High-power field lens for 1064nm machine
1 What makes our high-power field lens different from regular ones?
You know that feeling—when you crank up the power, things go sideways.
At low wattage, the lens stays cool. The spot and focus stay sharp. But at high power, regular field lenses can’t keep up. They absorb heat, distort, and lose focus. The spot gets bigger. The edges don’t cut deep enough or penetrate at all. Your reject rate jumps.
Our 2000W‑class field lens is built specifically to beat that “heat sickness.”
We use coatings and substrates with extremely low absorption. Laser energy can’t heat the lens much, and any heat that does build up dissipates fast. You can run it all day at full power. The focal length stays rock solid.
No matter where the galvanometer sends the beam, the spot size and energy density stay the same. Edge and center get equal treatment. You get consistent results across the whole field.
In plain terms:
Low-power lenses are all about precision. High-power lenses are about stability on top of that precision.
If you weld large areas, engrave deeply, clean, or cut with high power, this lens is for you. Stop refocusing and recalibrating. Save time and process more parts — that’s a win.
