Chii chinonzi interference filters?

1. Chii chinonzi sefa?
Mafirita emaziso, sekureva kunoita zita, malenzi anosefa mwenje.Iyo inozivikanwawo se "polarizer", chinhu chinowanzoshandiswa mukutora mifananidzo.Iyo ine zvidimbu zviviri zvegirazi, ine dhizaini yekunzwa kana zvimwe zvakafanana zvakaiswa pakati pavo, uye kuburikidza nekufambisa uye kuratidzwa kwechiedza pane inonzwa, chiitiko chinoshandurwa muchiedza uye mumvuri.

Chii chinonzi mafirita

2. Nheyo yekusefa
Sefa inogadzirwa nepurasitiki kana girazi uye inowedzerwa nedhayi dzakakosha.Iyo tsvuku sefa inogona kungopfuura mwenje mutsvuku, zvichingodaro.Kufambiswa kwepepa regirazi kwakafanana nekwemhepo pakutanga, uye chiedza chese chine mavara chinogona kupfuura, saka chiri pachena, asi mushure mekudhaya, chimiro chemolecular chinoshanduka, iyo refractive index inoshandukawo, uye kupfuura kweimwe chiedza-kudzivirira. zvinhu zvinoshanduka.Semuenzaniso, kana mwenje wechiedza chichena ukapfuura nepasefa yebhuruu, mwenje weblue unoburitswa, ukuwo mwenje mudiki uye tsvuku unoburitswa, uye mazhinji acho anotorwa nesefa.

3. Basa resefa
Mukutora mifananidzo, mafirita anoshandiswa kune dzakasiyana siyana zvidzidzo, senge nyika, mapikicha, uye hupenyu huchiripo.Iyi inotevera sumo pfupi yekushanda kwesefa:
1) Dzora musiyano (kureva chiedza uye rima musiyano) wemufananidzo nekushandura kona yechiedza chechiitiko kuti ujekese nyaya.
2) Shandisa akasiyana mavara mafirita uye lens chromatic aberration kugadzirisa kuyera kwemavara emufananidzo.
3) Kuti uwane chaiyo hunyanzvi mhedzisiro nekusarudza akasiyana mavara mafirita.
4) Gadzirisa kukosha kwekuvhura kana kureba kwekutarisa sezvinodiwa kuti uwane yakakosha mhedzisiro.
5) Shandisa segirazi rinodzivirira.
6) Kana lenzi yekamera yakasviba, inoshandiswa pakuchenesa.
7) Inoshandiswa se teleconverter.
8) Inoshandiswa se polarizer.
