Multi-zone Filters
The ability to offer spatially varying spectral performance on a single substrate can have many advantages for optical designers. Iridian offers both assembled multi-zone filter arrays and patterned multi-zone optical filters (sometimes referred to as multi-spectral filters (MSF)) to address these growing needs. Features of Iridian’s MZF offerings include:

Filter types:

Long-pass or short-pass filters (LPFs/SPFs)

Bandpass filters (BPFs)

Notch filters

Black absorbing coatings

Anti-reflection coatings (ARs)

High-reflectors (HR)

Wavelength range:

UV (300nm) to the long-wave infrared (LWIR 10 um)

Customization for size, spectral performance, and lay-out (number and size of zones)
