Multispectral arrays have long been a key contributor to earth observation and remote sensing satellites Helping to reduce SWAP, increase resolution and overall performance. Previously much of the focus here was in the VIS & NIR wavelength regions. Leaving UV, SWIR, MWIR & LWIR wavelength to require discrete filtering. With superior capabilities across all wavelengths in design, deposition, sizing, assembly, LAS, ghosting, R%, stray light management, and channel to channel cross talk. Materion can offer MS arrays with superior performance from UV (as low as 220nm) through the LWIR (as high as 15.8um). This paper intends to summarize these capabilities and present the expanding demand for this technology.
