Polarizing Filters
Product Code : SCL-PL-12408
Polarizing Filters (SKU SCL-PL-12408) are linear polarizers mounted in 35 mm square frames, suitable for visible (VIS) and near-infrared (NIR) light. They let physics students produce and analyse plane-polarized light, check Malus's law and see how crossed polarizers block light. Science Lab Supplies manufactures the framed filters at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and supplies them directly to schools, colleges, tender contractors and distributors.
Specifications
Each filter is a linear polarizer held in a 35 mm square frame, which makes it simple to place in a holder or on an optical bench and to rotate against a second filter. The filters work across the visible range and into the near infrared, covering classroom demonstrations as well as near-infrared work.

Applications and Experiments for the Polarizing Filters
A pair of linear polarizers shows that light is a transverse wave. With one filter as polarizer and the other as analyser, rotating the analyser dims the light and blocks it at the crossed position, which leads on to Malus's law and to the polarization of reflected and scattered light.
- Class 12 physics (NCERT wave optics): polarization of light, polarizer and analyser.
- B.Sc. optics practicals: verifying Malus's law with a light source and detector.
- Demonstrating the reduction of glare from reflected light by polarization.
Standard Scope of Supply
The filters are supplied as linear polarizing filters mounted in 35 mm square frames, and the quantity per set is confirmed on the quotation. A light source, holders and a light detector are not included and can be added to the same quotation for a complete polarization set-up.
Packing, MOQ and Lead Time
Request a quotation for a single set of filters or for a whole optics laboratory, and Science Lab Supplies lists the packing, delivery time and price for that number. Light sources, holders and other optics lab equipment for schools can be added so that the polarization bench is priced together.
Science Lab Supplies can ship to buyers in Nigeria, Kenya, Ghana, Ethiopia, Tanzania and Uganda, as a registered exporter holding an Importer-Exporter Code. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU). The contact page, the enquiry cart and the lab tender page are three ways to start an enquiry.
Frequently Asked Questions
What wavelengths do the filters cover?
The filters are suitable for visible (VIS) and near-infrared (NIR) light, so they can be used with ordinary lamps and sources in the visible range as well as for near-infrared work.
How are two polarizing filters used together?
One filter polarizes the light and the second acts as an analyser. As the analyser is rotated, the transmitted brightness changes, reaching a minimum when the two filters are crossed at 90 degrees.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is a manufacturer rather than a trader. The framed filters are produced at its factory in Saha, Ambala, India, and quotations are handled by the factory team directly.
Are these filters meant for cameras?
No. They are laboratory polarizing filters in 35 mm square frames for physics optics experiments, intended for use on a bench with a light source rather than fitted to a camera lens.
