Aspheric lens for Aberration Correction
Feature
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.
