Ray Diagram Light Microscope. A simple microscope consists of a convex lens of short focal length. Figure 3 shows the ray diagram which subsequently forms the image of an object or we can say a source of light.
Figures 45 47 illustrate the affect of a simple converging lens on each ray pattern. A popular method of representing a train of propagating light waves involves the application of geometrical optics to determine the size and location of images formed by a lens or multi lens system. To draw a ray diagram.
The image of the lamp collector lens bounded by the illuminated field diaphragm provides a flawless field of uniform illumination.
The interactive diagram provides a focus for the attention of the whole class. First the pupils explore the formation of images using a pinhole camera with one three and many pinholes. The numerical aperture of the optical fiber can be determined by using the angle αmax. In a dark field microscope the object is brilliantly illuminated against a dark background figure 410.
