Angle Insensitive Coatings are highly desirable in the world of Optics today. In Astrophysics, the Astronomer would like to capture the entire field of view of observation without degradation or back reflections from any perspective at a single point in time. With regards to laser applications, the Optical Scientist would like to capture the entire cone angle of a beam. In a light deprived system, applying an angle insensitive coating over a detector cape is crucial when trying to collect as many photons as possible. Etalons allow a Scientist to study a single laser line of importance. This can be difficult if the object one is studying is moving. With angle insensitive coatings all these problem are resolved.
