SPA™ UV-grade fused silica
asphericon SPA™ UV-grade fused silica can be used for wavelengths starting with 185nm as well as for high-power laser applications >1 KW.
All designs are diffraction limited for wavelengths of 230 to 408nm, but are also useable for wavelengths up to 2150nm.
Partially automated manufacturing processes enable the fabrication of standard aspheres with exceptional quality levels in high quantities. asphericon SPA™ UV-grade fused silica are availabe in three diameters (12.5, 25 an 50mm) and can be combined with four different standard coatings. In case of interest we also offer individual coatings.
Our lens design is optimized for multiple apllications - as prototypes in test devices or as OEM-application for beam-focusing or collimating.
All SPA™ UV-grade fused silica aspheres are generally available off-the-shelf in one quality level („Standard“).
