Professional 915nm 120W Laser Igniter with 30× Adjustable Beam Expander

Product Overview

The Professional 915nm 120W Infrared Laser Igniter combines a rechargeable handheld laser unit with a removable 30× adjustable beam expander.

A coaxial red aiming light assists alignment, while the beam expander’s rotary adjustment mechanism provides manual optical adjustment. The aluminum-alloy housing provides a durable enclosure for the laser and battery system.

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

Key Features

• 120W rated optical output

• 915nm infrared wavelength

• 30× adjustable beam expander

• Rotary optical adjustment

• Coaxial red aiming light

• Rechargeable lithium-ion battery system

• Compatible charger included

• Aluminum-alloy housing

• Removable beam expander

• Optional protective carrying case

Technical Specifications

The 30× designation describes the beam expander’s nominal expansion ratio. It does not multiply the laser’s optical output power.

30× Adjustable Optical System

The included 30× beam expander features a rotary adjustment mechanism for manual optical adjustment.

The coaxial red aiming light assists positioning. The main 915nm infrared output is invisible, and the red aiming light must never be used to judge whether the main laser is emitting or whether exposure is safe.

Performance depends on optical adjustment, working distance, environmental conditions, and the material being tested. No fixed ignition distance or ignition time is guaranteed.

This listing is for the 30× configuration. 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.

• Battery and charger supplied with the unit

• Replacement batteries available separately

• Suitable for use where mains power is unavailable during operation

Use only the supplied charger or a manufacturer-approved compatible replacement. Charging time varies with battery condition, remaining charge, and charger specifications.

Operating Limits

This model is intended for intermittent use. Allow sufficient cooling between activations and follow the operating limits supplied with your unit.

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

Do not rely on a protective shutdown function as the normal method of ending an activation.

Important Safety Information

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

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

• Use appropriate laser safety eyewear specified for 915nm and the device’s output. Ordinary sunglasses do not provide suitable protection.

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

• 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.

• Use only an approved compatible battery and charger.

• 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

• Keep the optical surfaces clean using manufacturer-recommended optical cleaning materials.

• Avoid touching the lens surface.

• Fit protective caps when the equipment is not in use.

• Keep the housing and ventilation openings clean and dry.

• Inspect the optical mount and threaded connections regularly.

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

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

• Stop using the unit if the battery, charger, wiring, or housing becomes damaged.
