Binary optical element
WebTwo sections (16,18) of a binary optical element are perpendicularly or vertically offset relative to each other to induce a shift in phase from light beams (18,26) transmitted through the sections. An offset (d offset ) of λ/2(n-1 ) will cause a Π shift in the phase between beams transmitted through the two sections of the binary optical element. WebApr 14, 2024 · Membrane diffractive optical elements formed by fabricating microstructures on the substrates have two important characteristics, ultra-light mass (surface mass density < 0.1 kg/m2) and loose surface shape tolerances (surface accuracy requirements are on the order of magnitude of centimeter).
