## Customer Reviews

### ⭐⭐⭐⭐⭐ Great lense, great price, great seller!
*by T***A on June 14, 2021*

I bought a new lense to replace the scratched lense that came with my 5w blue/violet laser. The lense I received from this seller was far superior, it increased the performance of my laser. laser now works even better than I had expected.

### ⭐ 98% Yes, Collimated? No
*by M***H on December 8, 2021*

I have some experience with changing lenses in lasers, so this was no surprise. This lens does in fact allow around 98% of the optical power of your laser to come through the diode, but it doesn’t really give the “traditional” beam shape. When installed correctly it provides only the round shape of an unfocused laser, when installed backwards it give the “bow tie” shape. This is the only way to actually focus the beam to a workable dot.Overall, if you don’t care about the aesthetics of a proper beam and dot, please buy this. But if you want a proper laser lens, buy from elsewhere

### ⭐⭐⭐⭐ G2 lens good for cutting and burning
*by D***N on February 27, 2024*

Was as advertised good quality and fitment
