摘要: 本文利用直流空心阴极放电方式产生了一种新型氮气等离子体蓝紫光源,实现了针对传统的预涂感光版(PS版)的感光,当N2气压70 Pa、放电电压580 V、电流1.8 A时,产生的蓝紫光功率密度为0.46 mW/cm2.本文进一步从曝光前后颜色密度值变化、感光材料红外分析方面,对PS版的曝光效果做了详细的测量.

Abstract: In this paper,the possible PS exposure source based on a novel N2 plasma generated in direct current hollow cathode discharge(HCD) is investigated.With the applied voltage 580 V,current 1.8 A and working pressure 70 Pa an optical power density of 0.46 mW/cm2 is obtained,in which the conventional PS plate can be well photosensitized.As a result the efficiency of photosensitivity this source is discussed in detail from the color density change and the FTIR analysis on the coating material.

Key words: hollow cathode discharge (HCD), PS plate, high frequency pulse plasma
