Optical Glasses
Product Code : JA-SL-5809
The Optical Glasses listing (SKU JA-SL-5809) is a group of Perspex optical blocks, each 19 mm thick, for studying refraction with a ray box. It covers a rectangular block of 114 x 73 mm, an equilateral triangular prism with 76 mm sides, a 30-60-90 degree triangular block, a circular block of 98 mm diameter, two biconvex shapes of 140 x 178 mm and 140 x 98 mm, and a biconcave shape of 140 x 98 mm.

Experiments with the blocks
Used with a ray box on a sheet of paper, the blocks cover the refraction topics of school physics:
- Refraction through a rectangular block and measuring the lateral shift
- Dispersion and deviation through the 60 degree triangular prism
- Total internal reflection in the 30-60-90 triangle and the circular block
- Converging and diverging beams through the biconvex and biconcave shapes
Scope of supply and ordering
The blocks can be ordered as the full group or by shape. Quantities and packing are confirmed on the quotation.
