Abstract
A spectro photometer deflects a measuring beam off its original axis to pass through a long sample, and returns the measuring beam to its final direction after passing through the sample. The sample is guided along a path which is clear of a reference beam of the spectro photometer. This arrangement permits double-beam measurement of long samples, with good signal-to-noise ratio. Deflection is accomplished using a plurality of mirrors.
