Filter holder

Product Code : SCL-OS-12817

The Filter Holder by Educational Instrument India is a practical physics laboratory accessory designed to hold optical filters securely during light, optics, colour, and ray experiments. It is commonly used with ray boxes, laser ray boxes, optical benches, light sources, and geometrical optics kits to position colour filters or optical filter plates in the path of light.

This holder helps students and teachers perform experiments related to colour mixing, light transmission, absorption, wavelength selection, and filter-based optics demonstrations. By keeping the filter stable and properly aligned, it improves the accuracy and clarity of classroom observations.

The Filter Holder is suitable for school laboratories, college physics labs, science classrooms, and training institutions. Its simple design, durable construction, and easy handling make it an essential accessory for optical experiments and laboratory demonstrations.
