Cylindrical concave metallic coated mirrors are used for focusing light to a thin line without chromatic aberration. Being metallic coated, mirrors work as reflectors in broadband spectral range. Most common application for cylindrical mirrors is either beam expansion or line generation. Altechna offers gold, silver and aluminum as standard coatings, but other type mirrors coatings such as chrome, copper, dielectric high reflection or partial reflection are available on request.
varna Protected gold provides excellent, broadband infrared high reflectance
varna Protected silver provides higher reflectance than aluminum throughout the visible and near IR
varna Protected Aluminum is economical solution for VIS applications
varna UV enhanced Aluminum provides good reflectance over a wide range and are mainly used in UV applications
varna Custom made lenses, dielectric HR coatings and positive cylindrical lenses are available
