Alluxa Introduces PVD Process With Extended Spectral Performance For Optical Filters From UV To IR

10 Mar 2022

Alluxa, Inc., introduces a capability in extending the spectral optical coating performance. The innovative, next-generation SIRRUS™ plasma physical vapor deposition (PVD) platform offers full spectral coverage from ultraviolet (200 μm) to infrared (14 μm). The proprietary process enables optical filters with the steepest edges, highest transmission, and deepest blocking available while maintaining high-performance, precision wavelength control, and extremely uniform coatings.

The extended spectral performance is available on a variety of Alluxa’s optical filters, including ultra-narrow bandpass filters, bandpass filters, dichroic, notch, and multiband filters. The UV to Mid-IR coatings can also be deposited on various substrate shapes and sizes and even on large format parts. Other SIRRUS PVD features include high-volume output, quick turn manufacturing of new designs, and very high layer counts that deliver the highest possible spectral performance.
