A multifunctional spectroscopic method under a polarizing microscope has been introduced. The polarizing microscope spectrophotometer is an assembled form that consits of a standard polarizing microscope attached with epi-illuminators (Hg or Xe or YAG), monochromaters, photodetection systems (photo-multiplier with Lockin amplifier or Boxcar digital processor, or diode array optical multi-channel analyzer) and a microcomputer. However it is restricted to the visible light region. Some effectiveness of this system have been demonstrated: Weak pleochroism in the absorption spectra and enhanced photo-luminescences originated from the same center as occur in the absorption are sensitively detected in zircon. Absorptiometry of ion exchange resin phase absorbing Cr6+ ions as colored species from aquious solution is successfully performed with sensitivity in two orders of higher magnitude than a conventional method.
