A SPECTROMETRY PHOTOMETER

摘要

The spectrophotometer comprises a light source(11) for emitting a beam of light, optical filters(F1)(F2) for receiving the light beam from lenses(12)(12,) and mirrors(13)(13') to produce monochromatic light, two integrating spheres(14)(14') for receiving light to produce the sample light beam, photoelectric conversion sensors for producing electric signals which are processed by a computer. The position of optical filters(F1)(F6) can be changed to the position of filters(F2)(F7). The required time to measure the light of the specimen can be reduced to 1/2 of the required time in conventional method by using two integrating spheres.
