Edmund Optics has introduced 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 per cent 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 3J/cm2 at 266nm to 15J/cm2 at 1,064nm at 20ns, 20Hz.
Variety of high laser damage threshold AR coating options available
Techspec Laser Grade PCX Lenses are available with a 25.4mm 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 35mm to 1,000mm, and a clear aperture of 21.5 mm. Techspec Laser Grade PCX Lenses are in-stock and available for immediate delivery.
