YAG F theta scan len SL-1064-174-254-LP

Opex SL-1064-174-254-LP F-theta Scan Lens

1064nm Fiber Laser Marking Field Lens

The Opex SL-1064-174-254-LP is a high-performance F-theta scan lens optimized for 1064nm fiber lasers, designed to deliver precise, flat-field marking across a 174×174 mm working area. With a 254mm effective focal length (EFL) and a compact form factor, this lens balances sharp focus, low distortion, and high energy efficiency for industrial laser applications.

Key Features

●

1064nm Wavelength Optimization: High-transmission anti-reflective coating ensures 97% light throughput, maximizing laser power utilization.

●

174×174mm Uniform Scan Field: Delivers consistent spot quality (50.2–61.3μm) across the entire working area, eliminating edge-to-center focus variation.

●

254mm EFL & 262.47mm Working Distance: Compact design ideal for benchtop and production laser marking systems.

●

Standard M85×1 Thread Mount: Seamlessly integrates with most 1064nm galvo scanners and laser marking machines.

●

Low Telecentricity (<13.2°): Minimizes marking errors at field edges for precise, distortion-free engraving.

●

Industrial-Grade Durability: Black anodized aluminum housing and protective window ensure reliable performance in continuous operation.

Common Applications

High-precision fiber laser marking and engraving

PCB, electronics, and metal component marking

Small-format industrial laser processing

Medical device and automotive part traceability marking

Compatible with all standard 1064nm fiber laser sources and galvo scanning systems, this lens offers reliable performance for both OEM integration and end-user laser equipment.
