WebReal images occur when objects are placed outside the focal length of a converging lens (s>f). If the lens is converging but the distance from the object to the lens is smaller than the focal length, the image will be virtual. Diverging lenses always produce virtual images. This calculator shows a ray diagram when the image is real. Magnification WebAs an example, let us calculate the size of a specimen that will be recorded on the 1/2" (6.4 × 4.8 mm) camera sensor if a microscope objective lens magnification is 40 and the camera relay lens magnification is 0.35: To determine magnification, you can use a special calibration slide with engraved 0.01 mm marks (1 division equals 0.01 mm). WebAngle of view (in degrees) = 2 ArcTan (sensor width / ( 2 x focal length))) * (180/π) Note: You only need the (180/π) part if your calculator is working in radians. If yours is working in degrees, leave that part out! Since this equation has the sensor size as one of the factors, it also covers crop factor. drive ugr
