Unlock new possibilities in optical system design with Iridian’s Multi-Zone Filters (MZF), which deliver spatially varying spectral performance on a single substrate. Available as assembled, patterned, or hybrid solutions, MZFs can integrate multiple filter functions, including bandpass, long-pass, short-pass, notch, anti-reflection, and high-reflector coatings, across wavelengths ranging from UV to LWIR.

Designed for demanding applications such as multispectral imaging, spectroscopy, defense, and space applications, Iridian’s MZF technology enables compact, high-performance optical solutions with multiple spectral bands on a single device. Our advanced fabrication capabilities support complex custom layouts, ultra-small zone transitions down to 20 μm, and exceptional durability through proven hard-dielectric coating technology.

Whether through precision-patterned coatings or robust multi-zone assemblies, Iridian delivers reliable, high-performance filter solutions that help transform standard detectors into powerful multispectral imaging systems while meeting the most stringent environmental and reliability requirements.
