Good replacement for ULS Lens.
Used to replace the lens in my Universal Laser Systems machine, saving several hundred pounds compared to an original replacement part. Delivered next-day too. My machine uses an RF laser rather than a CO2 laser, but this lens seems to work just as well. Simply removed the old lens from the metal holder and glued the new one in place.

Good value, good fit.
Lens worked well in my k40 and there where no fitment issues. Slightly better cut but can't say huge improvement over the stock, perhaps just got a better stock lens.

ENCAISSE 150W SANS BRONCHER : COUPE NETTE ET REVÊTEMENT SOLIDE
CONTEXTE DU TEST : Installée sur une découpeuse Laser CO2 de 150W (une puissance qui ne pardonne pas les optiques de mauvaise qualité). Je l'utilise principalement pour de la découpe. ✅ ANALYSE TECHNIQUE : Résistance thermique (Le crash test) : À 150W, beaucoup de lentilles "budget" chauffent et finissent par fissurer. Celle-ci tient parfaitement la charge. Le matériau (ZnSe CVD) dissipe bien la chaleur, signe d'une bonne pureté. Qualité de coupe : La focale annoncée de 2" (50,8mm) est respectée. Le point focal est fin, ce qui me donne des bords de découpe bien verticaux et nets. Entretien : Le revêtement (coating) semble de bonne facture. Elle s'encrasse peu et surtout, elle se nettoie très facilement (avec les produits adaptés) sans que le traitement de surface ne parte ou ne se raye instantanément. Dimensions : Le diamètre de 15mm est précis, elle rentre parfaitement dans le porte-lentille sans jeu. 💡 RAPPEL D'INSTALLATION (Pour les débutants) : N'oubliez pas le sens de montage : Côté bombé (convexe) vers le haut (vers le laser), côté plat vers le bas (vers la matière). Si vous la mettez à l'envers, vous aurez un focus diffus et une perte de puissance énorme. VERDICT : Une excellente lentille de remplacement qui n'a rien à envier aux optiques d'origine souvent vendues 3x plus cher. Si elle tient sur mon 150W, elle tiendra sur vos machines 40W ou 80W sans problème. Je valide.

Great replacement part for my laser cutter
Used this to replace the 6 year old lens on my 100W CNC laser which looked a bit cloudy. Cut mostly balsawood, plywood, and magnetic rubber. Could not believe the difference in cut quality with the new lens, I guess I should replace it more often!

Good quality, well packed.
Works perfect. May be a tiny larger dot that my other lense, Kurf needed some adjustment.
