Diffraction and Interference Study Kit - Teacher's Demonstration Model
Product Code : SCL-PL-12300
Diffraction and Interference Study Kit - Teacher's Demonstration Model (SKU SCL-PL-12300) is a laser-based teacher’s set for demonstrating diffraction and Young’s interference, which also includes a multibeam laser and a magnetic eye model. It suits Class 10 and Class 12 optics teaching. Schools, colleges, training institutes, tender contractors and distributors can obtain the kit through Science Lab Supplies in Ambala, India, which quotes it with matching optics apparatus.
Specifications
Each part of this teacher’s kit is itemised below. In short, a 1 mW, 650 nm class II red laser with a Fresnel lens makes a plane beam for the slit and hole tokens, a multibeam laser adds four red beams and one green beam, and everything stores in a foam-lined case.

Applications and Experiments for the Diffraction and Interference Kit
The kit lets a teacher project diffraction and interference patterns large enough for a class to see, and trace rays through lenses with the multibeam laser and magnetic eye. It supports Class 12 wave optics, Class 10 lessons on the human eye, and undergraduate demonstrations.
- Class 12 physics: Young’s double-slit interference.
- Class 12 physics: single-slit diffraction and patterns from multiple slits and holes, before precise angle work on a Laboratory Spectrometer.
- Class 10 science: the human eye, image formation and correction of vision defects with the magnetic eye kit, beside the five-times model Eye in Orbit, Magnified 5 Times, in 7 Parts.
Standard Scope of Supply
The kit contains the 650 nm red laser with its 5 V supply, rod, magnetic base plate and Fresnel lens; the three ringed slit and hole tokens; the red and green multibeam laser with its 4.5 V supply; the magnetic eye kit; red-laser over-glasses; and the foam-lined case.
Packing, MOQ and Lead Time
A quotation can be made for one teacher’s kit or several for different schools, stating packing, delivery time and price for that quantity. Gratings, polarizing filters and other optics lab equipment for schools can go on the same quotation, so a complete wave-optics corner is priced in one document.

Frequently Asked Questions
What lasers are in the kit?
Two class II lasers: a 1 mW, 650 nm red laser, and a multibeam laser with four 650 nm red beams and one 535 nm green beam, selected by a switch.
What safety precautions apply to the lasers?
Never view a beam directly or aim it at anyone’s eyes. Over-glasses for red laser protection are included, and the kit is meant for teacher-led demonstrations under supervision.
What is the magnetic eye kit for?
Its five magnetic lenses and erasable A3 plate of the human eye let a teacher show how the eye forms images and how lenses correct vision defects.
Who supplies the Diffraction and Interference Study Kit?
The kit is quoted from Ambala by Science Lab Supplies, a physics instruments supplier in India, either on its own or together with gratings, filters and other optics apparatus for school and tender orders.
