Easily hold two 90-degree crossed polarizing filters in one hand without the need for clips or ring stands. Useful for understanding that some materials polarize light that passes through them and opens questions that lead to discussion of material density, internal reflection, and anywhere directional light is useful, like in fiber optics.

Additional Details

The Polaroid analyzer gives a convenient method for analyzing the polarization of light and stress in suitable materials. The handle holds two sheets of polarizing filter at 90 degrees enabling stress in sample materials (provided) to be viewed. A polaroid sheet acts like a “grid” and allows only light waves oscillating in one plane to pass through. If another polaroid sheet is placed in front of the first, and aligned in the same direction, the polarized light from the first will pass through the second since the waves are in the correct plane. If the second polaroid is rotated through 90 degrees, none of the waves will be able to pass and little light is transmitted. This system is known as “crossed polarizers” and is used in this apparatus. Some materials have the property of rotating the plane of polarization of light and when placed between the crossed polarizers, some of the light is allowed to pass. Furthermore, stresses in the material change the amount of rotation and this change is also dependent upon the wavelength of the light. Colored patterns are therefore produced which give information about the stresses in the material.
