简单介绍
棱栅（光栅+棱镜）是一种光学棱镜，在该棱镜的某一（极少出现两个）扁平（极少出现曲面）功能表面上加工有一块透射光栅。棱柵有直接的视角或者说没有波长偏移。这一特性使其能够将相机转变成摄谱仪，方法是在光路中插入棱栅。

A Grism is a Prism That Has a Transmission Grating on One Of its Plane Surfaces.
A Grism (GRating+prISM) is an
optical prism which has a transmission grating fabricated onto one
(rarely two) of its plane (rarely curved) functional surfaces. Grisms
have a straight view or undeviated wavelength. This property allows them
to transform a camera into a spectrograph by inserting the grism in the
optical beam path. This can be used in various applications, e.g.
astronomy. By selecting the groove density and the apex angle of the
prism accordingly, the straight view wavelength and the angular
dispersion of the grism can be adapted to the needs of the specific
application
