable mounting bracket

Installation and Operating Notes

• Use the specified 5V DC supply. An incorrect supply voltage may damage the module.

• Disconnect power before wiring, installing or adjusting the mounting hardware.

• Keep the heat-dissipating housing unobstructed during operation.

• Perform focusing and alignment using suitable infrared detection equipment and controlled laser safety procedures.

• Do not assume that every camera or night vision device can detect 808nm radiation.

Laser Safety Warning

This product emits potentially hazardous infrared laser radiation. The beam may not be visible to the naked eye. A faint glow or lack of visible light does not indicate that the laser is safe or switched off.

• Never look into the laser aperture or view the beam through optical instruments.

• Avoid eye exposure to the direct beam and reflections.

• Use protective enclosures, suitable beam stops and controlled access to the operating area.

• Wear laser protective eyewear suitable for 808nm, with an optical density selected for the actual output and exposure conditions. Eyewear does not make direct viewing safe.

• Do not direct the beam toward people, animals, vehicles or aircraft.

• Keep away from children. This product is not a toy.

• For trained users integrating laser components into controlled industrial or research systems.
