Every object emits heat in the form electromagnetic waves and sampling the energy radiated into space allows the measurement of the temperature of the object without ever having to touch it. The wavelength of the light emitted by the object depends on it‘s temperature, with hotter objects generating light at shorter wavelengths. The response of most detectors used to measure electromagnetic radiation is in some way wavelength dependent.
Thermal detectors have the widest wavelength response with the limiting factor being the transmission window used to protect the sensing element. Pyroelectric detectors are ideal for this application with high temperature stability, excellent signal to noise and low cost.
Laser Components is a world leading manufacturer of pyroelectric detectors. From our research and production facility in Florida we supply customers all over the world with these industrial grade thermal detectors. The devices are manufactured in standard TO style packages and have long expected lifetimes making them ideal for this fit and forget application.
