difference between ordinary prism and constant deviation prism
By keeping the prism in minimum deviation position, the RI of the prism can be calculated efficiently.

The minimum deviation of a prism can be calculated using the formula: δ = (n - 1)A, where δ is the minimum deviation, n is the refractive index of the prism, and A is the angle of the prism. If the refractive index of the prism is three to the power of half, or √3, and the value of A is known, the minimum deviation can be calculated using the formula.

It is named after the type of prism used in the instrument. A constant deviation prism has the property that the angle between light entering the prism (the incident light) and light exiting the prism (the emergent light) is always the same, no matter what the angle of the incident light to the prism.
