Iintlobo yeilensi yoshishinointaba

Kukho ubukhulu becala iintlobo ezine zojongano, ezizezi F-mount, C-mount, CS-mount kunye ne-M12 mount. I-F-Mount yi-interface yenjongo ngokubanzi, kwaye ifanelekile ngokubanzi kwiilensi ezinobude obugxininise ubude kune-25mm. Xa ubude benjongo ye-lens yenjongo bungaphantsi kwe-25mm, ngenxa yobukhulu obuncinci be-lens yenjongo, i-C-mount okanye i-CS-mount isetyenziswa, kwaye abanye basebenzisa i-interface ye-M12.

Umahluko phakathi kokunyuka kwe-C kunye nokunyuka kwe-CS

Umahluko phakathi kwe-C kunye ne-CS interfaces kukuba umgama ukusuka kwindawo yoqhagamshelwano ye-lens kunye nekhamera kwi-plane egxininisekileyo ye-lens (indawo apho i-CCD photoelectric sensor yekhamera kufuneka ibe khona) ihluke. Umgama we-C-mount interface yi-17.53mm.

I-5mm C / CS i-adapter ring inokongezwa kwi-CS-mount lens, ukwenzela ukuba isetyenziswe kunye neekhamera ze-C.

Iiparamitha ezisisiseko zeelensi zoshishino

Indawo yokujonga (FOV):

I-FOV ibhekisela kuluhlu olubonakalayo lwento ebonwayo, oko kukuthi, inxalenye yento ebanjwe yinzwa yekhamera. (Uluhlu lwendawo yokujonga yinto ekufuneka iqondwe kukhetho)

Indawo yokujonga

Umgama wokuSebenza (WD):

Ibhekisa kumgama osuka ngaphambili kwilensi ukuya kwinto ephantsi kovavanyo. Oko kukuthi, umgama ongaphezulu womfanekiso ocacileyo.

Isigqibo:

Olona phawu luncinci lunokwahlula ubungakanani kwinto ehloliweyo enokulinganiswa ngenkqubo yokucinga. Kwiimeko ezininzi, intsimi yokujonga encinci, ingcono isisombululo.

Ubunzulu bombono (DOF):

Ukukwazi kwelensi ukugcina isisombululo esinqwenelekayo xa izinto zikufutshane okanye zikude ukusuka kugxininiso olungcono.

Ubunzulu bombono

Ezinye iiparamitha zeiilensi zamashishini

Isayizi yetshiphu echukumisekileyo:

Ubungakanani bendawo esebenzayo ye-chip sensor yekhamera, ngokubanzi ibhekisa kubungakanani obuthe tye. Le parameter ibaluleke kakhulu ukumisela ukukala kwelensi ngokufanelekileyo ukufumana indawo efunwayo yokujonga. I-lens primary magnification ratio (PMAG) ichazwa ngumlinganiselo wobungakanani be-sensor chip kwintsimi yokujonga. Nangona iiparamitha ezisisiseko ziquka ubungakanani kunye nentsimi yokujonga i-photosensitive chip, i-PMAG ayiyona iparameter esisiseko.

Ubungakanani betshiphu obuchukumisekileyo

Ubude bokujongisisa (f):

“Ubude bokujongwa ngumlinganiselo wokugxininiswa okanye ukwahluka kokukhanya kwinkqubo yokukhanya, ebhekisa kumgama osuka kumbindi welensi ukuya kwindawo ekugxilwe kuyo ukukhanya. Ikwangumgama ukusuka kumbindi welensi ukuya kwinqwelomoya yomfanekiso njengefilimu okanye iCCD kwikhamera. f={umgama wokusebenza/ibala lokujonga icala elide (okanye icala elifutshane)}XCCD icala elide (okanye icala elifutshane)

Impembelelo yobude bogxininiso: incinci ubude bogxininiso, bukhulu ubunzulu bebala; okukhona kuncinci ubude bendawo, kokukhona kugqwetheka; incinci ubude befocal, kokukhona kubi kakhulu isenzeko se-vignetting, ethi icuthe ukukhanya kwincam yophambuko.

Isigqibo:

Ibonisa umgama omncinci phakathi kweengongoma ezi-2 ezinokubonwa ngeseti yeelensi zenjongo

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

Le ndlela yokubala ingentla ingabala isisombululo, kodwa ayibandakanyi ukugqwetheka.

※ Ubude bobude obusetyenzisiweyo yi-550nm

Inkcazo:

Inani lemigca emnyama nemhlophe lingabonwa phakathi kwe-1mm. Iyunithi (lp)/mm.

I-MTF (iModyuli yokuGqithisela umsebenzi)

Uphazanyiso:

Esinye sezibonakaliso zokulinganisa ukusebenza kwe-lens kukuphuma. Ibhekisa kumgca othe ngqo ngaphandle kwe-axis ephambili kwindiza yesifundo, ejika ibe yigophe emva kokuba iboniswe yinkqubo yokukhanya. Impazamo yokucinga yale nkqubo yokukhanya ibizwa ngokuba yi-distortion. Ukuphambuka kokuphazamiseka kuchaphazela kuphela ijometri yomfanekiso, hayi ububukhali bomfanekiso.

Umngxuma kunye nenombolo F:

I-lenticular sheet sisixhobo esisetyenziselwa ukulawula ubungakanani bokukhanya okudlula kwilensi, ngokuqhelekileyo ngaphakathi kwilensi. Sisebenzisa ixabiso le-F ukuvakalisa ubungakanani bokuvula, njenge-f1.4, F2.0, F2.8, njl.

Umngxuma kunye nenombolo F

Ukwandiswa kwamehlo:

Ifomula esetyenziswayo ukubala umlinganiselo ongundoqo wokukala umi ngolu hlobo lulandelayo: PMAG = ubungakanani boluvo (mm) / indawo yokujonga (mm)

Bonisa ukwandiswa

Ukwandiswa komboniso kusetyenziswa kakhulu kwimicroscope. Ukwandiswa komboniso wento elinganisiweyo kuxhomekeke kwizinto ezintathu: ukukhuliswa kwe-optical ye-lens, ubukhulu be-sensor chip yekhamera yoshishino (ubungakanani bomgangatho ojoliswe kuyo), kunye nobukhulu bomboniso.

Bonisa ukwandiswa = ukwandiswa kwelensi yokukhanya × ubungakanani bomboniso × 25.4 / ubungakanani beraki yediagonal

Iindidi eziphambili zeelensi zamashishini

Ukuhlelwa

•Ngobude bojoliso: ubukhulu kunye nokwandisa

•Ngomngxuma wokuvula: umngxuma ongaguquguqukiyo

•Ngojongano: C interface, CS interface, F interface, njl.

•Ukwahlulwe ngophindaphindo: ilensi yokwandisa okusisigxina, ilensi yokwandisa eqhubekayo

•Ezona lens zibaluleke kakhulu eziqhele ukusetyenziswa kushishino lombono womatshini ikakhulu zibandakanya iilensi ze-FA, iilensi zocingo kunye neemicroscopes zamashishini, njl.

Amanqaku aphambili ekufuneka athathelwe ingqalelo ekukhetheni aIlensi yombono womatshini:

1. Intsimi yokujonga, ukukhuliswa kwe-optical kunye nomgama ofunekayo wokusebenza: Xa ukhetha i-lens, siya kukhetha i-lens kunye nentsimi yembono enkulu kunento ekufuneka ilinganiswe, ukwenzela ukuba kube lula ukulawula ukunyakaza.

2. Ubunzulu beemfuno zentsimi: Kwiiprojekthi ezifuna ubunzulu bentsimi, sebenzisa indawo yokuvula encinci kangangoko kunokwenzeka; xa ukhetha i-lens enokwandiswa, khetha i-lens enokwandiswa okuphantsi kangangoko iprojekthi ivumela. Ukuba iimfuno zeprojekthi zifuna kakhulu, ndihlala ndikhetha i-lens ye-cutting-edge enobunzulu obuphezulu bentsimi.

3. Ubungakanani boluvo kunye nojongano lwekhamera: Umzekelo, i-2/3″ lens ixhasa eyona ndawo inkulu yekhamera yerakhi yi-2/3 ″, ayinakuxhasa iikhamera zoshishino ezinkulu kune-intshi enye.

4. Indawo ekhoyo: Akukho ngqiqweni ukuba abathengi batshintshe ubungakanani besixhobo xa iskimu sinokuzikhethela.
