Multispectral FIlters

Multispectral filters enable simultaneous detection of multiple wavelength bands by integrating several spectral filters into a single compact assembly. This technology replaces bulky filter wheels with streamlined, high-resolution filter arrays, offering enhanced spectral precision, faster data acquisition, and reduced system complexity. 

Revolutionizing earth observation, remote sensing, and space imaging, our advanced multispectral filter assemblies replace traditional filter wheels with multi-band filter arrays mounted directly above the focal plane. This design enables compact, efficient, and highly precise spectral filtering across ultraviolet (UV) to long-wave infrared (LWIR) wavelengths. 

High-Resolution Multispectral Performance

Our assemblies integrate up to 15 spectral bands within a single device, featuring ultra-fine pitch spacing of less than 0.080 mm center-to-center for exceptional spectral separation. Engineered for both cryogenic and room temperature operation, these space-qualified, flight-proven filters deliver spectral performance on par with conventional loose filters, ensuring reliability in the most demanding environments.

Precision Fabrication and Customization

Utilizing advanced fabrication techniques, Materion produces filter features as small as a few tens of microns, positioned with micron-level accuracy on a single substrate. Multiple filters with customizable shapes and sizes coexist on one substrate, tailored to specific sensor architectures. This flexibility supports complex sensor systems with optimized spectral fidelity across a broad wavelength range.

Proven Expertise in Multispectral Solutions

With over 40 years of optical manufacturing experience and a strong heritage in space applications, Materion leads in multispectral imaging technology development. Our ARRAYTEC™ product line combines cutting-edge capabilities with scalable, cost-effective solutions to meet evolving market needs.

Advanced Optical Coatings

Our multispectral optical coatings, deposited via plasma-assisted processes, offer low absorption and exceptional environmental stability. They provide sharp separation between reflected and transmitted wavelengths and can be precisely customized in spectral dimensions, angle of incidence, and size. This adaptability ensures optimized performance across UV to near-infrared (NIR) ranges for the most demanding sensor applications.
