635nm 650nm 639nm Red Laser Positioning Module

TheRed Laser Positioning Moduleis a compact laser head designed for industrial positioning, 

alignment, optical indication and equipment integration.

Available in635nm, 639nm and 650nm, the module provides a clear and bright red laser 

output while maintaining a soft visual appearance for practical positioning applications.

The module can be configured as aspot or line laser, 

with external adjustment available for applications requiring flexible beam size or line width.

Adjustable Laser Spot

For spot-type configurations, the laser spot size can be externally adjusted according to the application requirements.

The adjustable spot range can be configured from approximately

0.4mm to several centimeters, depending on the optical design and working distance.

This makes the module suitable for:

• Position marking
• Alignment
• Optical indication
• Machine positioning
• Industrial equipment
• Measurement systems
• Machine vision applications

Adjustable Red Laser Line

For line-type configurations, both theline width and line thicknesscan be adjusted externally.

The adjustable line width can range from approximately0.4mm to several centimeters, 

depending on the selected optical configuration and projection distance.

The clear red laser line can be used for:

• Industrial alignment
• Machine positioning
• Cutting alignment
• Equipment calibration
• Optical reference lines
• Inspection systems
• Manufacturing equipment

Clear and Comfortable Red Laser Output

The optimized optical design provides aclear and bright red laser outputwhile maintaining a relatively soft visual appearance.

Different wavelength options, including635nm, 639nm and 650nm, can be selected according to the customer's application requirements.

Intelligent Driver Board

The laser module uses anintelligent driver board with an imported IC, providing stable electrical control and supporting a wide input-voltage range.

The standard power supply range is3.5–25V, while other voltage configurations can be customized according to the customer's equipment.

Durable Aluminum Housing

The laser head uses anaviation aluminum housing with insulating surface treatment.

A built-in heat sink, thermal silicone and AB adhesive are used to improve heat dissipation and mechanical stability.

The internal structure is designed to provide:

• Efficient heat dissipation
• Stable laser operation
• Shock resistance
• Drop resistance
• Improved mechanical protection
• Long-term operating stability

Designed for Continuous Operation

The module uses a new laser diode core and Taiwan optical lens. 

With proper electrical and thermal conditions, the module is designed for

continuous industrial operation, including applications requiring extended daily operating hours.

Actual lifetime and operating performance depend on wavelength, 

output power, operating voltage, ambient temperature and thermal management.
