Front Silvered Glass Mirrors
Front silvered mirrors avoid the double reflections which you get with normal rear-silvered mirrors where light is reflected off the front surface of the glass as well as the silvered surface. Warning: Handle with care as they are susceptible to scratching although the silvering is protected by a vacuum deposited quartz coating.
We stock top quality Acrylic and Glass Lenses for all your optical experiments in a range of sizes and focal lengths. The Acrylic lenses are the same as the lenses used in the telescope kits. The Glass lenses are available either with a standard 50mm diameter for optical benches or similar or as a range with a variety of diameters, most of which are 2 lens Achromats for less colour aberration.
