532nm Rectangular Flat-Top Beam Shaping Diffractive Optical Element (DOE)
532nm Rectangular Flat-Top Beam Shaping Diffractive Optical Element (DOE)
Los ntawm kev siv cov qauv me me, theem kis ntawm lub teeb uas hla dhau lub teeb pom kev zoo diffractive (DOE) raug hloov pauv, yog li ua rau muaj kev hloov pauv theem ntawm lub teeb tshwm sim. Qhov no ua rau lub teeb raug faib mus rau hauv ntau yam kev txiav txim diffraction. Siv cov yam ntxwv no, los ntawm kev teeb tsa cov kev txiav txim diffraction thiab qhov deb ntawm cov khoom, kev cuam tshuam tshwm sim ntawm ib lub dav hlau muab (feem ntau ntawm infinity lossis lub dav hlau focal ntawm lub lens), ua rau muaj kev faib tawm lub teeb tshwj xeeb.
Lub Diffractive Optical Element (DOE) no muaj kev ua haujlwm siab heev, thiab nws yog tsim tshwj xeeb rau kev siv 532nm laser ntsuab. Nws hloov cov kab teeb laser Gaussian txheem mus rau hauv qhov chaw tiaj tiaj, 380 µm × 150 µm nrog cov qauv ntug thiab kev faib hluav taws xob sib npaug.
Tsim los nrog 16-theem theem profile, lub beam shaper no ua tiav qhov zoo tshaj plaws diffraction efficiency (> 90%) thiab lub zog sib xws (> 90% RMS), tshem tawm cov chaw kub thiab txo cov kev puas tsuaj thermal thaum lub sijhawm ua laser precision.
Lub DOE muaj qhov loj Φ25.4 hli (1 nti) nrog lub qhov qhib Φ15 hli, ua kom muaj kev sib txuas zoo rau feem ntau ntawm cov khoom siv kho qhov muag thiab cov log lim.
COV KHOOM PAWG
Wavelength tau tsom mus rau kev muab cov khoom siv kho qhov muag siab rau 20 xyoo
