30° - 60° - 90° Littrow Dispersion Prisms

Dispersion Prisms are used in applications that require separating the incident light into its component wavelengths. For example, when white light enters a Dispersion Prism, it is separated into its three components: red, green, and blue. Dispersion Prisms are ideal for spectroscopy or laser tuning.

1. What is dispersion prism?  


A dispersive prism is an optical prism, usually having the shape of a geometrical triangular prism, used as a spectroscopic component.

2. What’s the main application of dispersion prism?


Dispersion Prisms used in applications such as spectroscopy or laser tuning.


3. Are the dispersion prism can used in IR application?

Yes, the dispersion prisms are also available in multiple substrates that are ideal for Infrared (IR) applications.
