Light Meters are used to measure the light output of an illumination source for a number of optical applications. Light Meters are measurement devices that feature photodiodes to determine the level of light transmitted from a source. Light Meters possess simple, easy to read screens upon which measurements are displayed in one or more photometric units. Most Light Meters possess traceable NIST certification for proof of accuracy.
