Exceptionally Accurate Metal Engraving
PLH3D-XT-Series engraving laser heads were devised as a series of specialized laser heads for engraving with extremely high resolution and cutting thin materials with ultra-thin lines. Based on our 6W-Series laser heads, XT-Series laser heads inherited all their advantages: versatility, compact dimensions and high-speed driver. The microscopic beam spot allows to make precise and very small size engravings in a wide variety of materials including stainless steel.
Ultra-HD Ceramic Tile Engraving
The 500 DPI capability allows for amazing quality engravings on materials like ceramic tiles. Higher power density reveals new engraving and cutting possibilities. Additionally, engraving and cutting processes are significantly faster comparing to laser heads without anamorphic optics.

High-End Detailed Engraving & Cutting on Soft Materials
PLH3D-XT-50 laser heads, thanks to the fact that they achieve a spot width of less than 50um, also allow cutting materials with care for a thin even cut line. For comparison, a typical human red blood cell is 5-10um in size, and the diameter of a single human hair is 50-20um.

Key Strengths of the XT Series
Microscopic & Square Beam Spot
All of the laser heads from PLH3D-XT-Series are distinguished by microscopic and square beam spot. PLH3D-XT-50 laser head is achieving beam spot width below 50um and PLH3D-XT-10 even below 10um. The square spot allows for perfect details when rasterizing graphics, and also ensures consistent thickness of the cutting line, so that even small details are perfectly reproduced according to the design. With the XT-50 you can achieve an ultra HD resolution of over 500 DPI and with XT-10 even 2500 DPI.
High Power Density
As known power density is defined how much power is located in certain area. Typically it is specified in kilo wats over cm2 or mm2 (kW/cm2 or kW/mm2). This parameter is one of the most crucial parameter for cutting or engraving different materials. PLH3D-XT-Series laser heads are designed to achieve small beam-spot size the outcome of this proportional increase of the power density. Higher power density reveals new engraving and cutting possibilities. Additionally, engraving and cutting processes are significantly faster comparing to laser heads without anamorphic optics.
Powered by Blue Laser Diodes
Unlike infrared light, blue light is more easily absorbed by numerous industrial materials. This directly translates to several advantages including reduced power consumption and more compact heat sinking.
Integrated Control Electronics
In many laser heads that have the diode connected to the diode’s driver via a long cable and the coupling is done with connectors. Long wires are characterized by substantial inductive effects. This results in delays of the diode’s response in relation to the diode’s driver and as extension it also results in blurred lines. Connectors are more prone to disconnections than coupling done via direct soldering. Disconnecting during laser processing can damage the laser head.
Opt Lasers laser heads are industry-level grade CNC machine tools. Mechanical parts are made from machined aluminium. Our products are designed with cooling optimization in mind. Investing in the highest quality equipment ensures the best performance and price.
Lightweight Design Mounts to Nearly any CNC Machine
Featuring a lightweight, Aluminum body that makes the laser weight less than 370 g. As a typical CNC spindle weighs approximately 1.8 kg, CNC machines can operate it effortlessly.
Can be set on nearly any CNC machine since it accepts both analog and PWM CNC signals.
No warm-up time
LaserDock (Included in the Kits) – Speeds up your work and keeps your laser clean
An effective solution for both large and small CNC machines and 3D printers, this magnetic docking station allows the PLH3D-XT Series laser for engraving to be quickly attached or removed. This facilitates quick access for CNC milling or 3D printing. By protecting the laser head from plastic or wood dust from your printer or CNC mill, it can extend the lifetime of the engraving laser and reduce maintenance. It also allows you to take advantage of the entire working area of your 3D printer or CNC machine.
PLH3D-CNC Adapter (Included in the Kits) - Easy connection to any CNC machine
Many types of CNC machines and 3D printers with different control voltage standards and levels available on the market may be used to control the PLH3D head. The PLH3D-CNC Adapter converts all these signals to the standard compatible with the PLH3D head. The PLH3D-CNC Adapter contains widely used industry-standard screw connectors. A dedicated desktop low-noise power supply unit assures compatibility and reliability as well as eliminates problems caused by using third-party power supplies. The general status (power, armed, laser working) may be checked at a glance by watching three LEDs.
Laser Safety Glasses (Included in the Kits) - Ensure the highest quality of protection
These laser glasses can help reduce the probability of light entering the eye from the diffusely reflected laser light. It is important to note that while these laser glasses may be helpful at adding an additional layer of safety for diffusely scattered light, the user should not depend on them to protect against the beam entering the eye, either directly or indirectly. It is necessary to take additional precautions when working with lasers, receive proper training on how to do so and not depend on equipment as an alternative to safe practices.
Other accessories (Included in the Kits) - To make your Opt Lasers Kit plug & play
With these accessories, it is a plug & play kit. Height Reference - helps you set your working distance, power adapter with AC adapter to allow you to plug into all outlets (US, AU and Europe), wiring and screw set to connect everything together and mount to connect the machine.
Blue Laser Safety Window (Compatible with all Blue Lasers) - Install as you need
These laser windows can help reduce the probability of light entering the user’s eye from a diffusely backscattered laser light. This product is rated at OD 6+ over the range of 190 to 540 nm, blocking deep ultraviolet to green including violet and blue light.
High-Pressure Air Assist Nozzle (Included in the Kits) - Speeds up laser engraving and cutting up to 6 times
Being compatible with the XT and XF+ Laser Head, the High-Pressure Air Nozzle is a priceless asset for laser cutting and engraving. Not only does it speed up cutting and engraving with laser by up to 6.5 times, but it also substantially improves the attained quality of the processed material. With the High-Pressure Air Nozzle your yield will have noticeably enhanced quality with uniform and well-defined features. Our High-Pressure Air Nozzle will also protect your optics from smoke and dust particles, extending the intervals between subsequent lens cleaning routines, and boost user safety.
