Apparatus for storing and visibly comparing the optical properties of minature samples
Abstract
Abstract Apparatus for storing a plurality of samples having known optical properties and for displaying and samples in a manner wherein the latter may be readily compared with an unknown sample for matching color or other optical properties of the latter comprises a flexible, elongated carrier tape upon which known microsamples are mounted. The tape is fed to a viewing station at which a magnifier or microscope is utilized to view the known samples simultaneously with an unknown sample which is disposed in a fixed position in the viewing station. Indicia means on the carrier tape, and associated with each known sample is also located within the viewing station, so that when the carrier tape is moved until a known sample matches the unknown sample, the indicia means, viewed through the magnifier, identifies the color or other optical properties of the matched samples.
