This protective lens is made of high-purity fused silica substrate with dual-sided anti-reflection laser coating, presenting dark uniform optical surface and white smooth edging frame. The specialized coating effectively reflects laser beam and blocks spatter, smoke and metal debris generated during high-power laser processing, preventing internal laser generator contamination and extending the service life of expensive laser resonators. Multiple circular diameters and thickness specifications cover low to high power laser machines ranging from 1000W to 20000W.
The R&D team completed laser transmittance, high-temperature spatter impact and coating adhesion aging tests to optimize coating uniformity and scratch resistance. Custom lens sizes, anti-spatter coating layers and transmission wavelength parameters are available for OEM bulk orders for laser equipment assembly factories and metal laser processing workshops. The polished edge finish avoids light refraction loss and ensures stable laser output precision during long-hour continuous cutting work.
To meet surging global demand for stable laser optical spare parts, Ratop Laser will upgrade its optical coating and precision cutting production line in Q4 2026. The enterprise will keep developing laser protective windows, focusing lenses, collimator lenses and other laser optical accessories for laser industry suppliers worldwide.
