Luke Gers - Optical Engineer and Program Manager for Land Based Telescopes

 "Cascade Optical has been a project saver many times over! When most other vendors are running behind schedule Cascade Optical has come through and beat expectations. Putting the project back on schedule. Quotes are always fast and efficient, usually less than 48 hour turn around with prototype designs. Excellent turn around time on coated optics from small 25mm diameters to large 550mm diameters.  From aspheric lenses, beam splitters, and high angle of incidence VPH gratings Cascade has done an excellent job at meeting or beating our tough specifications!"

Dr. Chunyu Zhao-President and Owner Of Arizona Optical Metrology

“I have been working with Cascade Optical Corporation for several years. I use them to coat my fragile optical elements that require low temperatures and extreme attention to detail. The spectral performance and quality of each and every coating run has been exemplary and delivery has been impeccable."

Dr. Chunyu Zhao earned a PhD in Optical Engineering from the University of Arizona, College  of Optical Sciences where he is currently an Associate Research Professor. His work is focused on designing and building interferometric systems for testing large aspheric optics, especially those systems using Computer Generated Holograms (CGH). Dr. Zhao co-founded Arizona Optical Metrology LLC and currently serves as the Chief Engineer. The CGHs are 2d gratings fabricated on fused silica substrates which need to be AR coated to eliminate ghost reflections in order to achieve super high measurement accuracy of the aspheric surfaces.
