Raybox with Accessories
Product Code : LSK-PL-10318
Raybox with Accessories (SKU LSK-PL-10318) is a 12 V ray box with a plano-convex lens, slit masks and colour filters that produces single rays or divergent, convergent and parallel beams for experiments with blocks, prisms and mirrors. It serves as optics lab equipment for schools and college ray-optics practicals. Science Lab Supplies manufactures it at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, supplying schools, colleges, tender contractors and distributors directly from there.
Specifications
A 12 V, 10 W line-filament bulb sits under an adjustable lid designed so that minimum light escapes in unwanted directions. Power, 12 V AC or DC, connects through two 4 mm sockets. The accessories include a 75 mm plano-convex lens, slit masks and eight filters.

Applications and Experiments for the Raybox
Without the lens the raybox gives a single ray; with the lens in place, plane face towards the lamp, and a two-slit, three-slit or broad-slit mask, moving the lamp relative to the lens makes the beam divergent, convergent or parallel. Blocks, prisms and mirrors then cover reflection and refraction.
- NCERT Class 10 science (Light): mirrors, glass-slab refraction and lens ray paths.
- Class 12 physics (Ray Optics): refraction through a prism and total internal reflection.
- Colour lessons: coloured beams from the filters in a darkened room.
Standard Scope of Supply
The set comprises the raybox with its 12 V, 10 W bulb, a 75 mm plano-convex lens, two plastic slit masks, seven coloured filters and one tri-colour filter in 50 x 50 mm frames. The 12 V AC or DC supply and the blocks, prisms and mirrors are separate items.
Packing, MOQ and Lead Time
Request one raybox for demonstration or enough for each optics group in the class. The quotation shows packing, delivery time and price for that quantity, and glass blocks, prisms, mirrors or a low-voltage supply can be added.
Science Lab Supplies is registered as an exporter with an Importer-Exporter Code and is able to ship to buyers in Nigeria, Kenya, Ghana, Ethiopia, Tanzania and Uganda. Start an enquiry on the contact page, collect optics items in the enquiry cart, or read the lab tender page.
Frequently Asked Questions
What power supply does the raybox need?
It needs 12 V AC or DC, connected to the two 4 mm sockets on the raybox. The lamp is a 12 V, 10 W line-filament bulb, 43 mm long.
How do I get a parallel beam?
Insert the plano-convex lens with its plane face towards the light source, fit a slit mask, and adjust the position of the lamp relative to the lens until the emerging rays are parallel.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer; the raybox is produced at its Saha, Ambala factory in India, and buyers receive the quotation from that factory.
Why are the coloured beams faint in a bright room?
The filters do produce coloured beams, but external light levels have to be reduced for them to show well. Dim the room lights or draw the blinds during colour experiments.
