High reflectance coatings for telecom wavelengths 

Single wavelength and broadband reflectors

These high reflectance coatings are specially designed to have low loss at telecom wavelengths. Single wavelength HR coatings provide in excess of 99.8% reflectance of s-polarization and typically 99% reflectance of p-polarization at 45° incidence for the design wavelength. Broadband coatings are also offered for the major telecom bands and these provide over 99% average reflectance over a wavelength range from 1310 to 1550 nm.
