Ultra-wide broadband dielectric mirrors

Share this on social media:

To complement its wide range of high performance optical coatings, Laser Components is working alongside Omega Optical to provide ultra-wide broadband dielectric mirrors. With a more than 99.5 per cent average reflectivity over the 350nm-1,800nm spectral range, the ultra-wide series offers high performance with a uniformly high reflectivity over 0-30° and 30-50° angles of incidence. 

These mirrors are produced using a plasma-assisted reactive magnetron sputtering process, giving a high physical durability, and temperature and humidity stability. Custom coating and substrate designs are available, allowing for optimisation within a specific range or coating on convex or concave substrates.

Ultra-wide, broadband dielectric mirrors have many advantages in applications such as astronomy, beam steering, solar collectors, low-light applications and any other optical systems requiring high efficiency across a broad spectral range.
