What Is Schusters Method?
Schuster's is the best method of focusing the telescope and the collimator for parallel/paraxial rays within the space available in the dark room. Next bring the telescope between the prism and the eye and move it slightly this way or that so that you can see the image of the slit in it.

.

In this regard, why does Schuster's method work?

Schuster's Method. Obtaining the slit image in the field of view the table carrying the prism is slowly rotated. It is observed that the image moving in one direction suddenly reverses its direction of motion. It makes the prism to rotate so that the angle of incidence is increased by a little.

Likewise, how do you level a prism table? Place prism table, note that the surface of the table is just below the level of telescope and collimator. Place spirit level on prism table. Adjust the base leveling screw till the bubble come at the centre of spirit level. Clamp the prism holder.

One may also ask, why the spectrometer is set for parallel rays?

A collimator is positioned to convert diverging rays to parallel rays, simply because that is its intended purpose, and is the definition of the word collimate in the context of optics. The better the optical alignment, the sharper the image.

Why are telescope and collimator adjusted for parallel rays of light?

The purpose of a telescope is to form an image of a distant object. Even so, most telescopes have a focus control for fine adjustment. A collimator is positioned to convert diverging rays to parallel rays, simply because that is its intended purpose, and is the definition of the word collimate in the context of optics.

What is angle of minimum deviation?

minimum angle of deviation. The smallest angle through which light is bent by an optical element or system. In a prism, the angle of deviation is a minimum if the incident and exiting rays form equal angles with the prism faces. The angle is important relative to prism spectroscopes because it can be easily determined.

Why collimator is used in spectrometer?

COLLIMATOR is used to collimate the beam of light coming. It consists of biconvex lens which converges the light in a direction and to get a parallel beam of light.
