Fleige Optik is one of the leading manufacturers of prisms (one-off, special and series production). Prisms are flat and solid glass elements or optical components, which are shaped by grinding and polishing in highest precision and have an optical effect. The angle, orientation and number of surfaces determine the type and function. Prisms are used to realize optical systems in a smaller space, to rotate or mirror images, and to combine or separate light rays using partially reflecting surfaces.
