APPARATUS FOR MEASURING CHARACTERISTICS OF OPTICAL ANGLE

摘要

An apparatus for measuring the intensity of scattered light from a sample in terms of a function of a scattering angle, comprising an ellipsoidal mirror (24) for reflecting scattered light from a sample (23) and concentrating the same, an imaging lens (25) disposed at a concentration point of the reflected light from the ellipsoidal mirror (24) and forming an image of the image formed on the surface of the ellipsoidal mirror (24), and a camera (26) for recording the image formed by the imaging lens (25), whereby the detection of scattered light in a range of a wide angle in a very short period of time. <IMAGE>
