Izinhlobo iwa-Ilensi yezimboniinsika

Kunezinhlobo ezine zezinhlobo ze-interface, okungukuthi i-F-Mount, C-Mount, C-Mount, CS-Mount kanye neM12 Mount. I-F-Mount iyisibonisi esibonakalayo esijwayelekile, futhi ngokuvamile ilungele ama-lens anesikhathi esiphezulu kune-25mm. Lapho ubude obugxile be-lens yenhloso bungaphansi kwama-25mm, ngenxa yosayizi omncane we-lens lenhloso, i-C-MANC noma i-CS-Mount iyasetshenziswa, futhi abanye basebenzisa isikhombimsebenzisi se-M12.

Umehluko phakathi kwe-C Mount and CS Mount

Umehluko phakathi kwezindawo zokuxhumana ze-C ne-CS ukuthi ibanga ukusuka endaweni yokuxhumana yelensi nekhamera kuya endizeni egxile kuyo ilensi (isikhundla lapho i-CCD Photolectric sensor yekhamera kufanele ihlukile. Ibanga lesibonisi se-C-Mound lingu-17.53mm.

Indandatho ye-adaptha engu-5mm C / CS CS ingangezwa kuma-lens we-CS-Mount Lens, ukuze isetshenziswe ngamakhamera we-C-Type.

Amapharamitha ayisisekelo amalensi wezimboni

Inkambu yokubuka (FOV):

I-FOV ibhekisa ebusweni obubonakalayo bento ebonakalayo, okungukuthi, ingxenye yento ethathwe inzwa yekhamera. (Ububanzi bensimu yokubuka yinto okufanele iqondwe ekukhetheni)

Inkambu yokubuka

Ibanga Lokusebenza (WD):

Kubhekisa ebangeni ukusuka phambili kusuka ngaphambili kwelensi kuya entweni evivinywa. Okungukuthi, ibanga elingaphezulu lokucabanga okucacile.

Isixazululo:

Usayizi wesici omncane ohlukile entweni ehloliwe engalinganiswa ngohlelo lokucabanga. Ezimweni eziningi, okuncane emkhakheni wokubuka, okungcono kwesinqumo.

Ukujula kokubukwa (dof):

Amandla welensi ukuze alondoloze isixazululo esifunekayo lapho izinto zisondele kakhulu noma zikude ngokugxila kakhulu.

Ukujula kokubukwa

Amanye amapharamitha weamalensi wezimboni

Usayizi we-chip chip:

Usayizi wendawo osebenzayo we-chip sensor yekhamera, ngokuvamile abhekisele kusayizi ovundlile. Le pharamitha ibaluleke kakhulu ukuthola ukukala kwelensi efanele ukuthola inkambu yokubuka oyifunayo. I-Lens Magnifisation Ratio (PMAG) ichazwa ngesilinganiso sobukhulu be-chip ye-chip emkhakheni wokubuka. Yize amapharamitha ayisisekelo afaka usayizi nomkhakha wokubuka kwe-chip e-chip, i-PMAG akuyona ipharamitha eyisisekelo.

Usayizi we-chip wezithombe

Ubude obugxile (f):

"Ubude obugxile kuyisilinganiso sokuhlushwa noma ukuhlukahluka kwesibani ohlelweni lwe-optical, olusho ibanga ukusuka esikhungweni se-optical of lens kuya kugxilwe ekubuthweni okukhanyayo. Futhi kuyibanga ukusuka enkabeni yelensi kuya endizeni ecabangayo efana nefilimu noma i-CCD kwikhamera. f = {Ibanga elisebenzayo / Inkambu yokubuka ohlangothini olude (noma uhlangothi olufushane)} »xccd side eside (noma uhlangothi olufushane)

Ithonya lobude obugxile: Ubude obugxile kakhulu, ubukhulu benkambiso; Uma kuncane ubude obugxile, kukhulu ukwahlukana; Uma kuncane ubude obugxile, obukhulu kakhulu ngento evumayo, enciphisa ukukhanyiselwa emaphethelweni e-afrrration.

Isixazululo:

Kukhombisa ibanga elincane phakathi kwamaphoyinti ama-2 angabonakala kusethi yama-lens we-onenhloso

I-0.61x esetshenzisiwe esetshenzisiwe (λ) / na = isinqumo (μ)

Indlela yokubala engenhla ingakwazi ukubala isisombululo, kepha akubandakanyi ukuhlanekezela.

※ I-wavength esetshenziswe yi-550nm

Ukuchazwa:

Inani lemigqa emnyama nomhlophe lingabonakala maphakathi ne-1mm. Iyunithi (lp) / mm.

I-MTF (I-Modation Transfel Work))

I-mtf

Ukuhlanekezela:

Enye yezinkomba zokukala ukusebenza kwamalensi ukuguquguquka. Kusho umugqa oqondile ngaphandle kwe-axis eyinhloko endizeni yendaba, eba yijika ngemuva kokufanelwa uhlelo lokubona. Iphutha lokucabanga kwalolu hlelo lwe-Optical libizwa ngokuthi ukuhlanekezela. Ukuhlanekezela kokuphazamiseka kuthinta kuphela i-geometry yesithombe, hhayi ubukhali besithombe.

I-Aperture nenombolo ye-F:

Ishidi le-lenticular yithuluzi elisetshenziselwa ukulawula inani lokukhanya elidlula ngelensi, imvamisa ngaphakathi kwelensi. Sisebenzisa inani le-F ukuveza usayizi we-apertate, njenge-F1.4, F2.0, F2.8, njll.

I-aperture nenombolo ye-f

Ukukhuliswa kwe-Optical:

Ifomula esetshenziselwa ukubala isilinganiso sokulinganisa esiphambili yile elandelayo: PMAG = Usayizi we-Sensor (MM) / Inkambu Yokubukwa (MM)

Khombisa ukukhula

Ukubukisa ukukhulisa kusetshenziswa kabanzi ku-microscopy. Ukukhuliswa kokubonisa kwento ephakeme kuncike ezicini ezintathu: ukunyuswa kwama-lens, usayizi we-chip ye-sensor yekhamera yezimboni (usayizi wendawo okuhlosiwe), nosayizi wesibuko.

Khombisa ukukhulisa = lens magnification magnification usayizi wokubonisa × 25.4 / usayizi we-diagonal

Izigaba eziphambili zamalensi wezimboni

Ukuhlela ngohlobo oluthile

• ngobude obugxile: Prime and zoom

• Ngokusebenzisa i-aperture: i-aperture engaguquki kanye ne-aperture eguquguqukayo

• Nge-interface: C interface, isikhombimsebenzisi se-CS, i-interface, njll.

• Ihlukaniswe ngama-multiplings: Ilensi yokukhulisa ehleliwe, i-lens eqhubekayo yokusondeza

• Amalensi abaluleke kakhulu asetshenziswa embonini yombono womshini ikakhulukazi afaka ama-Fales, ama-Telecentric lens kanye nama-microscopes wezimboni, njll.

Amaphuzu asemqoka okumele acabangele ekukhetheni aumshini wokubuka umshini:

1. Inkambu yokubukwa, ukukhulisa okubonakalayo kanye nebanga elisebenzayo lokusebenza

2. Ukujula kwezidingo zensimu: Ngoba amaphrojekthi adinga ukujula kwenkambu, asebenzise i-aperture encane ngangokunokwenzeka; Lapho ukhetha i-lens ngokukhulisa, khetha ilensi ngokukhulisa okuphansi kuze kufike lapho iphrojekthi ivumele. Uma izidingo zephrojekthi zifuna kakhulu, ngijwayela ukukhetha ilensi yokusika ngokujula okuphezulu.

I-3 usayizi we-sensor nesibonisi sekhamera: ngokwesibonelo, ilensi engu-2/3 "isekela i-lens enkulu kunazo zonke yekhamera yezimboni ingu-2/3, ayikwazi ukusekela amakhamera wezimboni akhulu kune-intshi eyi-1 inch.

4. Isikhala esitholakalayo: Akunangqondo kumakhasimende ukushintsha usayizi wemishini lapho uhlelo lungakhethwa.
