一、问题的提出 显微投影仪是用于切片放大、投影的观察仪器。它是由光源、宽带反射镜、显微镜和屏幕所组成。其光路原理图如图1所示。 1.光源 2.红外滤色镜 3.宽带反射膜 4.紫外滤色镜 5.聚光镜 6.显微镜 7.反射镜 8.屏幕 9.样品 图1 显微投影仪光路图 医学(生物)切片由强光照射,通过显微镜的放大,在屏幕上得到清晰的投影像,供会诊,示教之用。投影像要求色彩鲜艳图像不失真,细微结构清晰可辨。
First, the issue put forward Microscopic projector is used for slicing magnification, projection observation instrument. It consists of a light source, a broadband mirror, a microscope and a screen.

Sample Figure 1 Micro-projector optical pathology Medical (biological) sections illuminated by bright light, Through the magnification of the microscope, a clear projection image is obtained on the screen for consultation and teaching purposes. Projection like color image requires distortion, fine structure is clearly identifiable.
