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 makes the raybox and its accessory set in Saha, Ambala, India, at Plot 448, HSIIDC Industrial Area, and its quotations go directly to schools, colleges, tender contractors and distributors.
Specifications
Lamp, lens, masks, filters and base size of the raybox each take a row below. In short, a 12 V, 10 W line-filament bulb sits under an adjustable lid that lets minimum light escape in unwanted directions, power enters through two 4 mm sockets, and the kit adds a 75 mm lens, two 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): reflection from a Plastic Mirror, 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. A 12 V supply such as the AC/DC Laboratory Power Supply, plus blocks, prisms and mirrors, can be added to the quotation.
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 power supply can be added to it for the same delivery.
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. An optics bench order can be outlined on the contact page, gathered in the enquiry cart, or prepared as a bid through 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?
Rayboxes with this accessory kit are manufactured by Science Lab Supplies at its Saha, Ambala factory in India, and the factory itself returns the quotation and packs the order.
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.
