Professional 915nm 120W Laser Igniter with 20× Adjustable Beam Expander

Product Overview

The Professional 915nm 120W Infrared Laser Igniter combines a rechargeable handheld laser unit, an aluminum-alloy housing, and a removable 20× adjustable beam expander.

A coaxial red aiming light assists alignment, while the adjustable optical system allows manual focusing. The removable beam expander can be detached for storage and transport.

Designed for intermittent operation by trained adult users in controlled environments.

Key Features

• 120W rated optical output

• 915nm infrared wavelength

• 20× adjustable beam expander

• Manual focus adjustment

• Coaxial red aiming light

• Rechargeable lithium-ion battery pack

• Compatible charger included

• Aluminum-alloy housing

• Removable optical accessory

Technical Specifications

The 20× designation refers to the beam expander’s nominal expansion ratio. It does not describe the lens diameter or multiply the laser’s optical output power.

20× Adjustable Optical System

The included 20× beam expander provides manual optical adjustment in a removable accessory.

The coaxial red aiming light assists positioning. The main 915nm infrared output is invisible, and the red aiming light does not indicate whether the main beam is emitting or whether exposure is safe.

Performance varies with optical adjustment, working distance, environmental conditions, and the characteristics of the material being tested. No fixed ignition distance or ignition time is guaranteed.

This listing includes the 20× beam expander. Other configurations shown in comparison images are sold separately.

Rechargeable Battery System

The unit includes a rechargeable lithium-ion battery pack and a compatible charger.

• Rechargeable battery pack

• Replaceable battery design

• Compatible charger supplied

• Replacement batteries available separately

Use only the supplied charger or an approved compatible replacement. Charging time depends on the charger specifications, remaining battery charge, and battery condition.

Intermittent Operation

This model is intended for intermittent use. Follow the operating limits supplied with the unit and allow sufficient cooling between activations.

Keep ventilation openings unobstructed. Stop operation if the unit becomes unusually hot, output changes unexpectedly, or the equipment shows signs of damage.

Battery endurance depends on activation duration, cooling intervals, battery condition, and ambient temperature. Continuous-duty operation is not supported by the available specifications.

Important Safety Information

High-power invisible infrared laser radiation can cause serious eye injury, skin injury, fire, and property damage. Direct and reflected beams are hazardous.

This equipment is intended only for trained adult users in a controlled laser work area.

• Use laser safety eyewear appropriate for 915nm and the device’s output. Ordinary sunglasses are unsuitable.

• Use appropriate beam containment, a suitable beam stop, and controlled access. Eyewear alone does not make operation safe.

• Never look into the output opening or view the beam through optical instruments.

• Never direct the beam toward people, animals, vehicles, or aircraft.

• Keep reflective objects out of the beam path.

• Keep combustible materials outside the intended work area and maintain appropriate fire precautions.

• Keep children and unauthorized users away from the equipment.

• Switch off and disconnect the power supply before cleaning, inspecting, or changing optical accessories.

• Inspect the unit, battery, and charger before use. Discontinue use if any component appears damaged.

• Follow the supplied instructions and applicable requirements for laser ownership and operation.

The red aiming indicator does not represent the full extent of the infrared beam hazard.

Care & Maintenance

• Clean optical surfaces using manufacturer-recommended optical cleaning materials.

• Avoid touching the lens surface directly.

• Fit protective caps when available and store the unit in a suitable protective container.

• Keep the housing and ventilation openings clean and dry.

• Inspect threaded connections regularly for secure attachment and damage.

• Store in a cool, dry location away from direct sunlight and unauthorized access.

• Follow the battery manufacturer’s recommended storage charge level and inspection schedule.

• Do not use a damaged battery, charger, cable, or connector.

Frequently Asked Questions

Is the battery rechargeable?

Yes. The package includes a rechargeable lithium-ion battery pack and a compatible charger.

Which beam expander is included?

This listing includes a 20× adjustable beam expander.

Does 20× mean the lens diameter is 20mm?

No. 20× describes the nominal expansion ratio, not the lens diameter.

Does the beam expander increase the laser’s output power?

No. The rated optical output remains 120W. The beam expander changes the beam’s optical characteristics.

Is the main laser beam visible?

No. The 915nm infrared output is invisible. A separate red aiming light assists alignment.

Can the unit operate continuously?

This model is intended for intermittent operation. Follow the supplied operating instructions and allow cooling between activations.

Can I purchase an extra battery?

Yes. Replacement battery packs are available separately. Confirm compatibility with your unit before ordering.

Is a carrying case included?

A carrying case is not included in the standard package listed above. It is included only if expressly stated in your selected package option.

Are laser safety glasses included?

Safety eyewear is not included in the standard package listed above. Obtain suitable eyewear and establish appropriate laser safety controls before operation.
