Hyland Optical Technologies Corporation is a privately held California Corporation based In Scotts Valley, California. The company acquired the assets of the Ealing Catalog in 2013. The Ealing Catalog offers a wide variety of research and industrial grade products that will help you design and build a better opto-mechanical system. We offer high precision optical components including bandpass filters, laser mirrors, fused silica lenses as well as selection of polarizing elements such as waveplates, beam splitters and sheet polarizers. The opto-mechnical mounts in the catalog are designed and manufactured with the engineer in mind. Ealing offers mounting systems such as rails, breadboards and optical tables. Mounting hardware such as rail carriers, post and post holders allow the use to deploy an array of component mounts for lenses and mirrors. We also offer single axis mechanical stages in several sizes that can be used with manual or motorized positions such as encoder drivers.
