For space and other harsh environments, Iridian&#8217;s light absorbers can be designed and fabricated for either a narrow or broad wavelength ranges between 400-2200 nm. They use hard dielectric coatings with excellent durability. In addition, our light absorbers can be shipped with an adhesive-backed surface for easy application to different types of surfaces and can be cut into different shapes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Earth-Orbit\/Lunar communications Due to their excellent uniformity\u00a0and transmission characteristics along with their inherent reliability and durability, Iridian&#8217;s standard\u00a0telecom filters have been used\u00a0for earth-lunar communication for NASA&#8217;s Lunar Laser Communication Demonstration (LLCD) associated with the LADEE (Lunar Atmosphere and Dust Environment Explorer) project.
