Focal Length Calculator

Due to the focal length and the size of the imager (CCD or CMOS sensor), the visible range can be calculated. Image sensors consist of a matrix of light-sensitive components. The incident light transmits through the inner photoelectric effect its energy to the electrons of the sensor. The size of image sensors is usually given in inches. The designation of the chip size has been derived from the outer diameters of the old image pickup tube, wherein the light-sensitive surface of the sensors is smaller than the outer diameter. So you have the length of the light-sensitive screen sizes to know the correct dimensions of the light-sensitive surface to calculate. The Focal Length Calculator allows you to calculate the necessary focal lengths or the visible image areas.
