635nm 1mW Red Laser Module, 6×21mm Adjustable Focus Dot Laser

The635nm 1mW Red Laser Moduleis a compact red laser source designed for 

optical positioning, alignment, indication and integration into electronic or optical equipment.

With a6×21mm compact sizeandall-metal copper housing, 

the module provides a practical solution for applications where installation space is limited.

The laser produces a clearred dot or oval-shaped beam. 

For the adjustable-focus version, the front knob can be turned 

left or right to adjust the spot size according to the customer's required working distance.

Compact 6×21mm Copper Housing

The laser module uses a compact6×21mm all-metal copper casing, 

making it suitable for equipment and assemblies with limited installation space.

The brass-colored housing provides a simple and practical appearance 

while maintaining a compact cylindrical structure for easy integration.

Adjustable Focus for Different Working Distances

The adjustable-focus version features afront adjustment knob.

By turning the knob left or right, users can adjust the laser spot size according to the required working distance.

This configuration is useful when the laser module needs to be integrated into equipment with different optical or positioning requirements.

Focus Options:

  • Fixed Focus
  • Adjustable Focus
  • Customer-specified working distance

Clear Red Dot / Oval Output

The module provides a visible635nm red laser beamwith dot or oval spot output.

The output configuration can be selected according to the customer's application and required focusing distance.

Typical indoor working range isless than 50 meters, 

while actual visibility can vary depending on ambient lighting and installation conditions.

APC Circuit Control

An integratedAPC (Automatic Power Control) circuithelps maintain stable laser output during operation.

For applications requiring electronic control,

TTL customizationcan also be provided according to customer requirements.

This makes the module suitable for integration into different optical and electronic systems.
