Glass blocks are commonly used in the physics classroom to demonstrate reflection and refraction. These blocks can also be used to demonstrate how light travels through an objects and also how light acts on the surface of an object. An essential for your lab. Made from optical glass with optically worked surfaces. All angles accurately worked with edges slightly bevelled and glass free from bubbles. Size 100 x 60 x 18 mm. Refractive index is 1.5.
