This apparatus is a further development of that designed by Dr. Weld of Coe College. The principal change is that of using a photronic cell to measure the light intensity. The apparatus was designed especially for use in advanced optics courses. It can be operated easily by an advanced student and gives very accurate results with a minimum of simple adjustment. The photronic cell provides a quick, direct method of measuring the light. The student gets an introduction to photo-electricity through its use in the experiment. The apparatus provides a practical method of demonstrating the action of any kind of polarizer-analyzer combination.
