What is a prism?

In optics, a prism is a transparent optical element with flat, polished surfaces that refract light.

Which of the following is a high power variant of a prism?

Glan–Taylor prism, a high-power variant of which is also denoted as Glan–laserprism Glan–Thompson prism One polarization is deviated by different refraction only: Rochon prism Sénarmont prism Both polarizations are deviated by refraction: Wollaston prism Nomarski prism– a variant of the Wollaston prism with advantages in microscopy

What is a reflective prism?

Reflective prisms are used to reflect light, in order to flip, invert, rotate, deviate or displace the light beam. They are typically used to erect the image in binoculars or single-lens reflex cameras – without the prisms the image would be upside down for the user. Many reflective prisms use total internal reflection to achieve high reflectivity.

What is a dispersive prism used for?

A dispersive prism can be used to break white light up into its constituent spectral colors (the colors of the rainbow). Furthermore, prisms can be used to reflect light, or to split light into components with different polarizations.
