Laser Focusing Lens D37 F125 F150 F200 F190 WSX KC13 KC15 NC30
High-precision optical focusing lens designed specifically for WSX fiber laser processing heads, including the KC13, KC15, and NC30 series. Manufactured from high-purity imported fused silica with double-sided anti-reflective (AR) optical coating, this lens converges collimated laser beams into a high-density focal point. Engineered for stable continuous operation in fiber laser cutting systems operating up to 3kW.

Key Features
-
High-Purity Fused Silica Substrate: Delivers exceptional optical clarity, low internal absorption, and high threshold resistance to laser damage under continuous high-power operation.
-
Dual-Sided Anti-Reflective Coating: Double-sided AR coating optimized for 1064nm–1080nm fiber laser wavelengths minimizes beam reflection and delivers light transmittance greater than 99.5%.
-
Multiple Focal Length Options: Available in F125, F150, and F200 configurations to accommodate varying material thicknesses, cutting speed requirements, and focal depth profiles.
-
Minimal Thermal Lensing: Engineered to maintain stable focal positioning and prevent spot distortion caused by thermal expansion during heavy industrial cutting cycles.
-
Precision Mechanical Compatibility: Standardized 37mm outer diameter ensures accurate seating and seamless drop-in replacement within WSX focus cartridges.

Focal Length Selection Guide
-
F125 (125mm): Suitable for high-speed cutting of thin sheet metal (1mm – 3mm), providing a smaller focal spot and concentrated energy density.
-
F150 (150mm): Versatile medium focal length optimal for general-purpose sheet metal cutting across thin to medium material thicknesses.
-
F200 (200mm): Extended focal length offering greater depth of focus, recommended for medium-to-thick carbon steel and stainless steel processing.
Compatibility
-
Cutting Heads: WSX KC13 (Manual Focus), WSX KC15 (Manual Focus), WSX NC30 / NC30A / NC30C / NC30E (Auto-Focus).
-
Laser Generator Brands: Fully compatible with IPG, Raycus, Max Photonics, JPT, RECI, and nLight fiber laser sources.
Handling & Maintenance
-
Clean Environment Setup: Perform all replacement and installation procedures inside a dust-free enclosure to prevent particle contamination on the optical surface.
-
Handling Protocol: Always wear powder-free gloves or finger cots. Never make direct skin contact with the optical faces or coating layers.
-
Cleaning Standard: Clean strictly using optical-grade isopropyl alcohol (purity > 99.9%) and non-abrasive lens wiping paper, wiping in a single direction.
-
Routine Inspection: Inspect the optical surface regularly for spatter, debris, or thermal burn marks. Damaged coatings must be replaced immediately to prevent damage to internal head assemblies.
