Light intensity distribution measurement for optical densitometry or fluorescence measurement - has linear objective lens system, photoelectric sensor and illumination system all of equal length extending over whole width of sample.

摘要

A linear illumination system illuminates a strip-shaped partial surface of a transparent carrier. The illuminated region is fully projected onto the sensitive surface of a sensor (90) above the carrier. The optical projection system contains a number of linear objective lenses (80) with the same length as the sensor and illumination system. The lenses extend in parallel over the entire width of the specimen (50). ADVANTAGE - For measuring distribution of light intensity of a flat specimen on transparent carrier. Individual components are developed to produce mechanically simplified, more compact system with reduced problems of stray light screening.
