OBJECTIVES

Measurement of Brewster’s angle for a given dielectric dispersive medium.

PRINCIPLE

When un-polarized light is incident on the surface of a dielectric (such as a glass), at a certain angle of incidence the reflected light is completely plane-polarized. This phenomenon was discovered by Sir David Brewster and, thus, the specific angle is called Brewster’s angle or polarization angle. Also, from the experiment, it can be confirmed that the reflected ray and the refracted ray are 90° apart when the incident angle is set at Brewster’s angle.

KEY FEATURES

Rotating Table: A simple, smooth, and compact rotating table. The rotating table used is extremely smooth to operate. It is a single assembly that holds a glass sample, analyzer, and light sensor, thus minimizing the size of the whole equipment. Smooth rotation makes measurement continuous and accurate.
Light Sensor: This enables the measurement of light intensity at various angles of reflection. The meter reads with a precision of 1 lux. The Lux meter helps obtain a continuous smooth curve of angle vs intensity and determines the Brewster angle much more accurately than the manual method.
