A dual-mode method and apparatus of selectively measuring samples in either a vessel or as a surface tension retained sample held between two opposing pedestals is introduced. In either configuration, such modes further contain optical paths from a source system through a small-volume or large-volume sample to a spectrometer based system. Such a system enables a user to measure samples with absorbances ranging from about 0.005 up to about 2.0 Absorbance Units for any given wavelength.

Dual sample mode spectrophotometer

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.
