Laser Collimating Lens D37 F75 F100 WSX KC13 KC15 NC30 NC30B Collimation
High-precision optical collimating lens designed for WSX fiber laser processing heads, specifically compatible with KC13, KC15, and NC30 series. Manufactured from high-purity imported fused silica with dual-sided anti-reflective (AR) optical coating, this lens transforms divergent fiber optic laser beams into aligned parallel beams. Built to withstand laser power levels up to 3kW with minimal thermal lensing and low beam distortion.

Key Features
-
High-Purity Fused Silica Substrate: Ultra-low optical absorption and high laser damage threshold, preventing thermal lens effect and focal drift during high-power cutting.
-
Dual-Sided AR Coating: Anti-reflection coating optimized for 1064nm–1080nm fiber laser wavelengths, achieving light transmittance over 99.5% to maximize energy utilization.
-
Precision Mechanical Fit: 37mm outer diameter manufactured to tight tolerances for direct drop-in replacement into WSX collimation cartridges.
-
Thermal Stability: Low expansion coefficient ensures stable beam geometry and long operational life under continuous industrial cutting cycles.

Handling & Maintenance
-
Cleanroom Handling: Unpack and install only in a clean, dust-controlled environment to prevent airborne contamination on optical surfaces.
-
Protective Gear: Always wear powder-free gloves or finger cots. Never contact the optical surface directly with bare skin.
-
Cleaning Method: Clean using >99.9% optical-grade isopropyl alcohol and non-abrasive optical tissue using a single-direction wipe protocol.
-
Inspection: Regularly check for spatter, burn spots, or coating wear. Replace immediately if degradation is detected to prevent damage to internal laser head optics.
