05 Dec 2014 Laser dichroic mirrors must have defect free surfaces and high damage threshold coatings. They are designed and manufactured for a specific task. Our laser dichroic mirrors are thin film stacks which form an edge filter on one face of the mirror and an anti-reflection coating on the other face. Reflectance is at least 99.5% for the reflected wavelength and transmittance is over 95% for the second wavelength. Both long-pass and short-pass versions are available.
These mirrors can be supplied for 45° or normal incidence. They are usually supplied on Corning7980 or Fused Silica substrates of λ/10 flatness and 10/5 surface quality and have a high laser damage threshold of > 10J/cm2 1064nm.
