PLH3D-XT8 45W: More Powerful than CO2 Lasers, Yet More Energy Efficient

The PLH3D-XT8 laser head revolutionizes the laser cutting and engraving industry, eclipsing the most popular CO2 lasers not only in power but also in energy efficiency. In terms of energy consumption, while a CO2 laser consumes around 650 W to deliver the same amount of energy, a blue laser like the PLH3D-XT8 requires only about 200 W. Furthermore, the PLH3D-XT8's 45 W power output not only outperforms the typical 40 W CO2 lasers but also demonstrates Opt Lasers' market leadership in laser head manufacturing. Opt Lasers' careful design and engineering of the PLH3D-XT8 guarantee outstanding performance and dependability.

The laser spot size of the PLH3D-XT8 is below 200 um, enabling it to achieve extremely precise details and making it clearly visible during operation. This precision, combined with its ability to effortlessly cut through materials like 15 mm wood, establishes the PLH3D-XT8 as the fastest laser head in its class, suitable for both intricate artistic work and robust industrial applications. In essence, the PLH3D-XT8 represents a significant advancement in laser technology, offering unparalleled power, superior energy efficiency, and the capability for highly detailed work, making it ideal for a wide range of cutting and engraving needs.

Features & Benefits of the PLH3D-XT8 Laser Head In Details

Superior Focus Depth Without the Height Adjustment Hassle - Say goodbye to the challenges of working with uneven, bent, or rough surfaces. The PLH3D-XT8 laser head, with its remarkable focus depth and extended beam waist, is uniquely adept at handling surface irregularities. This means consistent, effective laser processing on both curved and flat surfaces without the need for constant adjustments or leveling. Moreover, the XT8 achieves high-performance in single-pass cutting, comparable to multi-pass methods with Z-axis adjustments, making it a perfect choice for users who value efficiency and quality in a straightforward, less hands-on approach.

PLH3D-XT8's Integrated and Adjustable Air-Assist Nozzle  - The PLH3D-XT8 features an advanced built-in adjustable Air-Assist nozzle for optimal setup in both thin material engraving and efficient thick material cutting. Its proprietary design significantly enhances the cutting process by removing debris, maintaining clarity, and accelerating cutting up to six times. The shape-evolvent nozzle ensures even pressure distribution, minimizing waste re-aspiration and aligning hot air flow with the laser beam. This precise airflow control not only boosts cutting efficiency but also reduces heat-related damage risks. The PLH3D-XT8's Air-Assist nozzle exemplifies our dedication to advanced, efficient, and precise laser solutions.

Two Operating Modes for Grayscale Engraving and Full-Power Cutting Modes - The PLH3D-XT8 laser head offers two power modes: 50% for grayscale engraving and 100% for high-speed black and white engraving and efficient cutting. The 50% mode, using about 0-20W, is perfect for detailed grayscale work, providing precision in shade rendering. The 100% mode excels in rapid cutting, even through thicker materials, and achieves clean cuts in a single pass without sacrificing quality. It leverages all laser diodes for full capacity operation, suitable for high-power tasks while still supporting a wide range of PWM signal variations for grayscale versatility. This adaptability makes the PLH3D-XT8 ideal for various materials and applications, from fine engraving to effective cutting of thick materials.

Copper Heatpipe Heatsink: The Ultimate Solution for Efficient Cooling - The Copper Heatpipe Heatsink Technology employed in our systems represents a pinnacle in cooling efficiency. This advanced technology utilizes a special gas that rapidly changes phase, enabling swift heat absorption and transfer. The heat is efficiently conveyed from the source to an additional heatsink, ensuring optimal cooling performance. This method is not only highly effective but also enhances the overall stability and longevity of the equipment by maintaining a consistently lower operating temperature.

Signaling LED for Enhanced Operational Awareness
The PLH3D-XT8 laser head is equipped with a signaling LED, indicating when the unit is armed and ready. This LED is a critical safety feature, signaling that the laser will activate upon receiving a modulating signal. It enhances operational safety by ensuring users are aware of the laser's armed status. The LED also serves as an overheating indicator: it blinks if the ambient temperature exceeds 40°C (104°F) and shuts down the laser head at temperatures of 45°C (113°F) or higher, ensuring both safety and proper temperature management.

Strongest Fan Available on the Market in its Size  - Cooling is not the only thing that the fan is doing - it moves 92 m3 of air per hour (52 CFM), providing a great smoke removal system.

The Superfast Built-In Driver for Unmatched Performance - Opt Lasers leads in innovation by integrating a superfast laser diode driver directly into the cutting and engraving laser head, marking a significant advancement in technology. The close proximity of the laser diode to the driver not only ensures enhanced protection for the laser diode but also enables high-frequency current modulation. This capability is essential not only for achieving precise and rapid engraving results but also for accurately reproducing shades of gray. Additionally, this design effectively eliminates inductance effects that typically occur during switch-on, thereby enhancing both performance and reliability.

Hassle-Free Installation for OEM Applications - The PLH3D-XT8 laser head is designed with a focus on ease of integration, particularly for OEM applications. It features an accessible yet protected screw terminal connection, simplifying the installation process. This thoughtfully designed connector is easy to connect, ensuring a hassle-free setup. Moreover, its strategic placement under a cover shields it from dust and debris during operation.

OEM Customization is Available for Manufacturers of 3D Printers and CNC Machines.
