Couple of Polarizing Filters
Product Code : SCL-OS-12867
The Couple of Polarizing Filters by Educational Instrument is designed for teaching how polarized light behaves when it passes through one or two polarizing elements. When two filters are rotated relative to each other, students can observe changes in transmitted light intensity and understand the role of polarization angle.
This pair is useful in wave optics, geometrical optics, and light-transmission demonstrations. It can be used with a compatible light source, optical bench, filter holder, screen, ray optics kit, or polarizer-analyzer setup. Related Educational Instrument pages include Polarizer/Analyzer, Filter Holder, LED Light Source, and Geometrical Optics Kit with Laser Ray Box.

Applications / Uses
Demonstrating polarization of visible light.
Showing extinction when two polarizers are crossed.
Studying transmitted light intensity at different filter angles.
Introducing Malus’ Law in school and college physics labs.
Comparing polarized and unpolarized light behaviour.
Using filters with LED lamps, ray boxes, screens, and optical bench setups.
How to Use the Couple of Polarizing Filters
Place a light source on a stable table or optical bench.
Hold or mount the first polarizing filter in the path of the light beam.
Place the second polarizing filter after the first filter in the same light path.
Rotate the second filter slowly while observing the brightness on a screen or surface.
Note the angle where transmitted light is strongest and where it becomes weakest.
Use the observations to explain polarization direction, analyzer rotation, and Malus’ Law.
Remove the filters carefully and store them in a clean protective cover after use.
Safety note: Use the filters under teacher or laboratory instructor supervision. Do not use intense lasers or high-power light sources unless the setup is approved for safe classroom use.
Care & Maintenance
Handle the filters by the edges to avoid fingerprints on the optical surface.
Clean only with a soft, dry optical cloth.
Do not bend, scratch, or expose the filters to excessive heat.
Store both filters in a dry protective sleeve or laboratory cabinet.
