Spectrometer Prism Separates Light

Product Code : SCL-LAO-12077

Spectrometer Prism Separates Light (SKU SCL-LAO-12077) is a 32 mm equilateral prism of dense flint glass that spreads white or discharge-lamp light into its spectrum on a spectrometer prism table. It is meant for B.Sc. and engineering physics practicals and advanced senior-secondary demonstrations. Science Lab Supplies manufactures the prism at its Plot 448 unit in the HSIIDC Industrial Area, Saha, Ambala, India, and supplies schools, colleges, tender contractors and distributors straight from that unit.

Specifications

Each property of the flint glass spectrometer prism is listed separately in the table. In short, it is an equilateral prism with 32 mm faces in high-dispersion flint glass of nominal refractive index 1.6200 at 589.3 nm, polished on all three faces and chamfered at the edges.

Applications and Experiments for the Spectrometer Prism

Placed on the prism table of a spectrometer, the prism is turned until the spectrum reaches minimum deviation, and the angles are read from the vernier. Its flint glass spreads colours more widely than crown glass, which helps students separate close spectral lines.

• B.Sc. practical: refractive index from the angle of minimum deviation, μ = sin((A + Dm)/2) / sin(A/2), on a Laboratory Spectrometer.
• B.Sc. practical: dispersive power of the glass from red and violet readings, and checking Cauchy's relation.
• Observing emission lines from hydrogen, helium or sodium discharge tubes and comparing them with a grating spectrum from the Diffraction Gratings with Holder.
• Class 12: demonstrating dispersion of white light, with the larger Glass Prism (Equilateral, 50 × 50 mm) for comparison.

Handle the prism by its top and bottom surfaces, never the polished faces, and clean it only with an optical cloth.

Standard Scope of Supply

Each prism comes in a hard-shell protective presentation container with an anti-static velvet polishing wrap and a technical data card listing its wavelength dispersion indices. The spectrometer, discharge tubes and lamps are not included; they are separate items and can be added to the quotation.

Packing, MOQ and Lead Time

One prism or a set for every spectrometer in the department can be quoted. The quotation states packing, delivery time and price for your quantity, and spectrometers or gratings can be listed with it so the optics practical is priced as a whole.

Holding an Importer-Exporter Code, this science apparatus manufacturer in India can ship to buyers in Iraq, Nigeria, Kenya, Ghana, Ethiopia and Tanzania. Ask about it through the contact page, add it with other optics to the enquiry cart, or see the lab tender page if a college purchase goes to tender.

Frequently Asked Questions

Why flint glass instead of crown glass?
Flint glass has a higher refractive index, about 1.62 here, and stronger dispersion, so the colours of the spectrum spread further apart. Closely spaced lines are easier to separate and measure on the vernier.

Are all three faces polished?
Yes. All three faces are ground and polished, so light can enter from any orientation on the prism table. The edges carry fine chamfers that reduce chipping during adjustments.

Will it fit our spectrometer's prism table?
The prism is 32 mm high with 32 mm faces, a size made for standard spectrometer prism tables. If your table has unusual clamps, send its dimensions through the contact page before ordering.

Is this prism made by Science Lab Supplies?
Yes. As the manufacturer, Science Lab Supplies produces the prism in Saha, Ambala, India, and handles your quotation in-house, so the price and delivery details reflect its own production rather than a reseller's.
