Optics Set OG1, Geometrical Optics
Product Code : SCL-PL-12301
Optics Set OG1, Geometrical Optics (SKU SCL-PL-12301) is a boxed set of optical components for 20 experiments on light rays, mirrors, refraction, lenses and colour. It suits secondary school and junior college optics lessons. Science Lab Supplies supplies the set from Ambala, India, and quotes it for schools, colleges, training institutes, tender contractors and distributors.
Specifications
The set is built around an experimental lamp with slit diaphragms, mirrors, optical bodies, a prism, lenses and colour filters, stored in a foam-lined case with a captive lid and hinged handle. The lids lock with a bayonet system so boxes can be stacked.

Applications and Experiments for the OG1 Geometrical Optics Set
The set covers the core of school ray optics in one box, from rays and beams through mirrors, refraction and total reflection to lenses and colour mixing. It suits the Class 10 light chapters, Class 12 ray optics, and first-year college demonstrations.
- Class 10 science: reflection at plane and concave mirrors, focal points and characteristic rays.
- Class 10 science: refraction, refractive index at the air/water interface, and focal points of lenses.
- Class 12 physics: total internal reflection, the total reflection prism and the optical fibre.
- Decomposition of white light, and additive and subtractive colour mixing.
Standard Scope of Supply
The set contains all the components, spare bulb and literature listed in the table above, packed in the foam-lined case. Not included: the low-voltage power supply, the 160 mm square with protractor and the compass, which can be quoted separately.
Packing, MOQ and Lead Time
Quotations can cover one OG1 set or several for student groups, each with packing, delivery time and price. The power supply and other optics lab equipment for schools can be quoted on the same document.
As a registered exporter holding an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. Enquire via the contact page or the enquiry cart; for institutional tenders, see the lab tender page.
Frequently Asked Questions
How many experiments does the OG1 set cover?
It covers twenty experiments in geometrical optics, from light rays and plane mirrors to refraction, total reflection, the optical fibre, lenses and colour mixing.
What is needed but not included?
A low-voltage power supply with dual digital display (6–12 V/5 A and 0–12 V DC, limited to 12 V), a square with protractor of 160 mm, and a compass.
How is the set stored?
In a case with a captive lid, hinged handle and pre-formed foam insert. The lids lock with a bayonet system, so several boxes can be stacked and carried together.
Who supplies the Optics Set OG1?
Science Lab Supplies, a physics instruments supplier in India, supplies it from Ambala and can quote it on its own or with the companion OW1 wave optics set.
