Description
Short Description
A compact 120W experimental laser device featuring a 3D-printed housing, 10× adjustable optical lens, green coaxial aiming, digital voltage display, constant-current drive, and an integrated thermal protection system. Designed for qualified scientific experiments and technology demonstrations, with multiple built-in safety and cooling features for controlled operation.
Product Description
120W 3D-Printed Handheld Laser Device
Built around a lightweight 3D-printed enclosure, this 120W handheld laser system combines an adjustable 10× optical lens, green coaxial aiming module, constant-current laser driver, and active thermal management in a compact portable platform.
The device is designed for controlled scientific experiments, optical research, and technology demonstrations where precise positioning and thermal management are important.
Key Features
- 120W high-power laser output
- 3D-printed lightweight housing
- 10× adjustable optical lens
- 110mW green coaxial aiming system
- 4 × LG 3000mAh lithium cells
- 20A battery protection board
- Constant-current laser driver
- Automatic over-temperature protection
- Dual-fan active cooling
- Large copper heat-spreading block
- Digital voltage display
- DC charging interface
- Charger included
Intelligent Temperature Protection
An integrated thermal protection switch continuously monitors the internal operating temperature. When the temperature exceeds approximately 45°C, the protection system automatically interrupts power to help prevent excessive heat buildup.
The dual-fan cooling system works together with the large-area copper heat-spreading block to improve heat dissipation during normal operation.
Battery & Power Management
The device uses four LG 3000mAh lithium cells together with a 20A battery protection board and constant-current drive circuitry.
The integrated voltage display allows the operator to monitor battery status. When the displayed voltage falls below approximately 14.8V, recharge the device before further operation.
Charging: DC input
Charger: Included
Adjustable Optical System
The integrated 10× adjustable lens provides flexible optical focusing and beam positioning. The green coaxial aiming system helps indicate the approximate optical direction before operation.
For controlled operation, avoid positioning the optical output directly against nearby surfaces.
Important Safety Information
This is a high-power laser device and is not an ordinary laser pointer. Improper use can cause serious eye injury, burns, fire, or damage to surrounding objects.
- Never point the laser toward people, animals, vehicles, aircraft, or occupied areas.
- Never look directly into the optical output or any reflected beam.
-
Use appropriate laser safety eyewear matched to the actual operating wavelength.
- Avoid mirrors, polished metal, glass, and other highly reflective surfaces.
- Do not operate the device while it is in contact with the target surface.
- Maintain a safe separation distance from the target.
- Allow the device to cool between operating cycles.
- Do not modify, disassemble, or bypass the thermal or battery protection systems.
- Keep away from flammable materials and uncontrolled environments.
- Store the device securely and keep it inaccessible to unauthorized users.
Important: The exact laser wavelength and required protective-eyewear specification should be confirmed from the final laser module configuration before use. Do not rely solely on the green aiming beam to determine the invisible laser wavelength.
