Rectangular Refraction Acrylic Block, 125 x 65 x 18mm

This rectangular acrylic block measures 5" (125 mm) long, 1.5" (65 mm) wide, and 0.7" (18 mm) thick. The block is made from bubble-free acrylic with slightly beveled edges, producing clean, undistorted light paths ideal for refraction and reflection experiments in optics coursework. The transparent material clearly demonstrates how light bends at each interface when entering and exiting the block, making it an effective teaching tool for Snell's law and critical angle investigations. The block can also be used for photography lighting and distortion effects.
