Abstract
An apparatus for measuring light scattered at various angles from a sample of molecules in solution, having a plurality of conical reflectors mounted on a turret assembly. The turret assembly is positioned in a temperature controlled tank. A laser beam is directed through the tank with the polymer sample being positioned within one of said reflectors in the path of the laser beam. Light scattered at a particular angle is collected and directed to a detector. The unscattered light is also directed toward the detector along a second path. A light chopper is provided to alternately supply scattered light and the unscattered light beam to the detector. The laser beam path through the sample can be reversed to provide a measure of back scattered light. Each of the conical mirrors may be selectively locked in position for positioning the polymer sample in the light path.
