具有40％衍射效率、计算机制作的全息光学元件,现已由霍尼威尔公司制成。这些元件是采用电子束直接写入的方式制作的。这些元件的效率据说是目前制作的其它这种全息图的四倍。限制全息透镜发展的因素,包括有限的衍射效率,高色散和缺少高分辨率的平版印刷工艺:以前,是先绘制出较大尺寸的掩模,而后再将掩模照相缩版制成。霍尼威尔工艺取消了 A 40% diffraction efficiency, computer-generated holographic optical element is now made by Honeywell. These components are fabricated using direct electron beam writing. The efficiency of these components is said to be four times that of other such holograms currently produced. Factors that limit the development of holographic lenses include limited diffraction efficiency, high chromatic dispersion, and lithographic processes that lack high resolution: Previously, larger-sized masks were first drawn and the masks were then photolithographed. Honeywell process was canceled
