簡單介紹

棱柵（光柵+棱鏡）是一種光學(xué)棱鏡，在該棱鏡的某一（極少出現(xiàn)兩個）扁平（極少出現(xiàn)曲面）功能表面上加工有一塊透射光柵。棱柵有直接的視角或者說沒有波長偏移。這一特性使其能夠?qū)⑾鄼C轉(zhuǎn)變成攝譜儀，方法是在光路中插入棱柵。

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
