How to Reduce Spherical Aberration The following 5 methods are usually used to reduce the spherical aberration. By Stop Method. By using plano-convex lenses. By using two convergent lenses separated …

Aberration in Optics In the simple theory of image formation by lenses, it is assumed that an object is situated very close to the principal axis and each point object …

Suppose we have two lenses of focal lengths f1 and f2 separated by a distance x as shown in fig below. L1, L2 correspond to the position of two lenses …

The matrix Tm is called Translation Matrix. The matrices can be used to find the position of the final image. The method of writing linear equations for the coordinates of …

What is fermat’s principle? This principle states that the light always travels that path in a medium from one point to another point which takes the minimum (i.e least) time. …

The branch of physics which deals with the study of optical phenomenon like reflection, refraction, dispersion, interference, diffraction, polarization etc. is known as optics. Optics is classified into two categories: …

Huygens principle of Wave Theory Huygens Principle helps us to find the position of a given wavefront at any instant if we know its present position. A wavefront is defined …
