BFi OPTiLAS, Pan-European partner of Precision Photonics, has successfully developed broadband anti-reflection (BBAR) coatings for the 3-5 μm spectral range capable of extremely high temperature operation and survivability; recent results have demonstrated operational survivability to 1000º C!

Other examples of custom MWIR IBS (ion-beam sputtering) coatings include plate polarizers for 2.94 μm, narrowband AR coatings at 3.4 μm and dichroic mirrors with high reflectance at 2.94 μm and high transmittance at 1.5 μm.
