CNC-Polished los yog MRF-Polished Aspheric Lenses

Aspheric lo ntsiab muag, lossis aspheres yog tsim los kom muaj qhov ntev focal ntev dua li qhov ua tau nrog cov lo ntsiab muag kheej kheej. Ib qho aspheric Lens, los yog asphere nta ib qho chaw uas nws lub vojvoog hloov nrog qhov kev ncua deb ntawm qhov chaw kho qhov muag, qhov tshwj xeeb no tso cai rau cov lo ntsiab muag aspheric kom tshem tawm cov kev tsis sib haum xeeb thiab txo qis lwm yam aberrations txhawm rau xa cov kev ua tau zoo kho qhov muag. Aspheres yog qhov zoo tagnrho rau cov ntawv siv laser tsom raws li lawv tau ua kom zoo rau qhov chaw me me. Tsis tas li ntawd, ib lub lens aspheric feem ntau tuaj yeem hloov ntau lub ntsiab lus nyob rau hauv cov duab kos duab.

Txij li thaum aspheric lo ntsiab muag raug kho rau spherical thiab coma aberrations, lawv yog qhov tsim nyog rau cov f-number tsawg thiab cov ntawv thov siab, condenser zoo aspheres feem ntau yog siv hauv cov tshuab hluav taws xob ua haujlwm siab.

Paralight Optics muaj CNC precision-polished loj-inch aspherical lo ntsiab muag, nrog thiab tsis muaj kev cuam tshuam kev cuam tshuam (AR) txheej. Cov lo ntsiab muag no muaj nyob rau hauv qhov ntau thiab tsawg, muab qhov zoo ntawm qhov chaw zoo, thiab tswj cov M squared qhov tseem ceeb ntawm cov kab lus nkag tau zoo dua li lawv cov pwm aspheric lens counterparts. Txij li qhov saum npoo ntawm lub lens aspheric yog tsim los tshem tawm cov kev tsis sib haum xeeb, lawv feem ntau siv los sib tsoo lub teeb tawm ntawm fiber ntau lossis laser diode. Peb kuj muab cov cylindrical lo ntsiab muag, uas muab qhov zoo ntawm aspheres nyob rau hauv ib-dimensional tsom daim ntaub ntawv.

Tsim

♦ Qhov Zoo Radius Qhia tias qhov chaw ntawm Curvature yog nyob rau sab xis ntawm lub Lens
♦ Tsis zoo Radius Qhia tias qhov chaw ntawm Curvature yog rau sab laug ntawm lub Lens
Aspheric Lens Equation:
Molded-Aspheric-Lens
Qhov twg:
Z = Sag(Nto Profile)
Y = Radial Distance los ntawm Optical Axis
R = Radius ntawm Curvature
K = Conic Constant
A4 = 4th Order Aspheric Coefficient
A6 = 6th Order Aspheric Coefficient
Ib = nth Order Aspheric Coefficient
