Product Details

Unlike traditional focusing lenses, these lenses should be used with the plano side facing the light source.

Designed and Coated for Nd:YAG Laser Wavelengths
Aspheric Figure Error of 1.6λ RMS and 6λ PV
Modified TECHSPEC® PCX Lenses

TECHSPEC® Hyperbolic Aspheric Lenses are TECHSPEC® PCX Lenses that have been modified to include a mild aspheric surface to provide superior performance at specified wavelengths. Unlike the preexisting spherical lenses, TECHSPEC Hyperbolic Aspheric Lenses produce diffraction-limited spot sizes at the design wavelength, which is ideal for focusing or collimating applications. Any standard lens from Edmund Optics can be modified similarly to TECHSPEC Hyperbolic Aspheric Lenses to create your ideal surface and offer a low-cost boost to performance and to provide the best solution for specific application needs.

Note: Unlike traditional focusing lenses, these lenses should be used with the plano side facing the light source.
