Yintoni mkhulu okuphambili? Tips for Ukukhetha

Hayi kudala, iingcali wamazinyo, bejewellery, beemaphu, iinjineli elektroniki ziye ngokubanzi kusetyenziswa okuphambili mkhulu kunye nokukhanya. Kweli nqaku siza kuhlolisisa imiba njengezona nkalo zitshisa ibunzi ezivelayo ekukhetheni sixhobo a ezizodwa.

ukwandisa

Standard okuphambili lens umntu ukukhulisa izihlandlo 2.5. Imfuno njengezibonelo abanjalo kuphela bamazinyo, kodwa nakwezinye iinkalo amayeza. Oku kwanda lisebenza okuhle kuphela kwabasaqalayo kodwa kubasebenzisi abaphambili.

Kwezinye iindawo, ezifana zobunjineli bombane kunye microsurgery, kufuna mkhulu binocular okuphambili abanesidanga eliphezulu sikrini. Xa iingcinga yemveliso advanced uthe sibalo ngaphezu kwe parameter eqhelekileyo ka-6.

focus

Okuphambili sokukhulisa kufuneka zikhethwe kuxhomekeke kumgama yokusebenza kunye uluhlu apho umfanekiso ukhaliphile. Okwangoku le yeemalike yokusebenza izixhobo umgama leyo uluhlu mm ukusuka 250 ukuya 520. Ukukhethwa yesisombululo eliphezulu kuxhomekeke nje kuphela umgangatho ngokubanzi imveliso, esibonakala okuphambili lens, kodwa ke uhlobo ukusetyenziswa kwefowuni kunye neemfuno lomsebenzisi.

Ke ubunzulu ekujoliswe, uyakwazi ukubona i index ngokulinganisa zikude kufuphi indawo apho umfanekiso igcina sharpness walo. umsebenzi sokukhulisa okuphambili ikuvumela ukuba ukudala ugxininiso efunekayo ngokutshintsha izicwangciso.

emehlweni

Apha uthetha indawo ofuna ubone ngokucacileyo indlela yokusebenza ye ifowuni xa esenza umsebenzi othile. Okuphambili lens ukunika ebanzi intsimi lwembono, kufuneka sinikele ingqalelo iintlobo ezaziwayo imveliso. Ergonomics imifuziselo zitshiphu yenza amava lomsebenzisi kakuhle.

I angle of utyekelo

Ukongezelela okuphambili lensi yaba lula kakhulu ukuba ukusebenzisa, kuyimfuneko ukuba banikele ingqalelo izixhobo kunye ukukwazi ukutshintsha le engela ukuthambekela.

Ngoko ke, ukuba usebenzisa isixhobo umsebenzisi kufuneka ukuthoba kwesilevu, ebonisa ukungabikho ukuthambekela khulu. Xa ngexesha lokusebenza kwefowuni kwakhiwe, umfanekiso ocacileyo ebukhali kuyimfuneko ukuze ulahle umva intloko - i-engile utyekelo uzisebenzisa.

Isisombululo elifanelekileyo izenzo okuphambili iSandisi, engaquki nyanzela umsebenzisi zizame amehlo akho nentamo kule nkqubo.

ukukhanyisa

kusetyenziswa izinto LED ukukhanyisa ngokuyintloko epheleleyo loupes isibane. Ngokukodwa, izibane yafakwa wanika ukukhanya kakhulu umfaniswano omhlophe oko akubangeli eyestrain.

Headlamps iSandisi, ezisetyenziswa entsimini bamazinyo, basoloko mayixhotyiswe filter umbala otyheli. Ukuqaliswa ezinemiqadi echweliweyo yemisedare phezu izinto elastic labalandeli akubangeli ephilisa kwexesha.

Noko ke, nkqu LED aqaqambe, zicwangciswe ngendlela embi, bakwazi ukushiya izithuba mbane. Ukunqanda ukuphazamiseka ezinjalo, kufuneka ukunika izixhobo kuqala isibane kunye nezibane, ezisisigxina bridge umsebenzisi.

amacebo aluncedo

Xa uthenga i ebunzi khulu kuyimfuneko ukunikela ingqalelo ezi ngcebiso zilandelayo:

1. Okokuqala, kufuneka amisele inqanaba yongeniselo. I ezincinane ixabiso, kokukhona ingcaciso yomfanekiso enkundleni ebanzi ingxelo view.
2. Ukukhetha le khulu ngokuvumelana yomgama elisebenzayo kufuneka zenziwe ukwaneza iimfuno zomntu ngamnye kunye nokusingqongileyo yokusebenza.
3. Lula kokusebenzisa ebunzi khulu kuxhomekeke kudidi sothimbo. Oku kunokuba urhangqo eqhelekileyo, isakhelo ergonomic okanye ntloko.
4. Kubaluleke kakhulu xa usebenzisa mkhulu kufeza eyakhelwe-yafakwa ukhanyiso, apho ukukhanya ngokukodwa kwaye ukujikelezisa egxile.

buhle

loupes isibane babe yonke eninzi amathuba xa kuthelekiswa izixhobo ukhulise manual. Okokuqala zonke izixhobo kolu didi ezandleni umsebenzisi ngesisa. Devices ne ilayithi zilungele ukuba iibhodi wesekethe eziprintiweyo, izibambi, enze imikrolo zintle, nezimfakamfele.

Zizixhobo kakhulu ezisebenzayo zinika ithuba elaneleyo lokuba ukunyenyisa ingqalelo,-engile ukuthambeka ukuba bukhali. Ezinye iimodeli baxhotyiswa kunye isalathisi laser, nto leyo evumela ukuba kugxininisa kwinxalenye efanelekileyo kwinkqubo yokwenza umsebenzi.
