Custom Optical Wedge Prism Fabrication

Sydor Optics manufactures custom optical wedges and thin prisms used in a variety of applications. Flat optics with a wedge angle are typically used in laser applications for beam steering and beam displacement or for preventing stray-back reflections, but can also be used in virtually any type of optical component to change the direction of light.

With decades of experience Sydor Optics is the preferred choice for exceptional cosmetics, wedge angle tolerance and surface roughness. Wedge prisms are manufactured to meet your exacting specifications in a wide variety of custom shapes, sizes, materials with optional coatings for ultraviolet (UV), visible (VIS) and infrared (IR) applications.
