ALLUXA Sirrus plasma physical vapour deposition (PVD) platform provides groundbreaking capability in extending the spectral optical coating performance. The next-generation PVD platform provides full spectral coverage from ultraviolet (200µm) to infrared (14µm). The proprietary process enables optical filters with steep edges, high transmission and deep blocking available while maintaining high-performance, precision wavelength control and extremely uniform coatings. The extended spectral performance is available on a variety of firm’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.
