Designed for professional optical research and controlled engineering applications, this 120W 915nm laser system combines a Raycus laser source with a large 50× manually adjustable focusing assembly.
The optical configuration supports working distances from approximately 1 meter up to 20 meters under suitable conditions, providing greater focusing flexibility than standard compact laser systems.
A rechargeable battery system, coaxial red alignment beam and integrated thermal protection are incorporated into the portable cylindrical platform, making the system suitable for laboratories, engineering teams and professional research projects requiring a self-contained infrared laser source.
The system is built around a Raycus laser source with approximately 125W rated pump power and approximately 120W optical output.
Operating at 915nm, the primary near-infrared output provides a high-power optical platform for controlled research, engineering evaluation and specialized professional testing.
Electrical power consumption is approximately 240W.
The 50× focusing assembly is one of the defining features of this model.
A threaded rotary focusing mechanism allows trained operators to manually adjust the optical configuration according to the required working distance.
This provides greater flexibility for professional projects where the same laser system may need to be configured for different test distances.
Whenever the working distance changes, the optical focus should be readjusted.
Without the focusing lens, the system is primarily intended for shorter-distance setups of approximately 1 meter.
With the 50× focusing optics correctly adjusted, the recommended working range can extend from approximately 1 to 20 meters under suitable conditions.
Actual usable distance depends on:
Focus accuracy
Mounting stability
Atmospheric visibility
Battery condition
Optical alignment
Environmental conditions
For longer-distance applications, stable mounting becomes increasingly important.
For applications beyond approximately 8–10 meters, the system should be installed on a tripod, gimbal or other stable mounting platform.
At longer distances, even small movements of the main unit can produce significant changes in optical positioning.
A stable mounting system helps improve alignment repeatability and focus adjustment during controlled testing.
Because the primary 915nm output is not safely visible to the human eye, the system incorporates a visible red alignment beam positioned along the optical axis.
The red reference provides a convenient visual aid during preliminary system positioning and optical adjustment.
It is designed for alignment purposes only and does not function as a distance-measuring system.
Four protected 21700 lithium-ion cells provide power for the complete system.
The battery configuration includes an integrated protection board and supports charging currents up to 4A.
Battery Configuration
4 × protected 21700 lithium-ion cells
5000mAh capacity
Integrated battery protection
Up to 4A fast charging
Dedicated charger included
Battery endurance varies according to operating cycle, system temperature, battery condition and charging status.
Compared with lower-current charging configurations, the supported 4A charging system helps reduce preparation time between professional operating sessions.
This can be particularly useful for laboratory or engineering projects involving repeated testing over multiple sessions.
An integrated temperature-monitoring system helps protect the internal laser source from excessive heat.
When the internal temperature reaches approximately 45°C, optical output is automatically interrupted.
During testing at approximately 24°C ambient temperature, thermal protection typically activated after approximately 30–40 seconds of continuous operation from a completely cooled state.
Actual operating time varies with:
Ambient temperature
Initial system temperature
Previous operating cycles
Ventilation
Battery condition
For improved thermal stability and component life, shorter intermittent operating cycles are recommended.
For professional projects requiring longer operating periods, customized thermal-management options can be discussed.
Despite the larger 50× focusing assembly, the main system maintains a relatively compact cylindrical form.
