A prism is a solid glass object given a specific geometric shape for the purpose of dispersing, deviating, rotating or displacing a beam of light. A micro prism, as the name suggests, is a very small version of an optical prism. Though there are many types of prisms, micro prisms are generally used to direct light in fiber optic communications, particularly in optical switches. Two types of micro prisms prove useful for these and other applications.
What Makes Micro Prisms Important?
Micro prisms provide an efficient way to change a beam of light’s directory inside an assembly or fiber optic device. When light goes through one of the faces on the prism, it’s refracted. Depending on the design of the prism, the light may be propelled in various angles before exiting the prism. The main purpose of a micro prism in fiber optics is to direct beams of light from one optical channel to another with high precision. Though micro prisms are small, they bring several big advantages to optics projects that employ them, including:
All these benefits make a micro prism ideal for use as a circulator, interleaver or MEMS for fiber optic applications.

How Micro Prisms Are Produced
A micro prism’s performance is closely related to its design and manufacturing. In general, micro prisms are cut and ground out of optical glass, polished to meet precise specifications, given an outer coating and checked for defects. We make two types at Shanghai Optics coated or uncoated according to customer’s needs.
Though these prisms feature different shapes, they share many of the same physical properties, including reflectivity, surface quality and working wavelength. S.O. can make custom micro prisms using a number of different materials and coatings, including coatings for different UV, visible and IR wavelengths upon request.

Right-angle and penta micro prisms have a number of applications in fiber optics and beyond. Many of these applications require prisms that are tailored to unique specifications and fine-tuned for perfect performance. At Shanghai Optics, we manufacture micro prisms that meet both of these requirements. To ensure that our custom optical switch prisms meet your specifications, our production staff members follow ISO 9001 standards and use state-of-the-art metrology equipment to test performance.
