  • This is a power supply unit intended for PLH3D – series laser engraving heads.

  • Our choice

    This air nozzle quickly interfaces with PLH3D-6W–Series engraving laser heads via magnets and also functions as a 43 mm spindle adapter. It directs the flow to prevent dark smoke from impeding the laser light from reaching the sample. This helps to ensure a consistent cutting depth or color when engraving. Smoke can...

  • This Mounted Aspheric lens is useful to collimate or focus laser light in the visible wavelength regime. The aspheric design nearly eliminates spherical aberration without needing multiple optical elements. It has a broadband AR coating of 400-700 nm, allowing it to be used for various applications. 

  • This Mounted Triplet lens can be used to variably focus or collimate the laser light with reduced aberration due to its triplet (three element) design. Its relatively long effective focal length (EFL) of 8 mm allows it to focus laser light to a small spot.

More info

Included parts

- PLH3D-6W v2 laser head

- Beam focus adjuster

- 2 lenses


Advantages of the PLH3D 6W:

- Simple installation in 3D printers and CNC machines

- Accepts a wide range of power supplies

- No additional cooling required

- Driver integrated inside the laser head

- Compatible with accessories for ease of use

- OEM customization available for of 3D printer and CNC machine companies



The focus distance can be quickly set or changed via the included lens adjuster (no additional tools). The driver of the unit is integrated directly on the laser head.  This greatly increases the maximum modulation frequency and allows longer cables to be used.


Control Inputs and Electrical Connection

The laser head has two separate controls. Input #1 accepts 0 - 5V for analog power modulation.  Input #2 accepts 0 - 24V for TTL/PWM and turns on the laser when the voltage exceeds 2.5V. (Input #1 can also be used for PWM if #2 is dedicated for TTL only.)

Important: The laser head should be powered from a dedicated high-quality power supply without anything else connected. Please note: connecting the laser head to the same power supply unit as a CNC machine or any other high-impedance equipment such as stepper motors is not recommended. Doing so may cause extreme instability to the supply voltage and cause damage to the laser head. It also voids any warranty.

Improved Heat Sinking

This lightweight 220g (7.8oz) laser head requires no additional cooling. The body acts as a heat sink, and the fan design allows it to function as an air nozzle protecting the lens from smoke, while also cooling the laser head. Performing tests on several prototype designs allowed us to optimize the heat sink’s shape and enable efficient cooling while maintaining the module’s notably small form factor. 


Accessory for Smoke

The 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 engraved or cut, we offer an optional nozzle that is attachable to the front of unit via magnets built into the laser head (see accessories).



The PLH3D 6W incorporates a thermal protection system that protects the laser diode from overheating to maintain its lifetime. The unit is designed to automatically shut off when the housing temperature exceeds 47C. The analog input is protected by a 5V Zener diode in case on occasion there appears the voltage higher than 5V. Despite everything, this input should not be used with higher voltages due to risk of damage. The laser diode is protected via a Schottky diode, which protects it from a reverse voltage and ESD. In addition, the integrated driver is fully covered to protect it from metal chips in a CNC machine environment.

Alternative functionality

Besides the standard functionality, the small beam spot allows the possibility of using this product for rapid PCB prototyping.  This is done by illuminating copper layer of plates after a photosensitive paste is applied.


Remember that it is not a toy.
Laser radiation is dangerous even when scattered or reflected from any surface.
Always use proper protection laser filter on your CNC machine dedicated to 430 - 480nm in order to avoid reflected radiation.
Never point laser head at people or animals.
Do not touch the beam, it may cause burns or other injury.
Do not stare at the beam or the beam spot while the material is being cut.

Laser radiation - Avoid eye or skin exposure to direct or scattered radiation.
