Precision Flat Optical Windows nrog lossis tsis muaj AR Txheej

Cov qhov rais kho qhov muag muab kev tiv thaiv ntawm qhov kho qhov muag lossis cov khoom siv hluav taws xob nkag siab thiab ib puag ncig sab nraud.Nws yog ib qho tseem ceeb los xaiv lub qhov rais uas xa cov wavelengths siv nyob rau hauv lub system.Tsis tas li ntawd, cov khoom siv substrate yuav tsum muaj peev xwm tiv taus ib puag ncig ntawm daim ntawv thov.Windows muaj txiaj ntsig zoo rau kev tiv thaiv lub laser tso tawm los ntawm ib puag ncig cuam tshuam thiab rau kev siv cov kab sampling.Peb muab Windows nyob rau hauv ntau hom substrates, qhov ntau thiab tsawg thiab thicknesses kom tau raws li txhua daim ntawv thov xav tau.

Paralight Optics muaj ob qho tib si tus qauv thiab siab precision optical tiaj qhov rais fabricated los ntawm ntau yam substrate ntaub ntawv rau siv nyob rau hauv ib tug loj ntau yam ntawm laser thiab muaj daim ntaub ntawv.Peb cov substrates muaj xws li N-BK7, UV Fused Silica (UVFS), Sapphire, Calcium Fluoride, Magnesium Fluoride, Potassium Bromide, Infrasil, Zinc Selenide, Silicon, Germanium, los yog Barium Fluoride.Peb lub qhov rais laser muaj ib lub wavelength-specific AR txheej nyob rau hauv ib ncig ntawm feem ntau siv laser wavelengths thiab ib tug xaiv wedge, thaum peb precision qhov rais muaj los yog tsis muaj ib tug broadband AR txheej muab zoo kho qhov muag kev ua tau zoo rau lub kaum sab xis ntawm qhov xwm txheej (AOI) ntawm 0 ° thiab 30 °.

Ntawm no peb sau Calcium Fluoride Flat Window.Calcium fluoride muaj qhov nqus coefficient tsawg thiab muaj kev puas tsuaj loj, ua rau cov qhov rais no yog qhov kev xaiv zoo rau kev siv nrog qhov chaw dawb.Peb cov calcium fluoride (CaF₂) High-Precision Flat Windows yog uncoated los yog nrog broadband anti-reflective txheej.Lub qhov rais tsis muaj coated muab kev sib kis tau zoo los ntawm ultraviolet (180 nm) mus rau infrared (8 μm).Lub qhov rais AR-coated muaj cov txheej txheem tiv thaiv kev cuam tshuam ntawm ob sab uas muab kev sib kis ntau ntxiv nyob rau hauv 1.65 - 3.0 µm teev wavelength ntau.Muab nws qhov tsis txaus nqus coefficient thiab muaj kev puas tsuaj loj, uncoated calcium fluoride siv lead ua yog ib qho kev xaiv nrov rau siv nrog excimer lasers.CaF₂Cov qhov rais kuj tseem siv tau rau hauv cov cua txias cua txias thermal imaging systems.Thov xyuas cov duab hauv qab no rau koj cov ntaub ntawv siv.
