Impressive results with these in.jumbo in. unbreakable blocks!
For rapid demonstration and investigation on the bench surface using “jumbo”-sized elements of unbreakable, scratch-resistant, polished Lucite.™ Results are bold and positive. The path of ray streaks is enhanced by the white backing and, because of the homogeneous material, the path through the block is true. Demonstrations set up in seconds and can be performed with ease and confidence. Perfect for refraction experiments, these clear polished blocks are 19mm thick, and free from scratches and bubbles. The edges are slightly beveled; white back shows clearly the path of the light rays through the block.
