Product Code : SCL-LAO-12071
Rectangular Optical Light Box (SKU SCL-LAO-12071) is a 12 V ray box that sends narrow beams from both ends at once, so two groups can trace reflection and refraction on paper. It serves secondary-school, first-year college optics benches. The box is made in the Science Lab Supplies factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and the company quotes it directly to schools, colleges, tender contractors and distributors.
Specifications
The rows below list every technical detail of this dual-ended ray box. In short, a 12 V 24 W bulb sits in a ventilated 170 x 90 x 60 mm die-cast aluminium housing, with a sliding collimating lens, slit and filter channels, and 4 mm safety sockets for an external low-voltage supply.

Applications and Experiments for the Rectangular Optical Light Box
The light box gives sharp, adjustable beams for ray-tracing practicals: students set the slit, slide the lens until the rays run parallel and mark the beam before and after a mirror, block or prism. That makes it core optics lab equipment for schools that teach reflection and refraction by drawing.
- Class 10 light: reflection from plane, concave and convex mirrors, for example the elements of the Optical Reflection Demonstration Kit.
- Class 10–12: refraction through rectangular, semicircular and triangular blocks, and dispersion in a Glass Prism (Equilateral, 50 × 50 mm).
- Class 12 ray optics: cylindrical lenses converging and diverging parallel rays, and Snell's law at a boundary.
- Colour work: red, green and blue beams from the filter tracks for mixing.
Set a bench supply such as the AC/DC Laboratory Power Supply to 12 V, and let the warm housing cool before changing the bulb or slits.
Standard Scope of Supply
Each unit comes with the 12 V bulb already fitted, a combined single and triple slit plate, a multi-slit comb plate with 5 or 7 slits, a red, green and blue filter set, and a manual with ray-tracing templates. The low-voltage power supply is not part of the set and can be quoted separately.
Packing, MOQ and Lead Time
Quotations can cover one light box or a full class quantity for an optics laboratory. Each sets out packing, delivery time and price for that number, and a bench power supply, glass blocks or prisms can go on the same quotation.
With an Importer-Exporter Code on record, Science Lab Supplies can ship to buyers in Qatar, Sri Lanka, Vietnam, Malaysia, Peru and Egypt. For prices, write to the team via the contact page; to bundle several items, use the enquiry cart; tender buyers will find the bidding route on the lab tender page.
Frequently Asked Questions
What power source does the light box need?
It runs from an external low-voltage 12 V AC/DC laboratory supply through the 4 mm insulated safety sockets. The supply is not included, so add one to the quotation if your laboratory lacks one.
How many beams can it project?
With the combined plate it gives a single beam or three beams; the multi-slit comb plate gives five or seven parallel rays. Both ends emit at once; a sliding shutter closes either aperture.
How are the beams made parallel?
Slide the internal collimating lens bracket backwards or forwards until the projected rays stop spreading and run parallel across the sheet. Moving it further gives divergent beams when an experiment calls for them.
Who manufactures this ray box?
Science Lab Supplies is the manufacturer and builds the light box in its own Ambala factory at Saha. Buyers deal with the production team directly, and quotations carry the factory's own packing and delivery terms.
