Infrared Optics

ARO offers near infrared coatings from 750-3000nm

Catalog Products

Our infrared optics cover a broad range of the most commonly required specifications in terms of wavelength, size, reflectivity, and angle of incidence. ARO’s Emax mirrors for Ti:Sapphire laser systems are known for providing excellent laser damage threshold performance. Our TFP polarizing beam splitters split light into two beams by transmitting p-pol and reflecting s-pol light. If you don’t find what you are looking for in our catalog, we can also readily produce optics customized in virtually every aspect, including size, shape, substrate material, surface specifications, and performance characteristics. ARO can select from E-beam, magnetron sputtering, IBS, and ion-assisted deposition coating techniques based on your environmental, laser damage threshold, and wavelength requirements.
