显微投影仪也叫投影光源,它是按照教育部普教仪器目录中的投影光源设计的.在设计时着重提高了放映镜头的结构和鉴别率,使其既能作投影光源又能直接投影切片.它的主要用途有二:一是作高倍显微镜投影光源用.它的出口照度达250000——300000勒克斯,对非常难观察的切片(需放大500——1500倍时),用此光源和高倍显微镜配合,投影到毛玻璃上能得到非常清晰的效果,可供多数学生同时观察.二是对一般生物切片(放大倍数在200倍左右时),不用
Micro-projector is also called projection light source, which is designed according to the projection light source in the catalog of general education equipment of the Ministry of Education.It focuses on improving the structure and discrimination rate of the projection lens at the time of design, making it both for projection light source and direct projection It has two main purposes: First, for high-power microscope projection light source. Its export illumination of 250000 - 300000 lux, for the very difficult to observe the slice (to be enlarged 500--1500 times), with this light source and High magnification microscope, projected onto the ground glass can get very clear effect, for most students at the same time observe the second is the general biopsy (magnification at about 200 times), do not have
