Metallic Optical Coatings

Low loss coatings for telecom wavelengths 

Single and dual band coatings
These anti-reflection coatings are specially designed to have low loss at telecom wavelengths. They are suitable for use on BK7 or UV Fused Silica optical components and they may also be applied to fiber ends. Single wavelength V-coatings are offered for the major telecom lines as well as dual band coatings which cover both the 1310-1319 nm band and the 1550 nm band. A single wavelength V-coat will provide reflectance less than 0.25% for 0°incidence or
0.5% for 45° incidence at the chosen wavelength. Dual wavelength coatings will approach the performance of V-coats for two selected wavelengths
