The 120W 915nm laser system is designed for professional users who need a compact optical platform with flexible focusing across different working distances.
Featuring manually adjustable optics, an integrated Samsung battery pack and coaxial visible alignment, the system can be configured for controlled applications from approximately 1 meter up to 15 meters under suitable conditions.
Its self-contained power architecture eliminates the need for a separate external battery, while an aluminum-alloy housing, dual cooling fans and constant-current driver provide a practical platform for laboratory research, engineering evaluation and professional optical testing.
The system provides up to 120W optical output at a primary wavelength of 915nm.
Its direct-output architecture is designed for professional optical experiments, engineering evaluation and controlled research applications where a compact high-power infrared source is required.
One of the key advantages of this model is its flexible focusing system.
The focusing lens can be manually rotated and extended according to the required working distance.
With appropriate adjustment, the recommended working range is approximately 1–15 meters.
For applications beyond approximately 5 meters, a stable tripod, gimbal or fixed mounting platform is recommended to improve positioning stability.
Actual optical performance depends on focusing accuracy, mounting stability, environmental conditions and target characteristics.
Power is supplied by four Samsung 50E 21700 lithium-ion cells installed inside the main unit.
The integrated battery architecture eliminates the need to connect an external battery pack before operation.
This provides several advantages for professional users:
Faster system preparation
Fewer external cables
Compact transportation
Cleaner equipment installation
Convenient charging
No separate power pack to mount
The complete system can be recharged through its DC charging interface using the supplied charger.
A regulated constant-current driver manages electrical delivery to the laser source.
This architecture helps maintain more consistent electrical performance as battery charge changes during operation.
For professional users, regulated power delivery also provides a more controlled platform for repeatable engineering and laboratory testing.
Two internal cooling fans work together with the aluminum-alloy enclosure to remove heat from the internal laser assembly.
The fans operate when the system is powered, providing continuous airflow during the operating cycle.
An internal temperature-monitoring circuit provides additional thermal protection.
When the internal temperature reaches approximately 45°C, optical output is automatically interrupted.
Under test conditions at approximately 19°C ambient temperature, a completely cooled system typically operated for around 45–60 seconds before thermal protection was activated.
Actual operating time varies with ambient temperature, previous operating cycles, ventilation and system condition.
For improved component life, intermittent operating cycles with sufficient cooling intervals are recommended.
The primary 915nm output is not safely visible to the human eye.
For this reason, the system incorporates a visible red reference laser positioned close to the same optical axis as the primary output.
The visible reference point assists trained operators with preliminary positioning and focus adjustment during controlled setup.
This is particularly useful when changing between different working distances.
A simple rear status indicator provides quick information about the approximate remaining battery level.
Green — High Battery Level
Yellow — Medium Battery Level
Red — Charging Recommended
This allows the operator to check battery status without removing the integrated power pack or connecting additional monitoring equipment.
The main enclosure is manufactured from aluminum alloy, providing a balance between structural strength, thermal performance and portability.
The metal housing also assists the internal cooling system by transferring heat away from the laser assembly.
Combined with the integrated battery and direct-output architecture, the result is a self-contained professional platform that can be transported and installed without a separate power enclosure.

*Working distance depends on the selected optical configuration, focus adjustment, mounting stability and operating conditions.
The system can be configured according to the required working distance.
Suitable primarily for shorter-distance optical setups of approximately 1–2 meters.
Recommended when greater focusing flexibility or longer working distances are required.
For applications beyond approximately 1 meter, a focusing lens is generally recommended.
Whenever the working distance changes, the optical focus should be readjusted rather than assuming that one setting will provide optimal performance at every distance.
As working distance increases, small movements of the main unit can produce larger changes in optical positioning.
For applications beyond approximately 5 meters, mounting the system on a tripod, gimbal or other stable support is recommended.
This helps improve:
Alignment stability
Repeatability
Focus adjustment
Experimental consistency
For fixed laboratory installations, a dedicated mounting platform can also be used according to project requirements.
This 120W 915nm optical platform can be considered for controlled professional applications including:
Optical and photonics research
Laboratory experiments
Engineering evaluation
Infrared system testing
Material-response studies
Thermal-effect research
Industrial R&D
Optical alignment experiments
Technical demonstrations
Customized system integration
Application suitability should be evaluated according to the required working distance, optical conditions, operating environment and applicable safety requirements.
This model is particularly suitable for professional customers who require a balance between portability and adjustable working distance.

This is a high-power professional laser system intended only for qualified personnel operating in secured and controlled environments.
The 915nm output presents serious eye and skin hazards and is not safely visible to the human eye. Appropriate wavelength-rated protective eyewear, controlled access, beam containment and professional laser-safety procedures are required.
Never direct the system toward people, animals, aircraft, vehicles, roads, buildings, windows, reflective surfaces or public areas.
Purchasers and operators are responsible for compliance with applicable laser-safety and local regulatory requirements.
The appropriate optical configuration depends on your intended working distance and application.
For shorter-distance setups, a compact optical configuration may be sufficient. For longer working distances, an adjustable focusing lens and stable mounting solution are recommended.
