Nheyo yekushanda, hunhu uye mashandisirwo eDouble-Pass Filters

Seimwe mhando ye optical filter, double-passsefa(inozivikanwawo se transmission filter) chishandiso che optical chinogona kuendesa kana kuratidza chiedza nenzira yakasarudzwa munzvimbo yakatarwa ye wavelength. Chinowanzo unganidzwa nezvikamu zviviri kana kupfuura zvemafirimu matete, chimwe nechimwe chine hunhu hwacho hwe optical. Chine transmittance yakakura mukati mezvikamu zviviri zve wavelength, uye chine hunhu hwekuvhara mune zvimwe zvikamu zve wavelength pakati pezvikamu zviviri izvi.

1.Musimboti wekushandayemafirita maviri

Pfungwa yekushanda kwefirita ine ma "double-pass" inonyanya kuenderana nemhedzisiro yekupindira kwefirimu ine ma "multi-layer". Kana chiedza chikapinda mufirita, chinokanganisa ma "layer" akasiyana efirimu. Nekugadzira nekudzora ukobvu uye refractive index yefirimu, zvinokwanisika kutumira kana kuratidza chiedza chewavelength chaiyo.

Zvikuru sei, kana kureba kwechiedza chechiitiko kuchienderana nehukuru hwewavelength hunoshandiswa nedhizaini yefirita, chiedza chewavelength imwechete chichawedzerwa mukati mefirita kuburikidza nehukuru hwemukati, zvichiita kuti ipfuure nepakati pefirita. Kusiyana neizvi, chiedza chewavelength dzakasiyana chichaparadzwa nehukuru hwewavelength uye chichatorwa kana kuratidzwa nefirita.

Kutumira kana Kufungisisa Kwekusarudza

Zvichibva pakugadzira uye kusarudzwa kwezvinhu, pfuura kavirimafiritainogona kuendesa kana kuratidza chiedza nenzira yakasarudzwa mukati mehuwandu hwakatarwa hwewavelength.

Kujeka kwakanyanya

Mubhendi rekutumira rakasarudzwa, kutumirwa kwefirita rema "double-pass" kunogona kusvika kupfuura 90%, izvo zvinogona kusarudza nemazvo kutumira kana kuvhara marefu echiedza.

Kushanda zvakanaka kwazvo

Mafirita anopfuudzwa kaviri anogona kuita kuti chiedza chivheneke zvakanyanya kana kuti chivheneke zvakanyanya, zvichiita kuti akwanise kushanda zvakanaka nekugadzirisa chiedza mumasisitimu e optical; panguva imwe chete, mashandiro awo haanyanyi kuchinja kana paine shanduko dzezvakatipoteredza dzakadai setembiricha nehunyoro, uye ane insulation yakanaka uye anodzivirira ngura, uye anogona kushanda zvakanaka kwenguva yakareba.

Kupasa kavirimafiritaine bandwidth yakamanikana yechiedza mukati mehuwandu hwakatarwa hwewavelength, zvichipa sarudzo yepamusoro yespectral.

3.Mashandisirwo emafirita ekushandisa kaviri

Mafirita ekushandisa kaviri anoshandiswa zvakanyanya muminda yakawanda, senge:

Zvishandiso zveOptical

Mafirita e "double-pass" anowanzo shandiswa muzvishandiso zve optical zvakaita se spectrometers, maikorosikopu, uye ma lasers kuti abvise kana kuburitsa chiedza che wavelengths chaiyo.

Inoshandiswa muzvishandiso zve optical

Zvishandiso zvetekinoroji yekutaurirana

Mafirita e "double-pass filters" anoshandiswa muminda yekutaurirana ne "optical fiber", zvishandiso zve "optomechanical", nezvimwewo kuti kuvandudza kunaka kwekutaurirana. Semuenzaniso, mumasisitimu ekutaurirana ne "optical fiber", mafirita e "double-pass filters" anonyanya kushandiswa kusefa chiedza che "wavelengths" chaiyo yekutumira uye kuwedzera masaini e "optical".

Mapurogiramu ekuchengetedza ruzivo rwemaziso

Mumidziyo yekuchengetera magirazi, mafirita anopfuudzwa kaviri anonyanya kushandiswa kuverenga kana kunyora zviratidzo zvemagirazi chaiwo.

Mashandisirwo eRaman spectroscopy akawedzerwa pamusoro

Zvinoshandiswa muRaman spectroscopy yakasimbiswa pamusoro, mafirita anopfuudzwa kaviri anowana zviratidzo zveRaman zvema wavelengths chaiwo nekusarudza kuratidzira kana kutumira.

Pamusoro pezvo, double-passmafiritaZvinoshandiswawo muminda yesainzi yehupenyu yakadai seye biological microscopy uye fluorescent probe detection, izvo zvinogona kuita kuti zvionekwe nemazvo uye zvionekwe nemazvo.
