Valime mikroskoopi<\/strong>.<\/strong><\/span><\/h3>\n

\u00dcks hea kodune mikroskoop peab v\u00e4lja n\u00e4gema nii:\u00a0 <\/strong><\/span><\/p>\n

\u2013 metallkorpus<\/p>\n

\u2013 klaasist, mitte aga plastist optika<\/p>\n

\u2013 valgusdiood v\u00f5i halogeenvalgustus (\u00fclemine lisavalgustus avardab teie v\u00f5imalusi)<\/p>\n

\u2013 3 v\u00f5i 4 objektiiviga revolverseade<\/p>\n

\u2013 lastele, kooli\u00f5pilastele ja harrastajatele sobib mikroskoop 100 kuni 200- kordse suurendusega.<\/p>\n

\u2013 m\u00f5ningaid mudeleid m\u00fc\u00fcakse kandekotiga. Sellist mikroskoopi on mugav v\u00f5tta reisile v\u00f5i matkale!<\/p>\n

Kasulikud soovitused<\/strong><\/span>:<\/span>
\n<\/strong>\u00c4rge unustage mikropreparaatide komplekte \u2013 uuringun\u00e4idiseid. Nendeks v\u00f5ivad olla taimede \u00f5hukesed l\u00f5ikekohad, vees olevad heljumid, mikroorganismid ja palju muud. Iseseisvalt, katsetamata, on neid keeruline teha.<\/p>\n

Kui tahate koheselt pildi \u00fcle kanda arvutile v\u00f5i salvestada video, v\u00f5iks valida digitaalse usb-mikroskoobi. Digimikroskoobile v\u00f5ib heaks alternatiiviks saada mobiiltelefoni salvestatud sisseehitatud statiiviga optiline mikroskoop, mis samuti lubab avaldada internetis oma vaatluseid.<\/p>\n

Tasub m\u00e4rkida, et \u00fches ja samas hinnasegmendis olevad optilised seadmed annavad p\u00f5hjalikuma pildi v\u00f5rreldes digiseadmetega.<\/p>\n

Igas veetilgas v\u00f5ib mikroskoobi abil n\u00e4ha imetillukeste organismidega, zooplanktoniga tervet maailma. Puuviljade ja k\u00f6\u00f6giviljade viljaliha osakestes aga avaneb taimeraku t\u00f5eline ilu \u2013 sibulal on need niiv\u00f5rd suured, et n\u00e4idises v\u00f5ib n\u00e4ha tuuma, rakuseina ja isegi kloroplaste. Veel aga on v\u00e4ga tavatu\u00a0 hallitus \u2013 leivat\u00fckil \u00f5nnestub n\u00e4ha seente tippusid (niiditaoline moodustis) ja eoseid.<\/p>\n

Edu Teile<\/strong>!<\/strong><\/span><\/h3>\n

Allpool vaatleme p\u00f5hjalikult mikroskoobi p\u00f5hiparameetreid ja konstruktsiooni.<\/p>\n

\"\"Mitu okulaari on parem: \u00fcks, kaks v\u00f5i isegi kolm?<\/span><\/strong><\/p>\n

Mikroskoobi valikul m\u00e4ngib okulaar v\u00e4gagi t\u00e4htsat rolli, kuna just sellest s\u00f5ltub paljuski seadme kasutusmugavus. Eksisteerib mitu varianti:<\/p>\n

    \n
  • \n
      \n
    • Monokulaarsed \u2013 eeldavad n\u00e4idise vaatlust \u00fche silmaga. Hea lahendus l\u00fchivaatluste korral ja asjaarmastajatele kasutamiseks.<\/li>\n
    • Binokulaarsed \u2013 mugavam. Seda t\u00fc\u00fcpi mikroskoopi tasuks valida juhul, kui kavatsete n\u00e4idiste uuringute taga veeta\u00a0 \u00fcsna palju aega.<\/li>\n
    • Trinokulaarne \u2013 kolmas okulaar on m\u00f5eldud kaamera l\u00fclitamiseks ja kujutise v\u00e4ljutamiseks suuremale ekraanile. Selline mikroskoop sobib r\u00fchmatundideks v\u00f5i pildi salvestamiseks.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

      Samuti v\u00f5ib seadmel okulaari asemel olla v\u00e4iksem ekraan.<\/p>\n

      \"\"<\/p>\n

      Valgustuse erimid<\/strong><\/span><\/p>\n

      Vastates k\u00fcsimusele selle kohta, kuidas valida mikroskoopi, tuleb mainida valgusallika erinevust. Sellest s\u00f5ltub saadud kujutise kvaliteet. Lihtsamates mudelites kasutatakse peegleid ja loomulikku valgustust. Millist mikroskoopi aga valida, kui tahaks vaatluseid teha s\u00f5ltumata ilmast ja \u00f6\u00f6p\u00e4eva ajast? T\u00e4iendava valgustusega kindlasti! See v\u00f5ib olla mitut t\u00fc\u00fcpi:<\/p>\n

        \n
      • \n
          \n
        • h\u00f5\u00f5glamp \u2013 \u00fcks lihtsaim lahendus, kuid soojuskiirgus v\u00f5ib n\u00e4idised \u00fclekuivatada, tappa uuritavad mikroorganismid;<\/li>\n
        • valgusdioodid \u2013 universaalne lahendus minimaalse soojenemise ja ereduse reguleerimisega;<\/li>\n
        • halogeenlambid \u2013 annavad v\u00e4ga v\u00f5imsa valgusvoolu, mist\u00f5ttu paigaldatakse neid vaid professionaalsetesse mudelitesse.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

          Millist fokusseerimist\u00fc\u00fcpi eelistada?<\/strong><\/span><\/p>\n

          J\u00f5uda selgusele k\u00fcsimuses, millist mikroskoopi oleks m\u00f5ttekam osta, ei ole fokusseerimist\u00fc\u00fcbi m\u00e4\u00e4ratluseta v\u00f5imalik. See on l\u00e4\u00e4tse \u201csuunamise\u201d viis objektile. Lihtsamatel mudelitel on vaid j\u00e4me fokusseering, mille korral moodustab l\u00e4henemise\/kaugenemise samm 0,2-2 mm. Sellest piisab, kui kasutatakse kuni 400 kordset suurendamist.<\/p>\n

          Kui teid huvitab, millise mikroskoobi peaks valima p\u00f5hjalikemaks vaatlusteks, tasuks kaaluda peenfokusseerimise t\u00e4iendava k\u00e4epidemega varianti. See suudab tagada 1-20 mikroniga sammu.<\/p>\n

          Suurendamine: kasulik ja kasutu\u00a0<\/span><\/strong><\/p>\n

          K\u00fcsimusele, milline on k\u00f5ige parem mikroskoop, v\u00f5ivad paljud ostjad vastata, et see, mis suurendab k\u00f5ige enam. Kuid see on eksiarvamus. V\u00e4hev\u00f5imsad objektiivid ja okulaarid on igal juhul vajalikud, kuna nendeta ei ole v\u00f5imalik n\u00e4ha n\u00e4idise \u00fcldpilti. T\u00e4helepanu tuleb p\u00f6\u00f6rata vaid kasuliku suurendamise n\u00e4itajale, mis on nominaalsest palju madalam (saaduna objektiivi ja okulaari n\u00e4itajate \u00fcmberkorrutamise teel).<\/p>\n

          \u201eKasutu\u201c suurendamine vaid l\u00e4hendab pilti, lisamata sellele detaile. Mist\u00f5ttu k\u00fcsimuses, kuidas valida mikroskoopi, ei tohiks jahtida \u00e4\u00e4rmiselt suuri numbreid, mida amat\u00f6\u00f6rkasutuses kindlapeale ei vajata.<\/p>\n
