Great Product
Great product, just watch out for the protective film on the mirror surface, hard to spot! Very quick delivery, brilliant price and performs very well. Really happy with these mirrors.

Wow, what a difference they make.
I replaced my Omtech standard mirrors with these and have to say I was sceptical at first, after 5 years I decided it was time to remove the originals and inspect them having cleaned them with alcohol wipes in situ previously. On removal the originals were in quite a state. I fitted the new ones and also aligned the mirrors, the difference was incredible, cutting could be done with less power and at higher speed, these mirrors were a total game changer and well worth the cost.

Withstands 250 W
Tested on a 250 W CO2 laser (3 mm diameter) at max power for 10 minutes or so. Mirror heated up a bit, but no more than another gold mirror in the beampath which cost 25 times more (from Research grade supplier). Second product from this supplier I’ve tried. Slightly lower performance (mirror has a slight bevel to it, see photo) but price is right. I wouldn't do anything silly like touch the gold coating or try to clean it, so maybe not the best for dirty environment.

Relection % and life span.
These look great. The true test is use and how well they transfer the laser beam and long term usage. If they perform as hoped, I will be thrilled.

N'hésitez pas à changer vos miroir pour du GOLD!!
Vous divisez par 2 les passes ou d'un tiers la puissance, je recommande de passer au miroir SI pour un prix mineur...incroyable Machine K40 exemple de coupe: 6mm PMMA coulé 3 passes à 20 watts ou 5 passes à 15 watts 3mm PMMA coulé 2 passes 20 watts Vitesse d'avance 10mm/seconde
