应中国医学科学院卫生研究所的要求,我校应用物理系激光技术教研室为该所研制标准粒子发生器打出直径为3微米以下的小孔。孔径和孔形见下面扫描电子显微镜放大图片。 目前该教研室可在不同的金属片上打出3微米以下至200微米各种直径的小孔。这些小孔目前作为光学空间滤波器、电视像管第一阳极、通光孔等,已供应国内有单位使用。 At the request of the Institute of Hygiene, Chinese Academy of Medical Sciences, the Department of Applied Physics Department of Laser Technology instructed the Institute to develop a standard particle generator with a diameter of 3 microns or less. See aperture and aperture below scanning electron microscope to enlarge the picture. At present, the teaching and research room can punch holes of various diameters up to 200 microns in diameter on different metal sheets. These holes are currently used as optical space filters, television tube first anode, through holes, etc., have been supplied to domestic units.
