UV Laser protective Windows

UV Laser Protective Window

Eternal Optics manufactures precision UV Laser Protective Windows designed to protect critical optical components in advanced UV laser systems. Made from high-quality UV Fused Silica (Fused Quartz), our protective windows provide excellent ultraviolet transmission, low absorption, and high laser damage resistance for demanding laser applications.

A UV Laser Protective Window acts as a protective barrier between the laser optical system and the processing environment, helping prevent dust, debris, smoke particles, and contaminants from damaging expensive optical components such as focusing lenses, scan lenses, and beam delivery optics.

Optimized for common UV laser wavelengths including 355nm and 266nm, our fused silica windows feature high-performance AR (Anti-Reflective) coatings to improve transmission efficiency, reduce reflection loss, and maintain stable performance under high-energy UV laser operation.
