Alluxa, Inc., a specialist in high-performance optical coatings and filters and thin-film deposition technologies, introduces a breakthrough 10.6 µm infrared (IR) notch filter with optical density > 4.0 (OD4). The innovative, high-layer-count IR optical coating is produced by utilizing Alluxa’s proprietary deposition capabilities that now deliver groundbreaking optical coating performance in the 8 µm to 12 µm spectral range. Alluxa will be at SPIE Photonics West, Feb. 4 – 6, 2020, Moscone Center, San Francisco, in booth #5183.
The new 10.6 µm notch filter is a leap forward in IR coating technology. It features hundreds of layers to achieve blocking of OD4 at the laser wavelength. The filter matches the theoretical design spectrum very closely.
