Iintlobo yeilensi yemizi-mvelisokhwelisa

Kukho iintlobo ezine eziphambili ze-interface, ezizezi: i-F-mount, i-C-mount, i-CS-mount kunye ne-M12 mount. I-F-mount yi-interface yeenjongo ezibanzi, kwaye ifanelekile ngokubanzi kwiilensi ezinobude obuphezulu obungaphezulu kwe-25mm. Xa ubude obuphezulu be-lens ye-objective bungaphantsi kwe-25mm, ngenxa yobukhulu obuncinci be-lens ye-objective, kusetyenziswa i-C-mount okanye i-CS-mount, kwaye abanye basebenzisa i-interface ye-M12.

Umahluko phakathi kwe-C mount kunye ne-CS mount

Umahluko phakathi kwe-C kunye ne-CS interfaces kukuba umgama ukusuka kumphezulu woqhagamshelwano lwelensi kunye nekhamera ukuya kwindawo egxile kuyo ilensi (indawo apho kufuneka ibekwe khona i-CCD photoelectric sensor yekhamera) wahlukile. Umgama we-C-mount interface yi-17.53mm.

Indandatho ye-adaptha ye-5mm C/CS ingongezwa kwilensi ye-CS-mount, ukuze isetyenziswe neekhamera zohlobo lwe-C.

Iiparameter ezisisiseko zeelensi zemizi-mveliso

Indawo yokujonga (FOV):

I-FOV ibhekisa kuluhlu olubonakalayo lwento ebonwayo, oko kukuthi, inxalenye yento ethathwe sisiva sekhamera. (Uluhlu lwentsimi yokujonga yinto ekufuneka iqondwe ekukhetheni)

Umbono wenkundla

Umgama Wokusebenza (WD):

Ibhekisa kumgama ukusuka ngaphambili kwelensi ukuya kwinto evavanywayo. Oko kukuthi, umgama womphezulu womfanekiso ocacileyo.

Isisombululo:

Ubungakanani obuncinci bophawu olubonakalayo kwinto ehlolwayo obunokulinganiswa yinkqubo yomfanekiso. Kwiimeko ezininzi, okukhona intsimi yombono incinci, kokukhona isisombululo singcono.

Ubunzulu bombono (DOF):

Amandla elensi okugcina isisombululo esifunekayo xa izinto zikufutshane okanye zikude kakhulu nendawo ekugxilwe kuyo.

Ubunzulu bombono

Ezinye iiparameter zeiilensi zoshishino

Ubungakanani betshiphusi ebuthathaka kwifoto:

Ubungakanani bendawo esebenzayo yetshiphu yesenzwa yekhamera, ngokubanzi ibhekisa kubungakanani obuthe tye. Le parameter ibaluleke kakhulu ekumiseleni isikali seelensi esifanelekileyo ukuze kufunyanwe intsimi yombono oyifunayo. Umlinganiselo wokukhulisa i-lens primary magnification (PMAG) uchazwa ngumlinganiselo wobungakanani betshiphu yesenzwa kwintsimi yombono. Nangona iiparameter ezisisiseko ziquka ubungakanani kunye nentsimi yombono wetshiphu ebona ukukhanya, iPMAG ayisiyo parameter esisiseko.

Ubungakanani betshiphusi ebuthathaka kwifoto

Ubude befokhalthi (f):

"Ubude befocal buyindlela yokulinganisa ukugxila okanye ukuhlukana kokukhanya kwinkqubo ye-optical, ebhekisa kumgama ukusuka kwiziko le-optical lelensi ukuya kwindawo ekuqokelelwa kuyo ukukhanya. Ikwangumgama ukusuka embindini welensi ukuya kwindawo yokufota efana nefilimu okanye i-CCD kwikhamera. f={umgama osebenzayo/intsimi yokujonga icala elide (okanye icala elifutshane)}Icala elide le-XCCD (okanye icala elifutshane)

Impembelelo yobude befocal: okukhona ubude befocal buncinci, kokukhona ubunzulu bentsimi bubukhulu; okukhona ubude befocal buncinci, kokukhona ukuphambuka kukhulu; okukhona ubude befocal buncinci, kokukhona into ebangela ukudinwa inzima, nto leyo enciphisa ukukhanya kumda wokuphazamiseka.

Isisombululo:

Ibonisa umgama omncinci phakathi kwamanqaku ama-2 anokubonwa liqela leelensi ezijolise ngqo

I-0.61x ubude bexesha obusetyenzisiweyo (λ) / NA = isisombululo (μ)

Indlela yokubala engentla ingayibala ngokwethiyori isisombululo, kodwa ayibandakanyi ukugqwethwa.

※Ububanzi bomda obusetyenzisiweyo yi-550nm

Inkcazo:

Inani lemigca emnyama nemhlophe lingabonakala embindini we-1mm. Iyunithi (lp)/mm.

I-MTF (Umsebenzi wokudlulisa iModulation)

I-MTF

Uphazanyiso:

Esinye sezibonakaliso zokulinganisa ukusebenza kwelensi kukungaqondi. Sibhekisa kumgca othe tye ongaphandle kwe-axis ephambili kwiplane yomntu ochaphazelekayo, ojika ube yigophe emva kokuba umfanekiso uthathwe yinkqubo yokujonga. Impazamo yokujonga le nkqubo yokujonga ibizwa ngokuba yi-distortion. Ukungaqondi kakuhle kuchaphazela kuphela i-geometry yomfanekiso, kungekhona ubukhali bomfanekiso.

Imbobo kunye neNombolo ye-F:

Iphepha le-lenticular sisixhobo esisetyenziselwa ukulawula ubungakanani bokukhanya okudlula kwilensi, ngesiqhelo ngaphakathi kwilensi. Sisebenzisa ixabiso le-F ukubonisa ubungakanani be-aperture, njenge-f1.4, F2.0, F2.8, njl.

Imbobo kunye neNombolo ye-F

Ukwandiswa kokukhanya:

Ifomula esetyenzisiweyo ukubala umlinganiselo oyintloko wokulinganisa yile ilandelayo: I-PMAG = ubungakanani besenzi (mm) / intsimi yokujonga (mm)

Ukwandiswa komboniso

Ukwandiswa kwesiboniso kusetyenziswa kakhulu kwi-microscopy. Ukwandiswa kwesiboniso sento elinganisiweyo kuxhomekeke kwizinto ezintathu: ukwandiswa kwelensi, ubungakanani be-sensor chip yekhamera yemizi-mveliso (ubungakanani bomphezulu ekujoliswe kuwo), kunye nobukhulu besiboniso.

Ukwandiswa kwesiboniso = ukwandiswa kwelensi optical × ubungakanani besiboniso × 25.4 / ubungakanani be-diagonal yereki

Iindidi eziphambili zeelensi zemizi-mveliso

Ulwahlulo

•Ngobude befocal: iprime kunye ne-zoom

•Ngomngxuma: umngxuma ozinzileyo kunye nomngxuma oguquguqukayo

•Ngojongano: ujongano lwe-C, ujongano lwe-CS, ujongano lwe-F, njl.

•Yahlulwe ngee-multiples: ilensi yokukhulisa engaguqukiyo, ilensi yokusondeza eqhubekayo

•Iilensi ezibaluleke kakhulu ezisetyenziswa kakhulu kushishino lombono womatshini ziquka iilensi ze-FA, iilensi ze-telecentric kunye nee-microscopes zoshishino, njl.njl.

Amanqaku aphambili ekufuneka aqwalaselwe xa ukhethailensi yombono womatshini:

1. Indawo yokujonga, ukukhulisa okubonakalayo kunye nomgama ofunekayo wokusebenza: Xa sikhetha ilensi, siza kukhetha ilensi enommandla wokujonga omkhulu kancinci kunento eza kulinganiswa, ukuze kube lula ukulawula intshukumo.

2. Ubunzulu beemfuno zentsimi: Kwiiprojekthi ezifuna ubunzulu bentsimi, sebenzisa umngxuma omncinci kangangoko kunokwenzeka; xa ukhetha ilensi enokukhulisa, khetha ilensi enokukhulisa okuphantsi kangangoko iprojekthi ivuma. Ukuba iimfuno zeprojekthi zinzima ngakumbi, ndikhetha ilensi yanamhlanje enobunzulu bentsimi.

3. Ubungakanani benzwa kunye nojongano lwekhamera: Umzekelo, ilensi ye-2/3″ ixhasa umphezulu omkhulu werekhi yekhamera yemizi-mveliso yi-2/3″, ayinakuxhasa iikhamera zemizi-mveliso ezinkulu kune-intshi enye.

4. Indawo ekhoyo: Akukho ngqiqweni ukuba abathengi batshintshe ubungakanani bezixhobo xa inkqubo ingenasibophelelo.
