Semi Circular Acrylic Block
Product Code : JA-PLE-4155
The Semi Circular Acrylic Block (SKU JA-PLE-4155) is a clear, fully polished acrylic half-disc used with a ray box or optical pins to study refraction, the critical angle and total internal reflection. This semi-circular acrylic block for critical angle experiments is listed at 90 mm diameter in 16 mm and 25 mm thicknesses, and JaincoLab supplies it for school and college optics practicals.
Specifications
The block is a semicircle of clear acrylic 90 mm in diameter, with all faces fully polished, and it is offered in two thicknesses, 16 mm and 25 mm, to suit ray boxes and pin methods.

Applications of the semi-circular acrylic block for critical angle experiments
A ray aimed at the centre of the flat face passes through the curved face without bending, so refraction at the flat face can be studied on its own; increasing the angle inside the block reveals the critical angle and then total internal reflection.
- Measuring the critical angle of acrylic
- Demonstrating total internal reflection
- Verifying the laws of refraction at a plane surface
- Finding refractive index from the measured critical angle

Frequently asked questions
What sizes are available?
The block is 90 mm in diameter and is listed in 16 mm and 25 mm thicknesses.
Why use a semi-circular block?
A ray directed at the centre of the flat face crosses the curved face undeviated, which makes the critical angle and total internal reflection easy to observe.
Are the faces polished?
Yes. All faces of the clear acrylic block are fully polished.
