Visible/NIR (Broad Band Multilayer)

Broadband Anti-Reflection coatings substantially reduce surface reflectance over a broad spectral region. These coatings are well suited for the steeply curved surfaces of high numerical aperture lenses, or for applications in which it is necessary to vary the *angle of incidence.

The multilayer coating can reach higher transmissions for broadband wavelength make this different from the single layer MgF2 broadband antireflection coating.  This makes it ideal for a wide range of multi-wavelength laser and white light applications.

AR coating is preferred over MgF2 for visible applications. Other antireflection coatings include visible/near-infrared (VIS-NIR) broadband antireflection coating specially optimized to minimize reflections for visible and near-infrared wavelengths.

*Please note that the wavelength range and reflectivity of the coating change with the incident angle.
