👉 A bolometer is a type of electronic device that measures electrical fields or magnetic fields. It consists of a series of metal plates, often made of copper or silver, which are placed in parallel to form an array. The plates are usually covered with a conducting material such as gold or tungsten, and the surface of each plate is coated with a layer of dielectric medium (such as a permanganate solution) that allows the fields produced by the plates to be measured. The field strength at
