Broadband Metallic Mirror

High reflectance
Variety of Sizes and Coating Options Available

Broadband metallic mirrors provide high reflectance for a particular wavelength region. Holmarc's broadband metallic mirrors make use of dielectric layers along with metallic coating to increase the reflectance for the required wavelength range.

We provide mirrors with enhanced aluminium, enhanced silver and protected gold coatings. Custom sizes and flatness are available as well.
