BroadBeam™ Ultra-Broadband High Reflector Mirrors

Newport's BroadBeam™ Ultra-Broadband Mirrors provide high reflectivity over the broadest wavelength range in the industry for a standard mirror. Typical broadband mirrors with high reflectivity may cover the UV to visible or visible to NIR regions. But only the BroadBeam Ultra-Broadband Mirrors offer 97.5% average reflectivity from UV to NIR, making it the most versatile mirror available. Additionally, the metal-dielectric hybrid coating maintains reflectivity performance from 0° to 50° angle of incidence.

Features

UV Fused Silica Substrates

Fused Silica is synthetic amorphous silicon dioxide of extremely high purity. This non-crystalline, colorless silica glass combines a low content of inclusions with high refractive index homogeneity, a very low thermal expansion coefficient, and excellent transmittance in the wavelength regime from UV to NIR. As a result, these mirrors will perform better with temperature fluctuations and is ideal for high-energy laser applications due to its high energy damage threshold. For more information, please see our Optical Materials technical note.

Extremely Broad Wavelength Range With High Reflectivity

Broadbeam mirrors feature unprecedented specifications at an incredible value. These mirrors feature Newport’s proprietary metal-dielectric hybrid coating which provides exceptional reflectivity performance R_avg>97.5% over a very large wavelength range 350 - 1100 nm, 0 - 50 ͦ angle of incidence for both S and P polarizations. Because of the very broad wavelength range and high reflectivity efficiency, the mirror can be used with many different laser wavelengths and can easily replace all of the mirrors in your current system.

More Durable Metal Dielectric Coatings

In addition to the high reflectivity across the ultra-broadband wavelength range, the Broadbeam mirrors also feature a more durable coating compared to the traditional metallic mirrors. Typically metallic coatings suffer from more rapid degradation over time when compared to dielectrics. Broadband mirrors use a metal dielectric hybrid coating that is more resistant to humidity, thermal changes, abrasion and salt exposure, providing long-term value for your applications.
