若宾——伊冯公司在应用全息光栅之后,又制造了能校正象差的光栅(Ⅳ型)和两种新型的闪耀的全息衍射光栅。用全息制造的这种闪耀光栅,是用锯齿面代替了经典的正弦面。一方面,这种新型的光栅衍射效率很高,同时它具有用全息法制造光栅的优越性,如:微弱杂散光,无鬼线,能制造大量的线条,波面质量很好,能校正象差。另一方面,若宾——伊冯公司的这种衍射光栅是用离子法制造的。这利新型光栅的条纹直
After applying the holographic grating, the Rabin-Ivan Company manufactured another grating (Type IV) capable of correcting aberrations and two new types of blazed holographic diffraction gratings. This blazed grating made with holograms replaces the classic sine plane with serrated surfaces. On the one hand, this new type of grating has a high diffraction efficiency and at the same time it has the advantages of using holograms to produce gratings such as faint stray light, no ghost lines, a large number of lines, good wavefront quality and correct aberrations . On the other hand, such a diffraction grating of the Rabin-Ivan company is manufactured by the ion method. This new straight raster stripe straight
