title: Simple spectropolarimetric accessory for dual-wavelength spectrophotometers.
abstract: A simple spectropolarimetry accessory for the Aminco DW-2a spectrophotometer is described. It is useful in the wavelength range 414-671 nm (with slight modifications 200-800 nm) and gives a resolution in optical rotation better than 0.01 degree. The principle should be applicable to many other types of spectrophotometers.
