怎樣使用顯微鏡

將(jiang)低倍鏡(jing)(jing)轉(zhuan)至(zhi)鏡(jing)(jing)筒下方與鏡(jing)(jing)筒成(cheng)一直(zhi)線(xian)。撥動(dong)反光(guang)鏡(jing)(jing)，調節至(zhi)視野最亮無(wu)陰(yin)影(ying)。反光(guang)鏡(jing)(jing)有平(ping)、凹兩面(mian)(mian)，光(guang)源強(qiang)時(shi)用(yong)平(ping)面(mian)(mian)，較(jiao)暗時(shi)用(yong)凹面(mian)(mian)，需要強(qiang)光(guang)時(shi)，將(jiang)聚光(guang)器提(ti)高，光(guang)圈放(fang)大；需要弱光(guang)時(shi)，將(jiang)聚光(guang)器降低，或(huo)光(guang)圈適當縮小。

然(ran)后(hou)將(jiang)待(dai)觀察的標(biao)(biao)本置(zhi)載物臺(tai)上(shang)，轉(zhuan)動(dong)(dong)粗調(diao)節(jie)器使(shi)鏡筒下降至接(jie)物鏡接(jie)近標(biao)(biao)本。于轉(zhuan)動(dong)(dong)粗調(diao)節(jie)器的同時(shi)，須俯(fu)身在鏡旁仔細觀察接(jie)物鏡與標(biao)(biao)本之間的距離。左(zuo)眼于接(jie)目鏡觀察，同時(shi)左(zuo)手轉(zhuan)動(dong)(dong)粗調(diao)節(jie)，使(shi)鏡筒徐徐上(shang)升以調(diao)節(jie)焦距，使(shi)視(shi)野(ye)內的物象看到上(shang)時(shi)即停，至標(biao)(biao)本清晰為止(zhi)。

顯微鏡的分類

根據顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)類型來(lai)(lai)分(fen)有(you)金相顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、體視(shi)顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、視(shi)頻顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、測(ce)量顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、掃(sao)描(miao)電子(zi)顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、原(yuan)子(zi)力顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)等；從功能上分(fen)有(you)低倍顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、高倍顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、明揚顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、暗(an)揚顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、偏光(guang)(guang)顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、微(wei)(wei)(wei)(wei)(wei)(wei)分(fen)干涉顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)等；從光(guang)(guang)源來(lai)(lai)分(fen)有(you)同軸光(guang)(guang)顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、外罝(ju)光(guang)(guang)顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、光(guang)(guang)顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、紅外顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(wei)(wei)(wei)鏡(jing)(jing)(jing)、紫外顯(xian)(xian)(xian)(xian)(xian)微(wei)(wei)(wei)(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。大家在(zai)購(gou)買(mai)顯微鏡的時(shi)候一定要根據自己的需(xu)求來選(xuan)擇(ze)購(gou)買(mai)。
