怎樣使用顯微鏡

將(jiang)低(di)倍鏡(jing)轉至鏡(jing)筒下方與鏡(jing)筒成一直線。撥動(dong)反(fan)光(guang)(guang)鏡(jing)，調(diao)節至視野最亮無陰影(ying)。反(fan)光(guang)(guang)鏡(jing)有平、凹兩(liang)面，光(guang)(guang)源強時(shi)(shi)(shi)用平面，較暗時(shi)(shi)(shi)用凹面，需要強光(guang)(guang)時(shi)(shi)(shi)，將(jiang)聚光(guang)(guang)器提高，光(guang)(guang)圈放大；需要弱光(guang)(guang)時(shi)(shi)(shi)，將(jiang)聚光(guang)(guang)器降低(di)，或光(guang)(guang)圈適當縮小。

然后將待觀察的(de)標本(ben)(ben)置載物(wu)臺上(shang)(shang)，轉動粗(cu)(cu)調(diao)節(jie)器使(shi)(shi)鏡(jing)筒下降(jiang)至接物(wu)鏡(jing)接近(jin)標本(ben)(ben)。于(yu)(yu)轉動粗(cu)(cu)調(diao)節(jie)器的(de)同時，須(xu)俯身在鏡(jing)旁仔細觀察接物(wu)鏡(jing)與標本(ben)(ben)之間的(de)距(ju)離。左眼于(yu)(yu)接目鏡(jing)觀察，同時左手轉動粗(cu)(cu)調(diao)節(jie)，使(shi)(shi)鏡(jing)筒徐徐上(shang)(shang)升以調(diao)節(jie)焦(jiao)距(ju)，使(shi)(shi)視野內的(de)物(wu)象看到上(shang)(shang)時即停(ting)，至標本(ben)(ben)清晰(xi)為止(zhi)。

顯微鏡的分類

根據顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)類型來分(fen)有(you)金相顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、體視(shi)顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、視(shi)頻顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、測量顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、掃(sao)描電(dian)子顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、原子力(li)顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)等；從功能上分(fen)有(you)低(di)倍顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、高倍顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、明揚(yang)顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、暗揚(yang)顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、偏光(guang)顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、微(wei)(wei)(wei)(wei)分(fen)干涉顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)等；從光(guang)源來分(fen)有(you)同軸光(guang)顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、外罝光(guang)顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、光(guang)顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、紅外顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(jing)(jing)、紫外顯(xian)(xian)(xian)微(wei)(wei)(wei)(wei)鏡(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(da)家在購買(mai)顯(xian)微(wei)鏡的(de)時候一定要根據自己(ji)的(de)需(xu)求來選擇購買(mai)。
