Fused Silica Protective Lens is an optical lens, typically made from high-purity fused silica (also known as quartz), designed to protect other optical components and systems from damage, especially during laser applications like cutting, welding, and engraving. It acts as a barrier against debris, splatter, and the direct impact of the laser beam, preventing damage to more sensitive elements within the optical path.
Made of imported high-purity fused silica with ultra-low thermal expansion coefficient, it can withstand temperatures over 1000°C and resist thermal deformation or cracking during long-term high-intensity operation. Superior thermal stability outperforms ordinary glass lenses significantly.
Double-sided anti-reflective (AR) coating optimized for wavelengths 1064nm/1070nm, achieving an average transmittance of over 99.9%. Minimizes laser energy loss, enhances cutting speed by 5%-8%, and ensures uniform processing quality.
Laser damage threshold exceeds 15J/cm², with hard coating boasting strong adhesion. Resists laser ablation, fogging, and wear, extending service life and reducing replacement frequency and maintenance costs.
