TelAztec RAR Nano-Texture in 30cm Laser Window!

TelAztec’s novel plasma etching technology is capable of producing extremely low reflection levels from particularly demanding very large scale optics. ¬†RAR Nano-Texturing met the challenge of ultra-low reflection loss, zero-added surface absorption, and durability for the largest single commercial optic processed to date. ¬†The photo above shows Anthony Manni, CTO of TelAztec holding a massive, 12‚ÄĚ diameter, 1.5‚ÄĚ thick, RAR-L2 Nano-Textured fused silica window intended for a high power laser system. ¬†RAR performance and uniformity across the large window aperture is evident in the photo and in the measured total spectral reflection plot given below!
TelAztec has established a strong production track-record with over 50,000 RAR Nano-Textured optics delivered to commercial customers over the past 5 years.  Customers commonly ask questions about size limitations for RAR Nano-Texturing a single substrate, and about the number of optics that can fit into a single RAR Nano-Texturing run. 
TelAztec’s patented plasma etch process is defined by extremely short machine cycle times and excellent scalability; as a result the RAR Nano-Texturing process boasts production throughput and low costs equivalent ¬†or better than the largest commercial thin-film AR coating providers! ¬†Operating multiple 20cm and 30cm etch tools, TelAztec has demonstrated the ability to support high-volume production with excellent batch-to-batch repeatability and intra-batch uniformity.
