Built-In Driver with Unmatched Performance - The Heart of The Laser Head

Opt Lasers leads in innovation by being the first to integrate a superfast laser diode driver directly into the cutting and engraving laser head. The built-in driver, the heart of the laser head, ensures enhanced protection for the laser diode. As a manufacturer of laser diode drivers, Opt Lasers has leveraged years of experience to create a highly efficient driver with low power consumption and minimal heat production. This makes using the cutting and engraving lasers at high speeds feasible, even for small details or tight radius turns, thanks to the driver's ability to process all necessary signals swiftly. Moreover, with a maximum driver current of 6A, operating it at 3-4A ensures longevity and reliability, providing an offset for extended driver life.

  • Maximum output current capacity: 6 A
  • Typical output current: 3-4 A
  • Input voltage 24 V
  • Integrated microcontroller for temp. measurement and soft start
  • Thermal protection system: 45 °C
  • Soft start for diode protection
  • Electrostatic discharge (ESD) protection

Opt Lasers XT8 on X-Carve is a huge upgrade from Xtool P2.


Highly satisfied!

Works incredibly well with my X-Carve Pro.


great to go with

Based on my experience with various laser engraver providers, Opt Lasers set the standard for laser technology with their cutting-edge products.


great deall

This laser cutter is a fantastic addition to my X-Carve.


Higher performance than anything

Opt Lasers XT8 is a more cost-effective solution with higher performance than anything I purchased from Jtech Photonics.


Very satisfied with this purchase.

Fantastic results on my X-Carve.



A definite power up when it comes to engraving capabilities, both when it comes to detail and larger parts, where the laser performs admirably

stainless steel

i got even higher speed than in chart! awesome!


happy owner of XT8

I mainly work with parts for bars, like beer pouring handles or seats, and laser engrave the lettering or design as they order. It comes very easily and is precise


Good job OPT!

Great work ! Love it

чудесно за детайли и за по-големи компоненти


likee it

It is not that heavy like I thinking - great power


The PLH3D-XT8 brings now possibilities to light

I have had many diode lasers, but this one truely is a leap forward. The combination of increased power, and increased focal length really allows deep cutting and engraving that can replace a spindle in many cases, as well as allows marking on uneven surfaces due to reduced sensitivity in focus.

Very easy to use

I sincerely recommend


The best laser on the market

Top quality



Snelle levering en professionele service


fast and powerfull

PLH3D-XT8 allows my creativity to exploode ha!



was fast delivered, i got updated by email


truly amazing

The detailed work I can now achieve with this laser head is phenomenal. Truly a cut above the rest.


Su precisión inigualable

Con años de experiencia a mis espaldas, es raro encontrar una herramienta que cambie mi forma de trabajar. La PLH3D-XT8 lo ha conseguido.


cutting plexi

I am most happy for cutting plexi - now it's a real process not like with cheap lasers from china
