  • Spectrophotometric method and apparatus
    Patent number: 4718762
    Abstract: A two-beam spectrophotometer comprising a monochromator and a beam splitter is provided. In addition to being inclined to the optical axis by an angle .alpha./2 lying in the optical plane, the beam splitter is inclined to the direction perpendicular to the optical plane, so that the reference beam is deflected out of the optical plane by an angle .beta.. This improves the spectral intensity distribution.A spectrophotometric method employing this apparatus is also provided.
