WebIn photography, angle of view(AOV)[3]describes the angularextent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view. It is important to distinguish the angle of view from the angle of coverage, which describes the angle range that a lens can image. WebFor 8-14 μm Wavelengths. Ophir Long Wave IR (LWIR) lenses provide a crisp image over the full zoom range, with MTF close to the diffraction limit.

WebIn a camera lens, the focal point is located on the sensor if the image is “in focus”. The Field of View (FOV) of a camera and lens is a measure of the spatial dimensions that the camera and lens can include in an acquired image. It is correctly specified in terms of the angle between the two edges of the camera image.

WebSince angular FOV is independent of object distance, it is the more frequently used form of FOV. For an imaging sensor (or film) of size a in a given direction, the angular FOV in that direction is 2 arctan (a / 2 s i). When the system is set to focus at optical infinity, this takes on the familiar form of 2 arctan (a / 2 f). The shape of the ...
