Featuring low-absorption (<50 ppm at 1.03–1.08 microns), fused silica substrates, 1 Micron Optics include lenses, protective windows, and nozzles for OEM high-power fiber laser systems. AR coatings on lenses and windows have high laser-damage threshold (>10 J) for extended life, while minimal absorption ensures quality cutting without thermal lensing and focus shift. With pinpoint focal length tolerance of ±0.5%, Fiber optics suits all 1 micron applications in 1,030–1,080 Nm range.
