TECHSPEC® Ultrafast Thin Plano-Convex Lenses are designed with an ultra-thin center thickness to provide a low group delay dispersion (GDD) for ultrafast laser pulses. These ultrafast lenses are IBS AR-coated for wavelengths from 370nm to 2.2μm ideal for use with common ultrafast laser wavelengths. The broadband coating provides less than 0.1% reflectance across the design wavelength range. TECHSPEC Ultrafast Thin Plano-Convex Lenses are ideal for collecting and focusing light from ultrafast laser sources and their corresponding harmonics, including Ti:sapphire, Yb:doped, and Nd:YAG, Holmium, and Thulium lasers. These thin PCX lenses are available in standard sizes with effective focal lengths from 50mm to 2000mm.
