Power and energy are often incorrectly substituted for one another. Radiant energy, such as that emitted by a Laser, is electro-magnetic energy, which is transferred by electromagnetic waves. A joule is the unit of radiant energy and is defined as 1 watt x second.
Power is the rate at which energy is produced.
High energy and high power apertures are intended to be used in the optical transfer assembly of a system using a powerful laser as a source. A practical example is the aperture within a spatial filter assembly. For Q-Switching applications, consider a highly reflective aperture disc surface and a very high melting temperature disc material. We will custom fabricate aperture mounts to comply with the parameters of your assembly environment. Molybdenum, Tungsten Aperature Dia.
