	Focal plane shutter - Wikipedia, the free encyclopedia
		The main advantages of the focal plane shutter is that the interchangeable lenses do not each need to have a central shutter built into them, and quite fast effective shutter speeds are possible.
		The traditional type of focal plane shutter in 35mm cameras, pioneered by the Leica camera company, uses two shutter curtains that run horizontally across the film plane.
		One limitation of the focal plane shutter is that the flash synchronisation speeds are generally quite slow.

		In (Equipment for taking photographs (usually consisting of a lightproof box with a lens at one end and light-sensitive film at the other)) camera design, a focal plane shutter is so-called because it is right in front of the focal (film) plane of the camera.

	Slit-Scan Photography with Large Format Cameras
		In fact, a focal plane shutter is just such a device and the distortion produced by these shutters is fairly well understood by photographers at large and the distortions thus produced are called focal-plane shutter distortion.
		A very famous photograph that depends on focal plane shutter distortion for its visual impact is one made by Henri Lartigue with a large camera equipped with a focal plane shutter.
		Another photographer who took advantage of the characteristics of focal plane shutter distortion but in a more controlled way was Robert Doisneau who photographed a couple spinning on a turntable as a slowed down focal plane shutter exposed the scene sequentially from one edge of the film to the other.

	Olympus Microscopy Resource Center: Physics of Light and Color - Simple Bi-Convex Thin Lenses: Interactive Java Tutorial
		The focal length of a lens is defined as the distance between the principal plane and the focal plane, and every lens has a set of these planes on each side (front and rear).
		The object (or specimen) being imaged by the lens is positioned in the object plane to the left of the lens and is represented by a red arrow that travels upward from the optical axis, which passes through the center of the lens, perpendicular to the principal planes.
		The distance between the front principal plane of the lens and the specimen is known as the object distance, and is represented by the variable a in Figure 1.

		However, one drawback to committing to one focal plane is that events taking place in other optical sections are no longer seen.

		The consequence of your secondary mirror size selection in a Newtonian reflector is that it affects the size of the fully illuminated region at the focal plane.
		(A given spot on the focal plane is said to be "fully illuminated" if it receives 100% of the light gathered by the primary mirror.) Outside of the fully illuminated region, the illumination level gradually drops off.
		This 1.5" x 1.5" portion of the focal plane is almost the size of a 35 mm frame of film (corner to corner).

	Nikon MicroscopyU: Perfect Two-Lens System Characteristics - Interactive Java Tutorial
		During investigations of a point source of light that does not lie in the focal plane of a lens, it is often convenient to represent a perfect lens as a system composed of two individual lens elements.

		In the case where a point set of S(1) lies in a plane perpendicular to the optical axis of the lens, then the corresponding conjugate points in set S(2) would also lie in a plane that is perpendicular to the axis.

		This document determines the field depth of the focal plane for the purpose of tolerancing detector surface deviations.
		Errors in detector flatness, squareness to the optical axis, and placement along the optical axis must therefore be controlled so that the whole of the surface lies within the field depth of the focal plane.
		The focal scale is 0.02"/pixel, and so the allowable blur circle diameter is ~ 0.6 pixel.
