怎樣使用顯微鏡

將低倍鏡(jing)轉至鏡(jing)筒下(xia)方(fang)與鏡(jing)筒成一直(zhi)線。撥動反光(guang)鏡(jing)，調(diao)節至視野最亮無陰影。反光(guang)鏡(jing)有平、凹兩面，光(guang)源強時(shi)用(yong)平面，較暗時(shi)用(yong)凹面，需要強光(guang)時(shi)，將聚光(guang)器提高，光(guang)圈放大；需要弱光(guang)時(shi)，將聚光(guang)器降低，或(huo)光(guang)圈適當(dang)縮小。

然后將待觀察的(de)標(biao)(biao)本(ben)(ben)置載(zai)物(wu)臺上(shang)(shang)，轉動(dong)粗調節器(qi)使(shi)鏡(jing)筒下降至(zhi)接物(wu)鏡(jing)接近標(biao)(biao)本(ben)(ben)。于轉動(dong)粗調節器(qi)的(de)同時(shi)，須俯身在鏡(jing)旁仔細觀察接物(wu)鏡(jing)與標(biao)(biao)本(ben)(ben)之間的(de)距離。左眼于接目鏡(jing)觀察，同時(shi)左手轉動(dong)粗調節，使(shi)鏡(jing)筒徐(xu)徐(xu)上(shang)(shang)升以調節焦距，使(shi)視野內(nei)的(de)物(wu)象(xiang)看到上(shang)(shang)時(shi)即停，至(zhi)標(biao)(biao)本(ben)(ben)清晰為止。

顯微鏡的分類

根據顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)類(lei)型來分有金相(xiang)顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、體視顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、視頻顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、測量顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、掃(sao)描電子顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、原子力顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)等；從(cong)功(gong)能上分有低倍(bei)顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、高倍(bei)顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、明揚(yang)顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、暗揚(yang)顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、偏光顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、微(wei)(wei)(wei)分干涉顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)等；從(cong)光源來分有同軸(zhou)光顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、外罝光顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、光顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、紅外顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、紫外顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)等。

顯微鏡多少錢一臺

一臺顯微鏡根據用途不一樣，功能不一樣，配罝不一樣、顯微鏡品牌不同等這些因素價格都會不一樣，像一般學校教學實驗室用的話大概三四千的樣子，而專業的高端實驗用的話，一般要萬元甚至數萬元左右。大家(jia)在購買顯微鏡的時候一(yi)定要根據自(zi)己的需求來選擇購買。
