一、Leica DM2500 M金相顯微鏡(德國徠卡全手動(dòng)正置型)主要特點(diǎn)
1、可選配帶角度調(diào)節(jié)的目鏡筒,大大降低操作者的疲勞。
2、目鏡視野直徑22mm。
3、物鏡直徑32mm,使光通量提高了40%,擁有更高的分辨率和景深。
4、物鏡轉(zhuǎn)換手動(dòng)控制。
5、可升級選配變倍器,有1.5X、1.6X、2X三種可選。
6、明場、暗場、偏光、干涉觀察方式手動(dòng)轉(zhuǎn)換。
7、孔徑光闌檔位與物鏡倍數(shù)對應(yīng),以不同顏色精確標(biāo)記,更快速恢復(fù)工作狀態(tài), 視場光闌檔位與目鏡的視野數(shù)對應(yīng),另有暗場檔位,相機(jī)靶面尺寸檔位。
8、機(jī)身采用反向溫度補(bǔ)償技術(shù),有效降低了因發(fā)熱造成的焦平面漂移。
9、具有4位濾色鏡架插槽,可以同時(shí)插入四種不同色的濾色鏡在待插入位置,既隨時(shí)推入拉出,有可防灰塵進(jìn)入光路。
10、具有聚焦高度限位裝置,防止樣品碰到物鏡。
11、可選配徠卡原裝顯微鏡數(shù)碼成像裝置,實(shí)現(xiàn)全部的本廠配置,達(dá)到整體和諧。
12、可選配徠卡各種圖像處理及分析軟件,包括景深擴(kuò)展軟件,通用圖像分析軟件,金相分析軟件。
13、可接干涉臺(tái)階儀進(jìn)行高精度測量;
14、可接大尺寸物臺(tái)用于半導(dǎo)體檢測;
15、可升級為其他觀察方法。
二、徠卡(德國徠卡全手動(dòng)正置型)技術(shù)參數(shù):
1、目鏡:10X、視域直徑25mm
2、目鏡筒:可55-75mm瞳間距調(diào)節(jié)

4、手動(dòng)載物臺(tái):移動(dòng)行程76X50mm,可110度旋轉(zhuǎn),載重4Kg,可適應(yīng)高樣品高度40mm
5、手動(dòng)調(diào)焦:升降范圍=50mm,具有粗中細(xì)三檔調(diào)焦步進(jìn)精度,細(xì)調(diào)焦精度1um
6、目視放大倍數(shù):50X--1000X(可根據(jù)需要擴(kuò)展此范圍)
7、物鏡位數(shù):金相物鏡5位,普通物鏡可6位
