Prism Glass
Product Code : LSK-LAO-11141
Prism Glass (SKU LSK-LAO-11141) covers transparent optical glass prisms in two shapes: equilateral 60° prisms that disperse sunlight into its seven colours, and right-angle 45°/45°/90° prisms that turn light by reflection. They serve refraction, dispersion and reflection practicals in schools and colleges. Science Lab Supplies produces them at its factory, Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, for schools, colleges, tender contractors and distributors.
Specifications
Each listed shape, size and grade has its own row in the table below. In short, the equilateral prism comes in 38 mm and 50 mm sizes, each in Routine or Superior quality, while the right-angle prism comes in 38 mm and 50 mm, all made of transparent optical glass.

Applications and Experiments for the Glass Prism
Equilateral prisms are used to refract and disperse light and to find the angle of minimum deviation, while right-angle prisms show how total internal reflection turns a beam through 90° or 180°. Together they cover the prism topics on most physics lab equipment lists for Class 11 and 12 and for college optics.
- Class 10 science: tracing a ray through an equilateral prism with an Optics Experiment Parallax Pin and observing dispersion of white light.
- Class 12 and B.Sc. physics: measuring the angle of minimum deviation and refractive index on a Laboratory Spectrometer.
- Class 12 physics: total internal reflection in a right-angle prism, compared with ordinary reflection from a Plastic Mirror.
- Building a simple prism periscope or a light-reversing demonstration from two right-angle prisms.
Standard Scope of Supply
Prism Glass is supplied as individual prisms in the shape, size and grade you order: equilateral 38 mm or 50 mm in Routine or Superior quality, or right-angle 38 mm or 50 mm. Please list each version and its quantity, and the quotation will show them as separate lines.
Packing, MOQ and Lead Time
Quotations can cover one prism of a single type or a mixed set for every student group. Science Lab Supplies gives the packing, delivery time and price for that exact mix, and spectrometers, pins or glass slabs can be priced on the same quotation to complete an optics bench.
Holding an Importer-Exporter Code, Science Lab Supplies can ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa. Start with the contact page, add items to the enquiry cart, or consult the lab tender page for tender quotations.
Frequently Asked Questions
What is the difference between Routine and Superior Quality?
Both are equilateral optical glass prisms in 38 mm or 50 mm. Routine and Superior are the two grades listed for this prism; name the grade on your enquiry and the quotation will state it against each size and quantity.
What is the right-angle prism used for?
The 45°/45°/90° prism is used to show total internal reflection. Light entering one short face reflects inside the long face and leaves turned through 90°, the principle behind prism periscopes and binoculars.
Which size should a school order?
Both shapes come in 38 mm and 50 mm. The 50 mm size gives larger faces for ray tracing on paper, while a 38 mm prism takes less room on a spectrometer prism table; the two sizes can be mixed on one order.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The prisms are made at the company's own Saha, Ambala works, and enquiries are answered by the same team that produces them, with no trading layer.
