Product Family Description

  • Desviación de haz de 60° con respecto a la hipotenusa si no está tratado
  • Su version no tratada funciona como prisma de dispersión de luz
  • Imagen orientada a la derecha

Los prismas de dispersión TECHSPEC® de Littrow de 60° pueden ser utilizados en una gran variedad de aplicaciones. Los prismas no tratados son usados para dispersar luz en sus componentes del espectro. Los prismas tratados se utilizan para desviar el haz 60° con respecto a la hipotenusa.

Dispersion Prisms (Uncoated)

Collimated white light enters into the A-C surface of the prism, is reflected at the hypotenuse surface, and then dispersed into its component spectrum at the B-C surface. Although Littrow prisms produce narrower dispersion than equilateral prisms, Littrow prisms are typically less expensive.

Beam Deviation Prisms (Coated)

Incident light enters into the aluminum coated B-C surface of the prism at the nominal angle and returns back using the same path. In spectrum dispersion applications utilizing white light, the resolution performance of Littrow prisms is equal to equilateral prisms since the optical path length through the glass substrate is the same distance round-trip. Additionally, light entered into the A-C surface will reflect twice inside the glass substrate before being emitted through the hypotenuse surface at 60°.
