69X系列偏光顯微鏡用途概述：
采用透射照明系統(tǒng)，主要用于對(duì)各種透明的晶體、巖石、礦物以及具有雙折射的物質(zhì)進(jìn)行觀察和鑒定，是地質(zhì)、礦產(chǎn)、冶金等部門(mén)和相關(guān)高等院校zui為常用的專(zhuān)業(yè)實(shí)驗(yàn)儀器之一。也可用于紡織、化纖行業(yè)對(duì)紡織纖維和科研單位對(duì)藥物進(jìn)行檢驗(yàn)。隨著光學(xué)技術(shù)的不斷進(jìn)步，偏光顯微鏡其應(yīng)用也越來(lái)越廣泛，可供用戶作單偏光觀察;正交偏光觀察;錐光觀察以及顯微攝影，配置有石膏λ、云母1/4λ試片、石英楔子和移動(dòng)尺等附件，是有一組具有較完備功能和良好品質(zhì)的產(chǎn)品。
The 69X polarizing microscope uses the transmission illumination system, mainly uses in to each kind of transparent crystal, the rock,the ore as well as has the double refraction the matter to carry on the observation and the appraisal, This one of in common use specialty experiment instruments correlation, geology, minerals, metallurgy department and college etc. Also may use in the textile, the chemical hemp industry carries out the examination to the textile hemp and the medical unit to the medicine. Along with the optics technology unceasing progress, polarizing microscope its application more and more is also widespread, may make the single polarized light observation for the user; Orthogonal polarized light observation; The awl light observation as well as the micrograph, the disposition have the gypsumλ，the mica 1/4λpreviews, appendix and so on quartz wedge and motion ruler, has a group to have the maturity function and the good quality product.
