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.

Perspectives

Dr Gary J Hawkins
University of Reading

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.
