(Alluxa: Santa Rosa, CA) -- Alluxa, a global leader in high-performance optical coatings and filters and thin-film deposition technologies, has introduced a groundbreaking capability in extending spectral optical-coating performance. The SIRRUS plasma physical vapor deposition (PVD) platform now 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 uniform coatings.

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