Mirror Assemblies

Mirror assemblies are composed of a single or several mirrors mounted for a particular function. Mirror assemblies consist of a light weight hyperbolic mirror to minimize its inertia, mirror support system and the central area of the mirror consists of interface to mount onto mechanical equipment that provides optical alignment. There are many types of mirror assemblies. Examples include a rear view mirror assembly, high resolution mirror assembly, scan mirror assembly (SMA), x-ray mirror assembly (XMA), secondary mirror assembly, imaging flat mirror assembly and dichroic mirror assembly. A rear view mirror assembly consists of a frame and a mirror that is supported by the frame. A high resolution mirror assembly (HRMA) is comprised of nested mirrors, forward and center aperture plates, inner and outer cylinders, and post collimators. A scan mirror assembly (SMA) provides the development of crosstrack scanning motion and allows the mirror to be scanned through an instrument’s field. An x-ray mirror assembly (XMA) consists of four nested Wolter-I mirrors with the focal length of 2.40 meters. A secondary mirror assembly has a very expensive optical mirror that has very delicate reflective surface. An imaging flat mirror assembly is formed by a combination of two flat mirrors that are mounted at 45°. A dichroic mirror assembly helps to form a diachronic mirror mount which is available in two versions, one of them is at normal incidence and the other is at 45°. Other mirror assemblies are commonly available.

There are several ways in which mirror assemblies function. A rear view mirror assembly provides safety because it can be used to restore proper rear vision both at the driver and passenger side. Some examples of high resolution mirror assembly specifications include mirror diameters of 1.23, 0.99, 0.87 meters, coating thickness is 330 Å, focal length of 10.066 m, and mirror length of 84 cm. A scan mirror assembly (SMA) derives the timing from a 10 MHz clock which is routed by buffers in the multiplexer. An x-ray mirror assembly (XMA) consists of eight mirror shells that are made of glass ceramic which are coated with thin layer of gold to increase the reflectivity of the x-ray. Some specifications of the secondary mirror assembly includes a coating of aluminum, optical diameter of 1116 mm, and the high spatial frequency surface errors has a value of CIR > 0.98. A dichroic mirror assembly mount is provided with a 40 pitch micrometer adjusting screw. Mirror assemblies are designed and manufactured to meet most industry specifications.

Mirror assemblies are used in many applications. Examples include interior panel bonding, foam lamination, and a rear view mirror in vehicles. Mirror assemblies follow National Institute of Standards and Technology (NIST) safety standards.
