PLH3D-6W-XF+ Engraving Laser Head
Our best-selling professional 6 W engraving laser designed for industrial applications with a lens adjusting tool and a free High Efficiency Lens. Features a robust design and compatibility with all types of control signals used in CNC and 3D printing market. It can be powered with various PSUs and boasts the most powerful fan for its size, providing outstanding cooling and smoke removal.
- Laser Diode Optical Power: 6 W
- Focus Distance: 20 - 120 mm
- Max. Power Consumption: 30 W
- Laser Diode Wavelength: 450 nm
- Modulation Input 1 : 0 - 5V Analog/TTL/PWM
- Modulation Input 2: 0 - 24V TTL/PWM
The focal distance can be quickly set or changed with the included lens adjuster (no additional tools are required). The driver of the unit is integrated directly within the engraving laser head. This feature increases the maximum modulation frequency remarkably, and allows longer cables to be used.
Besides the standard functionality, the small beam spot introduces the possibility of using this product for rapid PCB prototyping. This is done by illuminating the copper layer of plates with the engraving laser after a photosensitive paste is applied.
Improved Heat Sinking
This lightweight 220 g (7.8 oz) engraving laser requires no additional cooling. The engraving laser's body acts as a heatsink, and the fan design allows it to function as an air nozzle, protecting the lens from the smoke whilst also cooling the laser head. Rigorous testing on several prototype designs allowed us to optimize the heatsink’s shape and enable efficient cooling while maintaining the module’s notably compact design.
Accessory for Smoke (see accessories)
Our 6 W cutting and engraving laser head allows engraving or cutting of materials such as wood, stainless steel, paper, leather, cardboard, and many others. For materials that generate smoke when laser engraved or cut, we offer an optional nozzle that is attachable to the front of the unit via magnets built into the engraving laser head (see accessories).
For bulk orders, the PLH3D series can be customized to all customers' needs. We can add customers' logos and all possible additional features. Customization is offered for all 3D printer and CNC manufacturers and distributors.

Input Signal Versatility - the build-in driver allows accepting a variety of signals 0 - 5 V analog signal and 0 - 5 V, 0 - 10 V or 0 - 24 V for PWM/TTL signal.
The Built-in Driver inside the Engraving Laser Head - Opt Lasers is the first company that integrated the laser diode driver directly into the cutting and engraving laser head. A short connection between the laser diode and a driver ensures better protection for a diode, possibility of high-frequency current modulation as well as eliminates inductance effects during the switch-on.
Accepts a Wide Range of Power Supplies - 12 - 24 V, the integrated high-efficiency DC-DC converter is adjusting the input voltage to proper diode compliance voltage. This reduces the amount of heat generated and ensures over-voltage protection.
No Additional Cooling Required - the distinct shape of the cutting and engraving laser heads provides the best possible cooling method for a 6 W laser diode. Numerous prototypes have been tested to find the best solution for cooling the laser diode. The current design allows the engraving laser to warm up by only 2 - 3 degrees Celsius after a whole hour of constant work at full power.
Two Types of Lenses Included - The High-Resolution Triplet Lens with lens adjuster has a relatively long effective focal length (EFL) of 8 mm, which allows it to focus laser light to a small spot. All 6 lens surfaces are coated with anti-reflection (AR) coating centered at 450 nm. It is usually preferred for engraving a thinner line, cutting a thicker material due to the reduced convergence and divergence, or when a long distance between the cutting and engraving laser head and the plane of the object to be engraved is necessary.
High-Efficiency Mounted Aspheric Lens is designed to transmit as much power as possible from the laser diode. Its short effective focal length (EFL) of 4 mm makes a variety of working distances possible, but makes the focal spot almost twice as big compared to the Triplet Lens. This lens should be used for engraving thicker lines on wood or plastic. This type of lens is used without the lens adjuster since they need to be mounted closer to the laser diode.
Strongest Fan Available on the Market in its Size - cooling is not the only thing that the fan is doing - 43 m3 of air per hour (25 CFM) makes a great smoke removal system. Additionally, the fan has 70000 hours of life expectancy.
Compatible with Accessories for the Ease of Use - ease of work as well as safety is crucial to us. Accessories we produce are of highest quality, milled on CNC machine, which makes the work easy and safe. Please check out the accessories we prepared for the PLH3D series.
OEM Customization is Available for Manufacturers of 3D Printers and CNC Machines.
