Abstract
271,824. Leitz, E., [Firm of]. May 31, 1926, [Convention date]. Polarizing-apparatus.-Polarimeters, for measuring the specific rotation of optically active substances, employing half-shade devices are fitted with one or more glass plates in combination with the half-shade devices. The inclination of these glass plates can be varied to compensate for the optical rotatory power of the substance under examination, and this inclination enables readings to be effected on a more open scale than if an analyzer or quartz wedge were rotated. The plane of incidence of the glass plate makes an angle of 45‹ or 135‹ with the bisecting line of the half-shade device. A quartz wedge may also be fitted, and is cut parallel to the optical axis. being arranged so that one plane of polarization in the wedge bisects the half-shade angle of the half-shade device.
