Choose the metal ray box when you want a metal, low-voltage lamp house with a slit plate and room for a cylindrical lens, and plan to add your own lenses and filters. Buyers who want the optics supplied in the same order can choose the ray box with optical kit, and the kit model runs from the mains.
What Is the Metal Ray Box Used For?
Light from the lamp passes through the slit plate in the front grooves: the single slit gives one narrow ray and the triple slit gives three. A cylindrical lens in the second groove can make the rays parallel or bring them together, so students can show three parallel rays meeting at the focus of a convex lens, spreading out from a concave lens, and reflecting from plane and curved mirrors. Placing a colour filter in front of the beam gives coloured rays for lessons on how filters and colours work. The box suits the light chapters of class 10 science, ray optics in class 12 physics and introductory college optics.
Run the 12 V lamp from a suitable low-voltage supply, not directly from the mains, and connect it with the banana plugs on the flex. The finned sides help the lamp house shed heat, but it still warms up in use: let it cool before touching the lamp or changing slits, and darken the room for the sharpest rays.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; class sets are usually one ray box per group.
- Power supply — add a power pack or battery eliminator if your lab has no 12 V supply, and ask JLab for the lamp wattage so the supply can be matched.
- Optics and filters — confirm whether you need the cylindrical lens, lens sets and colour filters, and add them to the same enquiry.
- Spare lamps — ask for spare 12 V lamps in the same enquiry.
Frequently Asked Questions
What is a metal ray box used for?
It produces narrow rays and parallel beams of light for optics experiments — reflection, refraction, lenses and coloured light with filters.
What power does it need?
The light source is a 12 V lamp, so it runs from a 12 V supply such as a lab power pack. The lamp wattage is not stated in the listing; ask JLab so the supply current can be matched.
Which slits are included?
It comes complete with a metal plate that has single and triple slits. The single slit gives one ray and the triple slit gives three parallel rays.
Are the lenses and colour filters included?
The listing names the slit plate as supplied and describes grooves for a cylindrical lens; lens sets and filters are used with the box. Ask JLab to confirm which optics are included in your quotation.
Why is the lamp house finned?
The extended sides are finned on the outside to dissipate the heat of the lamp, and the lamp house is ventilated, so the box stays cooler during long practicals.
Who manufactures this ray box?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics and optics apparatus manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The metal ray box is fabricated at JLab’s own works, not bought from a trader, so schools, colleges, dealers and importers buy it factory-direct, every box is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region, for example Namibia in Southern Africa, Togo in West Africa, Cameroon in Central Africa, Norway in Northern Europe and Morocco in North Africa. Tender buyers can find details on the JLab lab tenders page.
