A kit lens is a "starter" lens which can be sold with an interchangeable-lens camera such as a mirrorless camera or DSLR. It is generally an inexpensive lens priced at the lowest end of the manufacturer's range so as to not add much to a camera kit's price.
Light travels through a single lens and a mirror is used to reflect a portion of that light through the viewfinder – hence the name "single-lens reflex". While there are variations among point-and-shoot cameras , the typical design exposes the sensor constantly to the light projected by the lens, allowing the camera's screen to be used as an ...
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. In the on state, light from the projector bulb is reflected into the lens making the pixel appear bright on the screen.
Optically coated mirrors and lenses. An optical coating is one or more thin layers of material deposited on an optical component such as a lens, prism or mirror, which alters the way in which the optic reflects and transmits light. These coatings have become a key technology in the field of optics.
Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
The first digital rangefinder camera commercially marketed was the Epson R-D1 (released in 2004), followed by the Leica M8 in 2006. [16] They were some of the first digital lens-interchangeable cameras without a reflex mirror, but they are not considered mirrorless cameras because they did not use an electronic viewfinder for live preview, but, rather, an optical viewfinder.

Catadioptric lens - catadioptric lenses are a form of telephoto lens but with a light path that doubles back on itself and with an objective that is a mirror combined with some form of aberration correcting lens (a catadioptric system) rather than just a lens. A centrally-placed secondary mirror and usually an additional small lens group bring ...
