As light rays pass through the lens, the parallel light rays bend and converge on the object in focus creating a larger image of the object on the human retina. There are different types of lenses, including simple lenses and compound lenses....

Microscope - Image Formation, Optics, Magnification: The objective collects a fan of rays from each object point and images the ray bundle at the front focal plane of the eyepiece. The conventional rules of ray tracing apply to the image formation. In th
1 cm of real object is projected by lens to 1 cm of sensor (real size of sensor), that is 1:1 = 1x magnification Crop is not necessary to be mentioned but sizes of sensors are different so the size of 1cm object can be over whole image (1cm sensor) or only tiny thing in case...
. Images are classed as real or virtual. A real image occurs when the rays of light from the object actually converge to form an image and can be seen on a screen placed at the point of convergence. For example, the image produced by the refraction of light rays by a convex lens (...
The image is therefore magnified by a factor of two. However, the net effect of this is to greatly increase unsharpness (see Ch. 3.6) so that, in order to be able to view the same small detail in the magnified view, the smaller focal spot must be used. This has the effect of ...
