Product Description

Overview:
Dielectric Broadband Mirrors provide an optimized performance at broad wavelength range and wide angle of incidence (AOI). These multilayer coating stacks helps to achieve the highest possible reflectivity at broad spectrum region at normal to 45 degrees incidence. Therefore, they are ideal for beam steering or reflection applications utilizing multiple laser sources.

Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques. High reflectivity greater than 99% dielectric coatings in the range of 0.19 - 20 µm are available. They are significantly better than that of metal coated mirrors, and increases system performance by minimizing energy loss.
