Product Overview

This pack includes 5 miniature 780nm 3mW focusable infrared dot laser modules. Each module features an adjustable focusing lens, a built-in driver circuit, and red and black wire leads for integration into electronic assemblies.

Designed for a 3V DC power supply, each module has a compact brass housing measuring approximately 6mm in diameter × 10mm in length. These housing dimensions exclude the rear driver covering and connecting wires.

The adjustable lens allows the dot focus to be adapted to your working setup. Potential uses include electronic prototyping, infrared detection experiments, and laboratory optical testing, subject to verification of suitability for the intended application.

Key Features

  • 780nm near-infrared output: Infrared laser source with a dot beam pattern.
  • Specified 3mW optical output: Output specification applies to each individual module.
  • Adjustable focus: Focusing lens allows adjustment for the working setup.
  • 3V DC operation: Designed for connection to a suitable regulated DC supply.
  • Built-in driver circuit: Integrated driver supplied with each module.
  • Miniature brass housing: Approximately Ø6 × 10mm, excluding the rear driver covering and wires.
  • Red and black wire leads: Flexible leads for connection within an electronic assembly.
  • 5-piece pack: Suitable for multiple prototypes, assemblies, or replacement stock.

Adjustable Focusing Lens

The front focusing assembly allows adjustment of the dot focus for the intended setup. Final dot size depends on working distance and lens adjustment; a specific dot diameter or working distance is not specified.

Adjust the lens gently without removing the focusing assembly. Disconnect power before making mechanical adjustments, and evaluate the result using a suitable infrared viewing or detection system rather than looking into the aperture.

Power Supply and Integration

  • Use a regulated 3V DC supply.
  • Verify lead polarity before connection and disconnect power before changing wiring.
  • Do not connect directly to a 5V or 12V supply.
  • Allow for the listed operating current of each module when selecting a power supply for multiple units.
  • TTL, PWM, and analog modulation compatibility are not specified.
  • Confirm the sensitivity of your detector or camera at 780nm before selecting this module for an optical sensing project.

5 × 780nm 3mW focusable infrared dot laser modules

Each module includes a built-in driver and red and black wire leads. One purchase unit contains 5 modules.

Laser Safety

Warning: Near-infrared laser radiation. The 780nm output may appear very faint or invisible. Do not judge laser power or safety by apparent brightness.

  • Avoid direct eye exposure and viewing through optical instruments.
  • Never aim toward people, animals, vehicles, or aircraft.
  • Use appropriate beam containment and avoid reflective surfaces.
  • Select protective measures and laser eyewear according to the wavelength and assessed exposure.
  • The stated optical output alone does not establish the laser classification or compliance of the module or finished equipment.
