Product Description

Product Description

SILL S4LFT4010/328 Telecentric Laser Scan Lens

The SILL S4LFT4010/328 is a high-quality telecentric f-theta scan lens designed specifically for laser systems operating in the 1030 to 1090 nm wavelength range, making it ideal for laser marking, cutting, and micro-processing applications. It features a 100 mm focal length and a scan area of 35×35 mm, delivering precise and consistent focus with minimal distortion across the entire scanning field. Manufactured from premium fused silica with advanced anti-reflective coatings, this lens ensures over 98% transmission efficiency and low thermal absorption, which reduces heat-induced focus shifts. Its telecentric design guarantees stable spot size and focal position throughout the scan, crucial for high-precision laser processing. The lens has a durable M85×1.0 mounting thread and compact dimensions (106 mm diameter, 30.2 mm length), allowing easy integration into various laser scanning setups. It supports short pulse, ultrashort pulse, and continuous-wave lasers, with a damage threshold of 5.0 J/cm², providing excellent reliability in industrial environments. The SILL S4LFT4010/328 offers exceptional optical performance combined with mechanical robustness, making it a preferred choice for manufacturers seeking accuracy and durability in laser optics..
