Broadband Dielectric Mirrors
Broadband dielectric mirrors are available in three different spectral ranges visible, NIR and IR regions. Its primary purpose is to redirect light to make optical systems compact in size. These are utilized in beam guiding with broadband reflection demanding applications in visible, NIR, and IR ranges. Wavelength Opto-Electronic offers broadband dielectric mirrors with a high degree of surface flatness, low scattering, and high reflectivity.
