Product Overview
Red Laser Module is a high-visibility red laser module designed for alignment,
positioning, leveling, projection and measurement applications.
With a 638nm visible red laser source and 20mW optical power,
the module provides a clear and bright red beam for a wide range of equipment integration applications.
The module can be configured as adot laser, line laser or cross-line laser.
Both spot size and line width can be externally adjusted according to the required working distance and optical configuration.
The standard module dimension isΦ12 × 50mm, making it suitable for integration into compact laser equipment and OEM systems.
The module uses a638nm red laser wavelength that provides a highly
visible red beam for alignment, positioning and projection applications.
The clear red output is suitable for applications where a visible laser reference is required.
With20mW optical power, the module provides a strong visible red output for suitable indoor and outdoor positioning applications.
Actual projection distance depends on environmental lighting, optical configuration and target conditions.
An intelligent driver board with an imported IC supports a wide range of power supply conditions.
Different operating voltage requirements can also be customized for OEM projects.
The laser module can be supplied in different optical configurations:
This makes the module suitable for different alignment and positioning systems.
For dot-type configurations, the spot size can be adjusted externally.
The supplied specification indicates an adjustable spot range from approximately:
0.4mm to several centimeters
Actual spot size depends on the optical configuration and working distance.
For line-type configurations, the line width and thickness can be adjusted externally.
The typical adjustable range is approximately:
0.4mm to several centimeters
This provides flexibility for different projection distances and equipment requirements.
The standard cylindrical module is approximately:
Diameter: Φ12mm
Length: 50mm
The compact housing allows easy integration into custom equipment and optical instruments.
The housing is manufactured from aviation aluminum with an insulating surface coating.
The internal structure includes:
The design improves heat dissipation while providing additional resistance to vibration and mechanical impact.
The module uses a new laser diode, Taiwan optical lens and intelligent driver.
Under suitable operating and thermal conditions,
the module can support extended operation, including applications requiring long operating periods.
The dot version projects a visible red laser spot for positioning, alignment and reference applications.
The spot size can be externally adjusted according to the required working distance.
The line version produces a visible red laser line for leveling, positioning and alignment.
Under suitable indoor conditions, the line projection can reach approximately8–10 meters.
The typical installation height can be approximately0–6 meters, depending on the application and optical configuration.
The cross version produces horizontal and vertical red laser lines.
Under suitable indoor conditions, the cross projection can reach approximately 8 meters,
with the horizontal and vertical lines extending approximately
8 meters according to the optical configuration and working distance.
The supplied performance specifications indicate the following approximate ranges under stated conditions.
These figures are reference values rather than guaranteed universal working distances.
Actual visibility can vary substantially according to ambient light, beam divergence,
focusing, optical design, target surface, installation height and atmospheric conditions.
The638nm 20mW Red Laser Modulecan be integrated into various industrial and commercial optical systems.
Provides a visible red reference point or line for equipment alignment.
Line and cross configurations can be used as visual leveling references.
Suitable for positioning and alignment in machinery and automated equipment.
Red laser lines can provide visual references during equipment installation and adjustment.
Dot and line projections can be integrated into measurement and inspection equipment.
The module can be integrated into customized projection systems requiring a visible red beam.
