摘要：A conical illuminator for use in colorimetry, spectrophotometry, densitometryor sensitometry. In a preferred embodiment, light from a source such as a pulsed xenonlamp is integrated within an integrating chamber. The light source may be placed in asecond integrating chamber adjacent to the aforementioned integrating chamber.Alternatively, the lamp may be placed directly within the integrating chamber. The light isemitted through an exit port and conformed to a conical configuration, according to apre-selected standard, via an annular stop. An imaging optic relays the conformed lightuniformly onto a sample plane. The annular stop is placed at or near the tangential focallength of the imaging optic. The annular stop may be coated with a light absorbingcoating, or can be formed with a grooved or mirrored surface. Alternatively, in lieu of anintegrating chamber, a diffuser may be employed for homogenizing the light. Variousconfigurations of the imaging optic and annular stop are possible.
