Dispersion Prisms | 色散稜鏡

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.

Edmund Optics offers the world’s largest inventory of off-the-shelf optical components, including Dispersion Prisms. Edmund Optics’ Dispersion Prisms are available uncoated, or with reflection or anti-reflection coatings. Dispersion Prisms are also available in multiple substrates that are ideal for Infrared (IR) applications. Infrared (IR) substrates include Calcium Fluoride (CaF₂), Germanium (Ge), or Zinc Selenide (ZnSe). Calcium Fluoride (CaF₂) is a low index material featuring excellent transmission from 0.19 - 7μm, ideal for use in the Ultraviolet (UV) through Infrared (IR). Germanium (Ge) is is a high index material, ideal for maximizing optical paths from 3 - 12μm. Zinc Selenide (ZnSe) is commonly used from 1 - 16μm, ideal for use with CO₂ lasers.
