Rotatable Disc Set
Product Code : JA-LOE-7978
The Rotatable Disc Set (SKU JA-LOE-7978) is a complete set for reflection and refraction experiments in which the angles are read from a 230 mm disc divided into single degrees. This rotatable disc set with acrylic optical blocks includes a 12 V, 24 W lamp house that turns around the disc, a slit disc giving one to four rays, an adjustable lens, and magnet-backed acrylic blocks and 50 mm reflection elements, so a student group can work through several light experiments at one station.
Specifications
The set is built around a 230 mm diameter disc on a stable base, graduated from 0 to 360° at 1° intervals with a centre mark, and a 12 V, 24 W lamp house; the disc and the lamp house can each be rotated and held in any position.

Experiments with the rotatable disc set
The set is used for bench optics where students need quick, repeatable angle readings: they place a magnetic block at the centre of the disc, turn the disc or the lamp house and read the angles of incidence, reflection and refraction directly.
- Laws of reflection using the 50 mm reflection elements
- Snell's law and the refractive index of acrylic with the semicircular block
- Critical angle and total internal reflection
- Focusing and spreading of parallel rays by the biconvex and biconcave blocks
- Multiple-ray demonstrations with the two-, three- and four-slit settings
Scope of supply
The set comprises the graduated disc and base, the rotatable lamp house with 12 V, 24 W bulb, the slit disc, the lens carrier with lens, five acrylic refraction blocks and the 50 mm reflection elements. A 12 V supply, spares and quantities are confirmed on the quotation.

Frequently asked questions
How are angles read on the rotatable disc set?
Directly from the 230 mm disc, which is graduated from 0 to 360° at every 1° and has a centre mark.
Which acrylic blocks come with the set?
Semicircular, biconvex, biconcave, right angle prism and trapezoidal blocks, plus 50 mm wide reflection elements.
How many rays can the lamp house produce?
The rotatable slit disc gives single, double, triple or quadruple rays, and the adjustable lens makes them divergent, parallel or convergent.
What lamp is fitted?
The lamp house has a 12 V, 24 W bulb and can be rotated and held in any desired position.
What should a quotation request include?
Send the SKU JA-LOE-7978, the number of sets, whether 12 V supplies are needed and the delivery destination.
