  • Sputtered Thin-film Coatings

    By IDEX Health & Science

    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).

  • Notch Filters

    By IDEX Health & Science

    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
