In 1800, William Herschel published a series of papers describing experiments which led him to identify infra-red radiation, a form of radiation beyond the red end of the spectrum of visible light. Background to the experiment When visible light falls on a surface, some of it may be absorbed; the surface is warmed.

Sensing the Invisible: The Herschel Experiment Science Mission
WebHe experimented with different metals and polishing methods and made his first reflecting telescope in 1668. Newton was not the only astronomer to think of building a telescope with a mirror, but he was the first to produce a working reflecting telescope. WebIn 1845, William Parsons, 3rd Earl of Rosse, built a telescope at his estate, Birr Castle, in Ireland. Lord Rosse’s telescope with its 72-inch mirror was the largest in the world, surpassing our forty-foot. It was known as ‘The Leviathan of Parsontown’. By the time it was completed, William had died and I was 95 years old. http://www.observadores-cometas.com/Herschel/About%20William%20Herschel/About%20William%20Herschel/Biography/Who_was_Herschel.htm razor seafood
