Abstract
A photometer is provided with modular lighting units wherein each lighting unit includes one or more light emitters. A user may select a desired lighting unit and install it within a photometer base unit, and thereafter activate one or more of the emitters (which may emit light of different wavelengths) to illuminate a specimen. The light provided by the specimen in response can then be captured at a detector, and analyzed to provide an indication of the specimen's characteristics. Different lighting units may optionally include one or more input light adapters (filters or polarizers which modify the light provided by the emitter(s) to the specimen), and/or one or more output light adapters (filters or polarizers which modify the light provided by the specimen to the detector). Users may therefore select lighting units with emitters and light adapters which are particularly suited for detection/analysis of particular specimens and/or components therein.
