Dielectric mirrors offer higher reflectivity over a broad spectral range of up to several hundred nanometers. Their coating is more durable making them easier to clean and more resistant to laser damage.
Metallic coated mirrors are good general-purpose mirrors because they can be used over a very broad spectral range from 450 nm to 12 µm. However, their softer coating makes them more susceptible to damage.
Our ultrafast mirrors can be used with ultrashort pulse lasers like the Spitfire or Mai Tai to route and focus the beam.
