How do Infrared Filters work?

The emission of Infrared wavelengths occurs naturally at all times of the day and year. However it is ‘invisible’ light that spans a very broad spectrum, so to make practical use of IR radiation we need to somehow detect, control and manipulate it to provide coherent data. Think of a simple kitchen sieve. We put our vegetables into...
