Quarter and Half Wave Plate Experiment

OBJECTIVES To study the effect of wave plates on polarized light Quarter wave plate Half wave plate PRINCIPLE Waveplates are optical devices that resolve a light wave into two orthogonal linear polarization components by producing a phase shift between them. The transmitted light may have a different type of polarization than the incident beam due to the induced phase difference. Commonly used retarders are quarter-wave plates and half-wave plates. The quarter-wave plate is used to convert a linearly polarized input beam into a circular (or elliptical) polarized beam and vice-versa. Half-wave plate rotates the plane of polarization of linearly polarized light that is input on it by twice the angle between its optical axis and the initial orientation of the linearly polarized light. KEY FEATURES Precise Optical Alignment: The optical alignment of the components is attained by the optical bench, the set-up time is faster and experimentation is easy. Digital Lux Meter: This enables the measurement of light intensity at various angles of reflection. The meter reads with a precision of 1 lux. Easy and accurate adjustments: The design of the setup helps in the easier rotation of wave plates without blocking the path of light. The least o count of 1 aid in accurate readings WHAT YOU NEED OB1 Optical Bench Set 0.8m 1 UP001 Upright 1 HA001 Light Source Holder 1 HA004 Polarizer Holder 1 HA006 Analyzer Holder 1 HA510 Light Sensor Holder 1 DP1 Data Processor 1 PH61022D/2 Power Supply for Light Source 1 HA030 Quarter Wave Plate Holder 1 HA031 Half Wave Plate Holder 1 Complete Equipment Set with Instruction Manual from catalogue.
