Double blazed binary diffraction optical element beam splitter |
摘要 |
A double blazed binary diffractive optical element beam splitter having alternating and opposing individual blazed diffraction gratings upon a multilevel surface relief phase grating structure for splitting an incident monochromatic light beam into a first and second diffracted light beams. The double blazed binary diffractive optical element and two single blazed binary diffractive optical elements can form either a beam splitting apparatus or a beam combining apparatus. Double blazed binary diffractive optical elements and sets of two single blazed binary diffractive optical elements can form beam splitting and combining apparatuses to produce a single beam or two closely spaced beams.
