Abstract

An optical meter includes a force member to receive a force and a reflector disposed on the force member to receive radiation and to communicate a pressure of the radiation to the force member. The reflector includes a reflective surface, and the force member is configured to be displaced in response to receiving the force comprising the pressure. The optical meter is configured to measure a power of the radiation, an energy of the radiation, or a combination thereof based on the pressure. A process for measuring a property of radiation includes receiving radiation by the reflector, reflecting radiation from the reflective surface, communicating a pressure from the reflector to the force member, and displacing the force member.
