Aspheric lens for Aberration Correction

Aspheric lens for Aberration Correction

Aspheric surfaces can effectively reduce spherical aberration and realize a diffraction-limited performance. Optimal solutions for high precision and high quality laser materials processing by short focal length and large input beam diameter.
A spherical lens with spherical aberration shows differences in focal positions of light rays depending on their distances from the optical axis. Our aspheric lens realize smaller spot diameter than a conventional triplet lens by spherical lenses.

An aspheric lens realize smaller spot diameter by larger input beam diameter.

●Materials

High purity synthetic quartz is used as a ultra-low absorption lens material for high power lasers.

●Coating

The anti-reflection coatings are used on the both side of lenses.
