October 4, 2018, Mainz, Germany - Edmund Optics® (EO), the premier provider of optical components, introduces TECHSPEC® Laser Grade PCX Lenses. This new product family includes twenty models of precision lenses, with high surface quality and surface accuracy for a wide variety of high energy Nd:YAG laser applications including laser cutting, machining, and welding.
10-5 Surface Quality
TECHSPEC® Laser Grade PCX Lenses have a precision UV fused silica substrate. They feature λ/10 surface accuracy and 10-5 surface quality, which ensures low scatter and maximum transmitted wavefront performance. The lenses provide an absolute reflectance of less than 0,25% at the coating design wavelength. TECHSPEC® Laser Grade PCX Lenses offer a guaranteed laser damage threshold, designed and rigorously tested to withstand a given level of laser fluence and will not be damaged by the specified laser parameters. Damage thresholds for these lenses range from 3 J/cm2 at 266 nm to 15 J/cm2 at 1064 nm at 20 ns, 20 Hz.
Variety of high laser damage threshold AR coating options available
TECHSPEC® Laser Grade PCX Lenses are available with a 25,4 mm diameter, either uncoated or with a choice of high laser damage threshold anti-reflective (AR) coatings, including most common Nd:YAG laser wavelengths, ensuring maximum laser throughput. The PCX lenses are offered with effective focal lengths ranging from 35 mm to 1000 mm, and a clear aperture of 21,5 mm. TECHSPEC® Laser Grade PCX Lenses are in-stock and available for immediate delivery.
