怎樣使用顯微鏡

將(jiang)低(di)倍鏡轉至(zhi)鏡筒下方與(yu)鏡筒成(cheng)一直線。撥動反光(guang)(guang)鏡，調節至(zhi)視野最亮無陰影(ying)。反光(guang)(guang)鏡有平、凹(ao)兩(liang)面，光(guang)(guang)源強(qiang)時(shi)用平面，較暗(an)時(shi)用凹(ao)面，需要(yao)強(qiang)光(guang)(guang)時(shi)，將(jiang)聚光(guang)(guang)器提高，光(guang)(guang)圈(quan)放大；需要(yao)弱光(guang)(guang)時(shi)，將(jiang)聚光(guang)(guang)器降低(di)，或光(guang)(guang)圈(quan)適(shi)當縮小。

然后將(jiang)待觀察的標(biao)本(ben)置載物臺上(shang)，轉動粗(cu)調(diao)節(jie)(jie)(jie)器使鏡(jing)筒(tong)下降至(zhi)接(jie)物鏡(jing)接(jie)近標(biao)本(ben)。于(yu)轉動粗(cu)調(diao)節(jie)(jie)(jie)器的同時，須俯身在鏡(jing)旁(pang)仔細觀察接(jie)物鏡(jing)與標(biao)本(ben)之間的距離(li)。左眼于(yu)接(jie)目鏡(jing)觀察，同時左手轉動粗(cu)調(diao)節(jie)(jie)(jie)，使鏡(jing)筒(tong)徐徐上(shang)升以(yi)調(diao)節(jie)(jie)(jie)焦距，使視野內(nei)的物象看到上(shang)時即停，至(zhi)標(biao)本(ben)清晰(xi)為止。

顯微鏡的分類

根(gen)據(ju)顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)類型來分有(you)金相顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、體(ti)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(zi)顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、原子(zi)力(li)顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)等；從(cong)功(gong)能上分有(you)低倍顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、高倍顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、明(ming)揚顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、暗(an)揚顯(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(gan)涉顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)等；從(cong)光源來分有(you)同(tong)軸光顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、外(wai)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(hong)外(wai)顯(xian)(xian)(xian)(xian)微(wei)(wei)(wei)鏡(jing)(jing)(jing)、紫外(wai)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定要根據(ju)自(zi)己(ji)的需求(qiu)來(lai)選擇購買。
