Frequently Asked Questions
When should I choose an aspherical lens over a spherical one?
Use an aspherical lens when you need to focus a laser beam to the smallest possible spot size, especially with a wide-aperture or high-power beam. The asphere corrects for spherical aberration, which causes rays at the edge of a spherical lens to focus at a different point than rays at the centre.
What is the best lens material for a CO₂ laser?
Zinc Selenide (ZnSe) is the standard material for CO₂ laser optics (at a wavelength of 10.6µm) because it has very high transmission in the infrared spectrum.
What does “diffraction-limited” performance mean?
A diffraction-limited lens is one whose focusing performance is limited only by the fundamental physics of diffraction, not by any imperfections (aberrations) in the lens itself. It produces the smallest possible spot size for a given wavelength and aperture.
