A ray box turns a bulb into thin, well-defined beams that students can trace on paper, the foundation of ray optics. With a mirror, glass block or prism placed in the beam, pupils measure angles of incidence, reflection and refraction, find the critical angle and see how lenses bring rays to a focus. Only a minimum of accessories is needed to cover a wide range of optics experiments, which makes the ray box a core item of optics lab equipment.
Because two openings can be used at once, one box can serve two groups working on opposite sides, reducing the number of units a class needs. Run it from a separate 12 V supply, let the housing cool before changing the bulb, and dim the room lights slightly for the sharpest rays. The blanking plates close any opening that is not in use so stray light does not disturb the neighbouring group.
Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies the Raybox, 12V from Ambala, Haryana, India. The company sources the ray box with its standard accessories and can quote the power supply, slit plates and optical blocks that go with it, so a school can equip an optics practical from one enquiry. Schools, colleges, dealers and importers can contact us directly. Our company profile has more about ScienceLab.

What comes with the Raybox, 12V?
The Raybox, 12V is supplied with a 2 m cable fitted with two 4 mm plugs, a 12 V, 24 W B15 bulb, a bulb holder, a slit plate, aluminium blanking plates and an instruction manual. A power supply is not included.
Does the Raybox, 12V include a power supply?
No. The Raybox, 12V does not include a power supply. It needs a 12 V source connected through its 2 m cable with two 4 mm plugs, and a suitable low-voltage laboratory power supply can be quoted with it on request.
How many groups can use one Raybox, 12V?
The Raybox, 12V has three openings, and two of them can be used simultaneously by two sets of pupils. That lets one ray box serve two groups at once during reflection and refraction practicals.
How does the Raybox, 12V produce converging and diverging rays?
The front opening of the Raybox, 12V has seven grooves for accessories and lenses. Used with a biconvex cylindrical lens of 75 mm focal length, the slit plate gives divergent or convergent rays, so students can study lenses and focal points.
What bulb does the Raybox, 12V use?
The Raybox, 12V uses a 12 V, 24 W bulb with a B15 fitting, held in the supplied bulb holder. Keeping spare bulbs of the same rating on hand avoids lost lesson time if a bulb fails.
Who supplies the Raybox, 12V?
The Raybox, 12V is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources the ray box with its standard accessories and quotes it to schools, colleges, dealers and importers in India and international markets.
