What are the characteristics of sphero cylindrical lens
Sep 16,2022
The sphero cylindrical lens is a Calcium fluoride lens for the vacuum ultra-violet. Anamorphic expansion. These Calcium fluoride negative sphero cylindrical lenses are suitable for anamorphic expansion at vacuum ultra-violet wavelengths.
The sphero cylindrical lenses are ideal for use with excimer lasers. Anti-reflection coatings are available as listed earlier in this section. To order an anti-reflection coated lens simply append the wavelength in nanometers to the product number.
Specifications of the sphero cylindrical lens. Its material of it is VUV CaF2, the Surface Flatness is < λ/4 @ 633 nm, the Surface Quality is less than 20/10(both sides), and the Centration Error is ≤3 arcmin.
The Focal Length Tolerance of the sphero cylindrical lens is <±0.5%, Diameter Tolerance: <+0.00/-0.20mm, Thickness Tolerance: <±0.25mm and Clear Aperture: ≥85% of central dimension.
Through the above introduction and analysis of What are the characteristics of the sphero cylindrical lenses, hope it helps you.
