Abstract

A system uses a photometer that establishes an optical channel between a light emitter and a light detector. The photometer analyses a specimen while it occupies a well in a tray. A movable platform transports the tray to the optical channel for analysis and removes the tray from the optical channel after analysis. The system calibrates the movable platform to assure proper alignment between the specimen and the photometric apparatus used to analyzed the specimen. The system also calibrates the optical channel without use of an external reference.
