Datasheet: Absorption Correction Lamps

With integrating sphere photometry comes errors from self-absorption. Industry standards and Labsphere recommend applying absorption correction techniques for situations where the physical configuration and characteristics of the lamp or LED under test differ from the reference lamp. Self-absorption correction is critical, since the physical size and shape of SSL products and lamps under test are typically very different from the reference lamp size and shape. The use of an absorption correction lamp can correct for self absorption errors. With this in mind, Labsphere has developed the AUX-35 and 100 absorption correction lamps. These lamps assemblies are available to use for more demanding measurements results where self-absorption correction is required.
