Ọrụ nke diaphragm n'ime Sistemụ ngwa anya

Ọrụ ndị bụ isi nke oghere n'ime sistemu ngwa anya gụnyere ịmachi oghere oghere, mmachi mpaghara nlele, ịkwalite ogo onyonyo, na iwepụ ìhè kpafuru akpafu, n'etiti ndị ọzọ. Kpọmkwem:

1. Ịkwụsị oghere Beam: Aperture na-ekpebi ọnụọgụ ọkụ na-abanye n'ime usoro ahụ, si otú ahụ na-emetụta ìhè na mkpebi nke ụgbọelu ihe oyiyi. Dịka ọmụmaatụ, diaphragm okirikiri dị na oghere igwefoto (nke a na-akpọkarị oghere) na-eje ozi dị ka oghere oghere nke na-amachibido nha ntuhie ahụ merenụ.

2. Mgbochi Ulo Nlele: A na-eji mpaghara nlele anya diaphragm iji kpachie oke onyonyo a. Na usoro foto, ihe nkiri ahụ na-arụ ọrụ dị ka diaphragm dị n'ọhịa, na-egbochi ihe oyiyi nke nwere ike ịmepụta na oghere ihe.

3. Ịkwalite ogo onyonyo: Site n'itinye diaphragm n'ụzọ kwesịrị ekwesị, aberrations dị ka spherical aberration na coma nwere ike ibelata, si otú ahụ na-emeziwanye àgwà foto.

4. Na-ewepụ Ìhè Anya: The diaphragm na-egbochi ìhè na-abụghị nke eserese, si otú ahụ na-eme ka ọdịiche dị. A na-eji diaphragm mgbochi akpafuo iji gbochie agbasasị ma ọ bụ mụbaa ìhè na-egosipụta ma bụrụ nke a na-ahụkarị na sistemu ngwa anya dị mgbagwoju anya.

Nkewa nke diaphragms gụnyere ihe ndị a:

Aperture Diaphragm: Nke a na-ekpebi ozugbo oghere oghere nke oghere onyonyo n'otu ebe na axis ma marakwa dị ka diaphragm dị irè.

Ubi Diaphragm: Nke a na-amachi oke oghere nke onyonyo enwere ike ịmepụta, dịka n'ihe gbasara etiti ihe nkiri igwefoto.

Mgbochi mkpọtụ Diaphragm: A na-eji nke a egbochi ọkụ gbasasịa ma ọ bụ mụbaa ìhè na-egosipụta, si otú ahụ na-eme ka ọdịiche na doo anya nke usoro ahụ.

Ụkpụrụ ọrụ na ọrụ nke diaphragm na-agbanwe agbanwe na-adabere n'ikike ya iji chịkwaa ọkụ ọkụ na-agafe site n'ịgbanwe nha oghere. Site n'ịtụgharị ma ọ bụ na-amịgharị agụba diaphragm, enwere ike imezi nha oghere ahụ mgbe niile, na-eme ka njikwa nke ọma na oke ọkụ. Ọrụ nke diaphragm na-agbanwe agbanwe gụnyere ịhazigharị mkpughe, ịchịkwa omimi nke ubi, ichebe oghere, na ịkpụzi osisi, n'etiti ndị ọzọ. Dịka ọmụmaatụ, n'okpuru ọnọdụ ọkụ siri ike, ibelata oghere n'ụzọ kwesịrị ekwesị nwere ike ibelata ọkụ ọkụ na-abanye na oghere, si otú a gbochie mmebi nke oke nhụsianya kpatara.
