A K-mirror is a system of 3 plane mirrors mounted on a common motor axis which runs parallel to the chief ray of the system. If looking at the system parallel to the mirror surfaces, where only the edges of the mirrors remain visible, the middle mirror and the front and back mirror look like the backbone and legs of a capital-K; this illustrates the origin of the name.
The mirrors are arranged in a matrix and have two states, "on" or "off" (digital). In the on state, light from the projector bulb is reflected into the lens making the pixel appear bright on the screen. In the off state, the light is directed elsewhere (usually onto a heatsink), making the pixel appear dark. Colours could be produced by various ...
A DMD chip has on its surface several hundred thousand microscopic mirrors arranged in a rectangular array which correspond to the pixels in the image to be displayed. The mirrors and supporting mechanical structures are constructed using surface micromachining. [4] The mirrors can be individually rotated ±10-12°, to an on or off state.

A three-mirror anastigmat is an anastigmat telescope built with three curved mirrors, enabling it to minimize all three main optical aberrations – spherical aberration, coma, and astigmatism. This is primarily used to enable wide fields of view, much larger than possible with telescopes with just one or two curved surfaces.
A Kirkpatrick–Baez mirror, or simply KB mirror, focuses beams of X-rays by reflecting them at grazing incidence off a curved surface, usually coated with a layer of a heavy metal. It is named after Paul Kirkpatrick and Albert Baez , the inventors of the X-ray microscope .
A mirror with a larger effective critical angle can be made by exploiting diffraction (with non-zero losses) that occurs from stacked multilayers. [3] The critical angle of total reflection, in degrees, becomes approximately 0.1 ⋅ λ ⋅ m {\displaystyle 0.1\cdot \lambda \cdot m} , where m {\displaystyle m} is the "m-value" relative to ...
