Isahani yamashanyarazi

Amashanyarazi ni ibice bya optique bigabanya urumuri mubyerekezo bibiri.Kurugero mubisanzwe bikoreshwa muri interterometero kugirango urumuri rumwe rwivange ubwacyo.Muri rusange hari ubwoko butandukanye bwibiti: isahani, cube, pellicle na polka akadomo.Igikoresho gisanzwe kigabanya urumuri ku ijanisha ryimbaraga, nko kwanduza 50% no kugaragariza 50% cyangwa kwanduza 30% no kwerekana 70%.Imirasire idafite polarize igenzurwa byumwihariko kugirango idahindura imiterere ya S na P yumucyo winjira.Polarizing beamsplitters izohereza urumuri rwa P polarize kandi rugaragaze urumuri rwa S polarize, bizemerera abakoresha kongeramo urumuri rwa polarisiyumu muri sisitemu optique.Dichroic beamsplitters igabanya urumuri kuburebure bwumuraba kandi bikunze gukoreshwa mugukoresha fluorescence mugutandukanya inzira yo kwishima no gusohora.

Nubwo amashanyarazi adafite polarisiyoneri yagenewe kudahindura imiterere ya S na P ya polarisiyasi yumucyo winjira, baracyumva urumuri rwa polarisiyasi, bivuze ko hazakomeza kubaho ingaruka zimwe na zimwe za polarisiyasi niba itara ridafite polarisiyumu ryahawe urumuri rwinjiza rudasanzwe. .Icyakora, amatara yacu ya depolarizing ntabwo azumva neza polarisiyasi yibyabaye, itandukaniro ryo gutekereza no kwanduza S- na P-pol.ni munsi ya 5%, cyangwa ntanubwo hari itandukaniro mugutekereza no guhererekanya kuri S- na P-pol kumurongo runaka wuburebure.Nyamuneka reba ibishushanyo bikurikira kugirango ubone.

Paralight Optics itanga intera nini ya optique yamashanyarazi.Isahani yacu yamashanyarazi ifite ubuso bwimbere bugaragaza igipimo cyo kugabana ibiti mugihe ubuso bwinyuma bwashizwe hamwe na AR igashyirwaho kugirango hagabanuke ingaruka ziterwa no kuzimu.Cube beamsplitters iraboneka muburyo bwa polarisiyasi cyangwa idafite polarize.Pellicle beamsplitters itanga uburyo bwiza bwo gukwirakwiza mugihe cyo gukuraho ibiti no kuzimu.Dichroic beamsplitters yerekana imirasire yerekana imirasire yuburebure.Ni ingirakamaro mu guhuza / gutandukanya ibiti bya laser byamabara atandukanye.
