Spectrogon manufactures optical interference filters, thin film coatings, and holographic diffraction gratings. The filters are used in several applications such as medical, process industry, thermal ...

Dichroic filters comprise thin, multilayered film coatings deposited on optical-grade glass. Advanced interference filters ...

Applying a well-known optical phenomenon called thin-film interference, a group of researchers at Harvard University has demonstrated the ability to "paint" ultra-thin coatings onto a rough ...

“Although for BAW and SAW filters, the important measurement is of crystallinity at the face itself.” Silicon photonics and quantum devices Silicon photonics has unique requirements in the area of ...

Dichroic filters comprise thin, multilayered film coatings deposited on optical-grade glass. Advanced interference filters have consecutive dielectric layers deposited on the optical glass or polymer ...
