Ka wehewehe ʻana o ka microscope
He microscope kahi mea hana maka hoʻohana ʻia e kōkua i ka maka e ʻike i nā mea liʻiliʻi, kahi e paʻakikī ai ke nānā pololei i nā mea liʻiliʻi me ka hoʻohana ʻana i nā maka a i ʻole ka loupe.
ʻElua ʻano microscopes, ʻo ia hoʻi ka microscope māmā a me ka microscope electron. Kūkākūkā kēia haʻawina i ka microscope māmā, a ʻo ke ʻano o kāna hana e pili ana i ke kumuhana o ka geometry optics e pili ana i ka refraction o ka mālamalama, ka hoʻokumu ʻia ʻana o nā kiʻi a me ka hoʻonui ʻana i nā kiʻi o kahi mea me ka hoʻohana ʻana i kahi lens.
Pehea e hana ai ka microscope
ʻO kahi microscope māmā he ʻelua mau aniani convex. ʻO ka aniani convex nona ka mamao kokoke i ka mea i nānā ʻia ua kapa ʻia ʻo ka aniani objective. ʻO ka aniani convex e kokoke ana i ka maka o ka mea nānā, ua kapa ʻia ʻo ka aniani ocular a i ʻole ka aniani maka.
He liʻiliʻi ka mea, no laila, ʻoiai ke nānā ʻia nei lākou mai kahi kokoke, he 25 kenimika ke kaʻawale, he liʻiliʻi ke kihi i hana ʻia ma waena o ka maka a me ka mea. No laila, hana ka lens objective e hoʻonui i ke kiʻi o ka mea a hoʻonui i ke kihi ma waena o ka maka a me ke kiʻi o ka mea. Pono nā kiʻi i hana ʻia e nā lens objective e maoli i ʻike ʻia ma o ka lens ocular. I mea e maoli ai ke kiʻi i hana ʻia e kahi lens convex, pono e ʻoi aku ka mamao o ka mea (do) ma mua o ka lōʻihi o ke kikowaena. Pēlā nō, i ʻoi aku ka nui o ke kiʻi ma mua o ka mea, pono e kokoke ka mamao o ka mea i ke kikowaena o ka lens objective.
ʻO ke kiʻi i hana ʻia e ka lens objective he mea maoli ia i hiki ai ke manaʻo ʻia ke kiʻi he mea e ka lens ocular. ʻO ka hana o ka lens ocular ka hoʻonui ʻana i ke kiʻi maoli i hana ʻia e ka lens objective i mea e ʻoi aku ka nui. He lens convex ka lens ocular no ka mea e like me ka mea i wehewehe ʻia ma ke kumuhana o ka lens convex, i mea e nui a kū pololei ai ke kiʻi i hana ʻia e ka lens ocular, pono ke kiʻi virtual.
Hoʻonui piha ʻia o ka microscope
ʻOi aku ka nui o ke kiʻi o nā mea i ʻike ʻia ma o kahi microscope ke nānā ʻia e nā maka me ka liʻiliʻi o ka noho ʻana a i ʻole ka nui o ka noho ʻana? ʻO wai ka mea e hoʻohana ʻia ma ke ʻano he lens objective a me ocular, kahi lens convex me ka lōʻihi focal nui a i ʻole kahi lens convex me ka lōʻihi focal liʻiliʻi? Hiki ke pane ʻia kēia mau nīnau ma hope o kou aʻo ʻana i ka hoohalike o ka microscope.
