  • Apparatus for measuring characteristics of optical angle
    Patent number: 6636308
    Abstract: The present invention relates to a light scattering intensity measuring apparatus capable of measuring, as a function of the scattering angle, the intensity of the light scattered from a sample. This apparatus comprises an ellipsoidal mirror 24 for reflecting and condensing the scattered light from a sample 23; an image-forming lens 25 disposed at the condensing point of light reflected by the ellipsoidal mirror 24 for forming, on a camera face, the image formed on the surface of the reflection mirror 24; and a camera 26 for recording the image formed by the image-forming lens 25. The scattered light in a wide angle range can be detected in a very short period of time (FIG. 1).
