INSTRUMENTS FOR ANALYZING SUBSTANCES BY DETERMINING THEIR RADIATION ABSORPTION CHARACTERISTICS

摘要

An instrument for analyzing substances by determining their radiation absorption characteristics when subjected to a beam of radiation, wherein, the optical components of the instrument are mounted on support members which lie in at least two intersecting planes. The support members may take the form of two flat plate members lying at an angle to one another in the manner of a pitched roof with the optical components supported on each flat member.
