    Equilateral Dispersing Prisms
    商品货号:ECS000787
    商品品牌:Thorlabs
    详细介绍

    Thorlabs' Dispersive Equilateral Prisms are made from F2 and SF11 glasses, which have high refractive indices and a low Abbe Number ,Vd. This ensures maximum dispersive power, making them suitable for use in wavelength separation applications. Compared to diffraction gratings, Thorlabs' Dispersive Equilateral Prisms have lower stray light and no higher order problems. These prisms are available in sizes ranging from 10mm to 50mm.

    The dispersive equilateral prisms are typically used at the minimum angle of deviation. This is the angle where the wavelength of interest travels parallel to the base of the prism and the angle of incidence is equal to the angle of refraction when measured with respect to the normal of the face of the prism at the respective interface. At the minimum angle of deviation, a maximum clear aperture is achieved and reflective loss in the P-polarization is reduced due to the close proximity to Brewster’s angle of the incident light. For S-polarization, an anti-reflective coating will enhance transmission.

    Please refer to the Selection Guide tab above for assistance in selecting the appropriate prism for your application.
