Polaroid Disc Mounted
Product Code : LSK-LAO-11153
Polaroid Disc Mounted (SKU LSK-LAO-11153) is a mounted polarising disc with a 2 inch (50 mm) clear aperture, sandwiched between protective glass and held in a high-impact plastic retaining ring. Used in pairs, the discs show how the transmission of light changes as one is rotated, and they reveal stress patterns in plastics, liquid crystals, glass and minerals placed between them. Science Lab Supplies manufactures the mounted disc at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, for schools, colleges, tender contractors and distributors who order direct.
Specifications
The table records every specification of the 50 mm mounted polarising disc. In short, a polarising disc with a 2 inch clear aperture is protected by glass on both faces and set in a high-impact plastic ring, so students can handle, rotate and stack the discs safely and easily.

Applications and Experiments for the Polaroid Disc Mounted
Two discs, one fixed as polariser and one turned as analyser, make polarisation visible: the light dims as the analyser turns and is darkest when the discs are crossed. A transparent plastic or mineral placed between crossed discs shows coloured stress or crystal patterns, linking wave optics with materials study.
- Class 12 wave optics: showing that light is a transverse wave by rotating one disc against another.
- B.Sc. practical: checking how transmitted intensity varies with the angle between polariser and analyser, using a beam from a Rectangular Optical Light Box.
- Photoelasticity: viewing stress patterns in a bent plastic ruler or set square between crossed discs.
- Examining liquid crystal displays, glass and mineral sections, with the discs mounted in line on an Optical Bench Ordinary Physics Lab.
Polarisation experiments need two discs, so order them in pairs; the quotation states the quantity per set.
Standard Scope of Supply
The item is the mounted polarising disc as described: 2 inch clear aperture, protective glass on both sides and a high-impact plastic retaining ring, 50 mm in size. Light sources, stands, an optical bench and test samples are not included and can be quoted as separate lines.
Packing, MOQ and Lead Time
You can request a single pair of discs for a demonstration or enough pairs for every group in a wave-optics practical. Each quotation from Science Lab Supplies covers packing, delivery time and price for the quantity, and companion light sources or benches can join the same quote.
With its Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Iraq, Nigeria, Kenya, Ghana, Ethiopia and Tanzania. Send polarisation questions to the team via the contact page, add discs to the enquiry cart for a written price, or read the lab tender page before a procurement round.
Frequently Asked Questions
What can be shown with the Polaroid Disc Mounted?
Placed in pairs, the discs demonstrate variable transmission of light as one is rotated, and they reveal stress patterns in plastics, liquid crystals, glass and minerals set between them.
Why is the polarising disc covered with glass?
The protective glass on each side shields the polarising disc from scratches and fingermarks, and the high-impact plastic ring around it lets students handle and rotate the discs safely without touching the optical surfaces.
How do these differ from the square polarizing filters?
The Polarizing Filters are linear polarisers mounted in 35 mm square frames for visible and near-infrared light, whereas these are round 50 mm discs with a 2 inch aperture in protective glass and plastic rings.
Does Science Lab Supplies produce these discs?
Yes, it produces them. The mounted discs are assembled by Science Lab Supplies in its own Saha, Ambala facility in India, and laboratories receive the quotation directly from the producer.
