Lenses Provide Laser Damage Threshold


TECHSPEC Laser Grade PCX Lenses 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.


The lenses have a precision UV fused silica substrate and 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 266nm to 15 J/cm2 at 1064nm at 20ns, 20Hz.


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 to 1,000 mm, and a clear aperture of 21.5 mm. TECHSPEC Laser Grade PCX Lenses are in-stock and available for immediate delivery.
