>> Optical Parallel
- A parallel optical interface is a form of fiber optic technology aimed primarily at communications and networking over relatively short distances (less than 300 meters), and at high bandwidths.



>> Other information
>> What displayed?
* When the polished surface of the optical plane is placed in contact with the test surface, light and dark bands are formed when viewed with monochromatic light. These bands are called interference fringes and their shape gives a visual representation of the flatness of the surface under test. Surface flatness is represented by the number of curves and the distance between the fringes. Straight, parallel and evenly spaced interfering edges indicate the work surface flatness is equal to or higher than the reference surface.

>> Applications
* Surface flatness measurements of polished surfaces can be determined visually by comparing variations between a work surface and that of an optical plane. Optical flats are versatile optical components used in a wide variety of applications, such as: inspecting measuring units for wear and accuracy, as well as inspecting various components including windows and prisms. glasses, filters, mirrors, etc. Optical windows for interferometer requirements.

>> How?
* An optical plane uses a noise property to represent the flatness of the desired surface. When an optical plane, also called a test plate and the working surface is placed in contact, an air wedge is formed. Areas between the plane and the non-contact work surface form this air wedge. The change in the thickness of the air wedge will determine the shape and direction of the interference bands. The amount of curvature represented by the noise bands can be used to determine the flatness of the surface. If the air wedge is too large, then more evenly spaced lines can appear, making it difficult to analyze the formation pattern. Simply applying pressure to the top of the optical plane alleviates the problem.
* Determination of the flatness of any particular region of a surface is accomplished by creating two parallel imaginary lines; one is between the ends of any edge, and the other is at the end of any edge. The number of edges lying between the lines can be used to determine the flatness. Monochromatic light is used to create sharp contrast for viewing and for determining flatness as a function of single wavelength.
