Optical thin-film coatings can be deposited by a variety of methods. Traditionally the most popular methods for depositing multilayer coatings – required for higher-performance mirrors and filters – include thermal and electron-beam (e-beam) evaporation and ion-assisted e-beam evaporation (IAD).

Optical Density – or OD, as it is commonly called – is a convenient tool to describe the transmission of light through a highly blocking optical filter (when the transmission is extremely small). Learn More

Notch filters are ideal for applications that require nearly complete rejection of a laser line while passing as much non-laser light as possible. The main drawback of standard thin-film notch filters has been a limited passband range due to the fundamental and higher-harmonic spectral stop bands. Learn More

The Semrock MaxLine and RazorEdge U-grade optical filters make an ideal filter pair for applications like Raman spectroscopy – they fit together like hand-in-glove. Learn More

Due to limitations of standard metrology techniques, the measured spectral characteristics of thin-film interference filters are frequently not determined accurately, especially when there are steep and deep edges.
