Infrared Filters for Earth Atmospheric Satellites

What is it about?

Infrared filters have been developed to aid high-resolution monitoring of stratospheric and mesospheric temperature, trace chemical species, and geopotential height gradients in the Earth’s atmosphere.

Why is it important?

A method of combining the measured spectral characteristics of each filter and antireflection coating, together withthe spectral response of the other optical elements in the instrument, to obtain a predicted system throughput response is presented.

The design methods that are used to define the filter and coating spectral requirements, choice of filter materials, multilayer designs, and deposition techniques are discussed.
