Abstract
A method and apparatus for determining the quality of an illuminating device, such as an elongated lamp, that is useable with an imaging device, such as a scanner. Electrical power is supplied to the lamp so that it emits a light beam. The light beam is then measured and a determination is made as to whether the emitted light of the lamp is within one or more predetermined values, which include overall brightness, stabilized output power, and profile flatness values.
