We have been able to create coatings that are extremely temperature resistant T>800ºC.
Our high temperature coating process enables our customers to enjoy the benefits of thin film filtration while simultaneously enduring a high temperature post process
Large Optical Filters are commonly coated at Cascade Optical Corporation. We frequently coat protected metal mirrors that are greater than 889mm in diameter. We also commonly coat various multi-layer dielectrics that have a diagonal of greater than 571mm across
Curved Surfaces: We coat Domes, Tubes, Aspheres, Polygones, and other non plano surfaces. We have more than 40 years of tooling that has pushed the limits of a "line of sight" deposition process
Patterned Coated Glass: With custom tooling of thin sheets of etched metal shims Cascade can produce sub- millimeter tolerances for intricate patterns and shapes. This includes custom coatings that are greater than 5μm thick
Due to the nature of a thin film structure, coatings will shift at angles of incidence greater than 10 degrees. But, with our technology we able to optimize each and every layer for desired optical filtration while simultaneously maintaining angle insensitivity
With our large chamber systems, we coat volume display glass, Large Telescope Optics, and are Semiconductor ready. We have prefabricated pocket tooling for 8, 6, and 4 Inch wafers. We also have in-house Mechanical Engineers ready to design a custom tool that will accommodate your unique optic
