The650nm 5mW Adjustable-Focus 3-Pin Red Dot Laser Moduleis a compact visible red semiconductor laser source designed for precision positioning, alignment, indication and OEM equipment integration.
Featuring a miniatureØ6×10mm aviation aluminum housing, adjustable focusing structure and 3-pin through-hole configuration, the module provides a clear red laser dot with low power consumption and compact mechanical dimensions.
The standard version operates at650nm ±10nmwith output power below5mW. This module is suppliedwithout an integrated driver board, so a suitable external driver circuit is required for proper operation.

The module generates a visible 650nm red laser dot suitable for compact optical positioning and indication systems.
Typical optical characteristics include:
The focus can be optimized according to the required working distance to improve spot size and projection clarity.
Actual visibility and effective working distance depend on ambient lighting, target reflectivity and focusing conditions.
The standard configuration uses an adjustable focusing structure.
Users can optimize:
A fixed-focus configuration can also be supplied for applications requiring a predetermined working distance.
The module uses a compact3-pin through-hole configuration, making it suitable for PCB-based integration and miniature electronic products.
Benefits include:
This model doesnotinclude an integrated driver circuit.
A suitable external laser driver should be used to provide stable current and protect the laser diode.
Typical electrical parameters:
A matching driver board can be provided separately if required.
The module uses an aviation aluminum all-metal housing with a compact size of:
Ø6×10mm
Advantages include:
The standard 5mW version is specified asClass IIIA.
Avoid direct eye exposure to the laser beam. Appropriate laser safety measures should be incorporated into the finished product according to the selected output power and applicable regulations.
