What is The Difference Between Visible Light and Heat Radiation
(OP)
What is the difference between visible light, invisible light, and radiation that causes a perceptible feeling of heat? Thanks, =TB





RE: What is The Difference Between Visible Light and Heat Radiation
What would be some techniques, if there are any, to reduce heat radiation from a with no or minimal attenuation of visible light as from the sun or a lamp.
Are there any particular types of glass perhaps, etc.?
Would a water cooled glass jacket or lens have an effect on reducing radiation heat from a lamp, or would this act only as a convective or conductive heat sink?

How about starting with a more efficient lamp (less heat produced)? LEDs should be pretty cool, if you can get enough light out of 'em.
Digital cameras use an IR-blocking filter, which may or may not provide some of the effect you're looking for. It's my understanding that blocking the IR gives a better color balance, and prevents seeing through clothing.

Near infrared and infrared are generally attributed to sensed heat, although rattlesnakes supposedly are able to either "see" or direction find warm bodies.
If you look in Edmund Scientific's catalog, there are warm and cold filters. The warm filter is designed to block non-visible wavelengths in projectors and the like.
