Dielectric HR Mirror
Dielectric HR Mirror offers near total reflection, minimizing losses in nearly all optical systems. It has a high reflcetivity in a narrow band or broadband wavelength. Such dielectric HR mirror are widely use in projection optics systems, imaging, sensors or laser measurement systems.
Available either broadband or narrowband, they operate efficiently over 0¨C45¡ã angle of incidence: AOI=0¡ã, R>99.8%; AOI=45¡ã, R>99.5% (Rs>99.9%, Rp>99.2%).
