FAQ
5W is the optimal balance for desktop size, cost, and high-precision engraving.
UV lasers have a short wavelength and high-energy photons, which directly break molecular bonds with very little heat. This “cold processing” delivers much higher energy density and precision than traditional heat-based lasers.
That’s why 5W is considered the golden power level for desktop UV systems. Even for demanding tasks like 3D engraving inside glass, the F2 Ultra UV typically uses only around 60% of its power—leaving plenty of performance headroom.
It includes:
- 1 × Inner engraving lens
- 1 × Riser
- 1 × K9 glass block (for testing/calibration)
- 3 × Inner engraving calibration cards
Inner engraving and surface engraving require different lenses. This pre-calibrated pack lets you switch modes easily and accurately.
Absolutely not. Please note that F2 Ultra UV and F2 Ultra are not the same machine. They use different light sources and different interfaces, so their field lenses are not interchangeable.
The key difference:
They are two machines with completely different “engines.” They share the “F2 Ultra” flagship series name—indicating they are both high-end galvanometer systems—but they are designed for entirely different materials and applications.

Genuine Praise from Real Users
"We are getting some super fine detail and probably the cleanest engraving—actually, it's not probably, it is the cleanest engraving out of any external laser so far."
"From a small business perspective, if you want to just batch out a ton of whiskey tumblers, glassware… it makes it easy."
"What xTool has done a really good job of, it makes this process fairly simple. you can just import a 3D model and then just place it wherever you want inside of the crystal."
"So F2 Ultra UV is the jack of all trades laser. Basically, it can work with almost every material across the board. This machine can do 3D crystal engraving. This is the only type of laser that can do that."
"With F2 Ultra UV, there's absolutely no cleanup and no signs of any residue."
