Diffractive Optical Elements (DOE)
What is a diffractive optical element
Diffractive Optical Elements (DOE) are phase elements, which are based onThe theory of optical wave diffraction utilizes a continuous relief-type or step-type structure etched on the substrate to obtain extremely high diffraction efficiency.Its small size, light weight, design freedom, imagingGood quality, broad application prospects in the fields of optical imaging, optical data storage, laser technology, biomedicine, etc.
There are three types of functions:Beam shaper, ,Beam splitterandDiffusers(also known as homogenizer)
DOE Application Areas
Laser material processing
Shaping and beam splitting of laser beams in welding, cutting, scribing, soft welding and drilling processes
Photolithography and holographic illumination
Homogenization of projection beams in mask projection systems, structured pupil illumination, uniform field illumination of vertical and highly inclined planes
Diffractive optics for medical laser therapy and diagnostic instruments
Distance and position sensors, motion detection
Optical distance and speed measurement using laser beams
Beam splitters, wavelength selection and silicon optics applications
Electron beam lithography (EBL)UV lithographyProximity/contact lithography, stepper lithography, etc.
Two-photon 3D printing (Two-photonpolymerization)
Focused Ion Beam EtchingDeep reactive ion etching, inductively coupled plasma etching, ion beam sputtering etching, etc.
Nano-thermal embossing, UV-curable embossing, micro-contact printing (soft etching)
Magnetron sputteringAtomic layer deposition.Ion beam sputtering, ,Plasma chemical vapor deposition, etc.
