Product Announcement from Andover Corporation
Image quality filters are ideal for applications that require high resolution, such as astronomical observations, video monitoring systems, high-resolution photography, and other imaging applications. To meet these demanding requirements, Andover Corporation has developed a line of custom Image Quality filters.
Our image quality filters utilize high-quality optical glass, ground and polished to 1/4 wave transmitted wavefront, and better than 30 arc seconds parallel. If necessary, a higher degree of optical quality is available for more critical applications. To prevent fringe patterns and multiple images, all coatings are deposited onto a single internal surface and all exterior surfaces are broadband anti-reflection coated for an average reflection of <=0.5%
