    en.wikipedia.org/wiki/Back-illuminated_sensor

    A traditional, front-illuminated digital camera is constructed in a fashion similar to the human eye, with a lens at the front and photodetectors at the back. This traditional orientation of the sensor places the active matrix of the digital camera image sensor—a matrix of individual picture elements—on its front surface and simplifies manufacturing.

    A beam bender is essentially a large adjustable mirror, mounted into the color slot on the front of a lighting fixture. It is designed to allow a fixture to be mounted at right angles to the desired direction to be lit and have the output reflected (bent) accordingly. Drop in Boomerang

    The Selecon Pacific, an L-shaped ERS, has an irregular shape due to an integrated dichroic cold mirror, which effectively splits the visible wavelengths of the light beam from the infrared, allowing the heat to be drawn off by a heat sink and away from the instrument. This keeps the beam of the fixture cool allowing for the use of plastic gobos.

    The resulting beam of light is wide and soft-edged, creating soft shadows, and is commonly used for back light, top light, and side light. Another method of controlling the spread of light is to use either a top hat (also referred to as a snoot), which generally limits the light coming out, or a barn door , whose flaps work as though they were ...

    Hot mirror in front of the image sensor of a DSLR. Note reddish reflection of ambient light, and teal edge of filter. A hot mirror is a specialized dielectric mirror, a dichroic filter, often employed to protect optical systems by reflecting infrared light back into a light source, while allowing visible light to pass.

  7. Backlighting (lighting design) - Wikipedia

    en.wikipedia.org/wiki/Backlighting_(lighting_design)

    In photography, a back light (often the sun) that is about sixteen times more intense than the key light produces a silhouette. A fill flash used with a backlit subject yields more even lighting. The vertical angle of the back light can change the effect. A low angle can make the light hit the camera lens, causing lens flare. A high angle can ...

    en.wikipedia.org/wiki/Light_fixture

    A light fixture (US English), light fitting (UK English), or luminaire is an electrical lighting device containing one or more light sources, such as lamps, and all the accessory components required for its operation to provide illumination to the environment. [1] All light fixtures have a fixture body and one or more lamps.

    In a device with backside illumination, the silicon light sensor for each pixel is on the "back" side of the silicon wafer, opposite the transistors and metal wiring layers. This increases the efficiency of the sensor as compared to the traditional ("frontside illumination") technology, in which some of the light is scattered by the circuit ...
