Indlela ukukhetha isibonakhulu isitshudeni?

Uhlu izipho best for umntwana kufanele nakanjani zihlanganisa imishini for ucwaningo lwesayensi. Yiqiniso, sikhuluma mayelana amateur futhi, ngaphezu kwalokho, nezinga lezingane yokutadisha zomhlaba ezizungezile. Kodwa ukubeka into eziyibonayo umfundi base kuyoba okwanele. Omunye ongakhetha imishini ezithakazelisayo kakhulu futhi asebenziseka kalula-esinjalo ngesibonakhulu. onobuhle yamanje organically sihlanganise lula ukusetshenziswa kanye nokusebenza kuqhathaniswa eliphezulu. Noma kunjalo, ukuthola indlela ukukhetha microscope kumfundi, kufanele ucabangele izilungiselelo ezahlukene umshini. Nakuba abakhiqizi ukukhulula umugqa olukhethekile onobuhle zezingane, ngisho phakathi lezi izinqumo kungaletha ubunzima ezithile.

Kuyini onobuhle enezingane ezinezidingo ezikhethekile sika?

Ngokuvamile izingane analogs imishini kanye nempahla senzelwe abadala sibaphatha lula ukwakhiwa. Ngokwengxenye lokhu kuyiqiniso ngoba nangezibonakhulu, nakuba iqoqo izingxenye ingxenye esetshenziswa kuyafana - kungcono eyepiece umnikazi, Tuba, amalensi, futhi olunamagama esiteji. Kuye imodeli, ngoba ngesibonakhulu umfundi kungaba izindlela ezihlukene salezi zici, kodwa zonke igxile ukuxhashazwa ezingeni kokuqala eyinkimbinkimbi.

Kufanele kukhunjulwe ukuthi umfuziselo ezinjalo ngeke kuqhathaniswe namadivayisi ephezulu siGaba kaningi okwandisa. Izinga ubuncane kulolu khetho ezingu-40 eshumini, futhi ingxenye phakathi amadivayisi zezingane kungenziwa amadivayisi atholakele nge 600-nesibaya isikhulisi. Ukukhethwa lesi sici kumele kwenziwe, ngokusekelwe ukusetshenziswa imibuzo. Ngaphezu kwalokho, i-microscope umfundi kungahluka ezicashile design obonakaliswe ngesimo imiklamo kanye nemibala. Ungakhohlwa ukuthi sikhuluma nezingane, kanye nokusebenza sangaphandle microscope nalo libalulekile.

Izinhlobo nangezibonakhulu ngoba umfundi

Kusengenzeka amamodeli ezivamile electronic, okuyinto anemisila electrostatic lens kazibuthe. Kodwa lokhu apharathasi akakwazi ngokuthi ukuqeqeshwa, ngoba kungenzeka eliphezulu ukwanda, okungase izandla umfundi ngokweqile. apparatuses Ngokuvamile monocular ekhethelwe ukusetshenziswa okunjalo, ezithinta elingeyona inkimbinkimbi, kodwa ngesikhathi esifanayo yokubhekana nezinkinga yenqubo yokufunda. Enwetshiwe begazi isibonakhulu wesikole izibuyekezo athi ukusebenza namathuba isifundo amaseli. Mhlawumbe kakhulu ubuchwepheshe kungenziwa ngokuthi idivayisi stereoscopic okuyinto ifakwe eyepieces ezimbili. Le modeli ikhange hhayi kuphela observation elula into lafundvwako, kodwa khona ukukhanya, esihlinzeka izinga sobala isithombe lens.

onobuhle Digital

ukunakekelwa okukhethekile unikezwa idivayisi digital. Ngokushesha kufanele kuphawulwe ukuthi kukhona le-microscope is ezibizayo okuningi kuka nozakwabo bendabuko, kodwa ukusebenza yayo kuyazuzisa yini ngempela. Isici zedivayisi yikhono ukuxhuma ikhompyutha noma i-camcorder nge esibonakalayo se-USB. Lokhu kusho ukuthi ngesibonakhulu digital isitshudeni kungaba ngokuqondile uthumele Imiphumela observation kwimidiya ekhethekile. Ngokuvamile, ukuhlela kabusha enjalo anemisila ekhombisa digital nokukhanya kwasemuva LED. Ukuze bazifundise inketho kulabo ukuthi umfundi uzokwazi kalula kahle kudivayisi ukusebenza enjalo, futhi ikhono ukurekhoda izinto kuzovumela ukuqhubeka nesifundo, ngisho emva kokuphothulwa umsebenzi nedivaysi.

Yini okufanele icatshangelwe inqubo Ukukhetha?

Okokuqala, kufanele sicabangele izinga ukusebenza kanye iphuzu impahla umbono. Leli bhokisi kungenzeka plastic noma insimbi. amapulasitiki Modern okuhlala, kodwa futhi ivumela isisindo umkhiqizo ukukhanya. Metal kudivayisi okuhlala isikhathi eside, kodwa kunzima kakhulu ukuba ingane ukusingatha. Amalensi eyepieces kufanele kwenziwe ngengilazi - engathatha ezishibhile ngendlela plastic kuyaqabukela inikeza izinga ezinhle. Ngokulinganiswa kaningi sekushiwo ukuthi nangezibonakhulu abafundi bakwazi ukwandisa emehlweni akhe e-avareji yezikhathi 40 kuya kwangu-600. Kukhona amamodeli ukuthi unikeze isilinganiso ephakeme, kodwa akudingekile ezingeni lesikole. kubaluleke kakhulu ukucabangela usizo zedivayisi. Ngokwesibonelo, ukukhanyisa kungcono ukukhetha okusekelwe diodes ukukhanya-likhipha, futhi esigabeni ndlovu ukunikeza amathebhu onokwethenjelwa futhi elula.

Abenzi nangezibonakhulu

Quality futhi functional nangezibonakhulu akhiqizwa ngaphansi brand Bresser. In the line imikhiqizo ungathola imishini ukuthi unayo kokukhulisa 450-nesibaya, ifakwe amadivayisi obuchwepheshe kanye backlighting LED. Uma ufuna ukuhlomisa i-laboratory lonke isitshudeni, kufanele ukhethe i-ngesibonakhulu umfundi "Young Usosayensi" kusukela umakhi Ukutholwa. Idivayisi ine isakhiwo monocular-lens amancanyana enza nge ngezinga eliphezulu of ukukhushulwa 1200-nesibaya, okungase kubhekwe tintfo ngokuningiliziwe. Le modeli Ubuye isixha ezibanzi, okuhlanganisa izingxenye ezingu-60.

Kuvele ezithakazelisayo isixazululo misebenzi futhi inkampani Eastcolight. Abadali ukunikeza kits Amatebhe ukuthi abahlanganisi kwaphela microscope isitshudeni, kodwa futhi isibonakude. Kwandisa ikhono the kaningi sokuqala 900, lapho ikhithi okwengeziwe yakhiwa iqoqo ngezibuko nezingodo ze lens, amashiya, magnifiers, abanikazi, izinaliti futhi scalpels.

Izinsiza ze-microscope

Ngaphezu imishini eziyisisekelo, futhi kungadinga kumadivayisi angeziwe nemishini lula yesondlo zedivayisi, kanye nomsebenzi ucwaningo umsebenzisi abasha. Lokhu kungafaka kits micropreparations kanye nemikhiqizo ekunakekeleni yokukhanya. Kuhle futhi kuyancomeka umfundi ukuthola ngesibonakhulu kanye wezindlu womoya, izifutho akhethekile usula. Ukuze kube lula ukusetshenziswa futhi ngeke engadingekile ukunikeza ayizinkanyiso ahlukene, condensers nasizayo eyepiece lens.

isiphetho

Ngokusho izici ingane yayo amamodeli we nangezibonakhulu akuzona kude nozakwabo omdala ngokugcwele. Ngisho ikhwalithi yokukhanya namandla zithuthukisa ikhono layo ukuvimbela sikubiza amathuluzi ithoyizi. Noma kunjalo nangezibonakhulu kubafundi kusadingeka ezinye ukulinganiselwa ngokuya ukusebenza. Futhi kuyafaneleka, ngoba ukuqonda butholakala enqubweni eyinkimbinkimbi kokuma zamakhemikhali nezinto eziphilayo kungenzeka kuphela ngemva kokusebenza kumadivayisi entry level. Okwaziyo nje wena akufanele skimp lapho ekhetha isibonakhulu esikoleni - kungcono ukugxusha tech izindlela zesimanje Ergonomics. Nokho, lezi zimfanelo ezihlanganiswe onobuhle digital.
