研究了透明的和含有磷光体的重铬酸盐——聚乙烯醇(PVA)点的光致硬化与光波长的关系,利用荧光点直径对曝光时间的依赖性作为硬化程度的定量测量。 光源用—BH。型汞灯加一平行光管,汞灯具有连续光谱和一个跨200～500mμ的光化区域的汞线。光源用吸收滤光片滤光(NiSO_4吸收槽、康宁滤光片,系列为0、7、3),其狭窄程度足以分辨强和弱的重铬酸盐吸收带,但又宽到足以使用合理的曝光时间。 The relationship between the photohardenability and the light wavelength of transparent and phosphor-containing dichromate-polyvinyl alcohol (PVA) dots was investigated. The dependence of the phosphor dot diameter on the exposure time was used as a quantitative measure of the degree of hardening. -BH light source. Mercury lamp plus a parallel light pipe, mercury lamp with a continuous spectrum and a mercury line across the 200 ~ 500mμ actinic region. The light source is filtered by an absorption filter (NiSO 4 absorber, Corning filter, series 0, 7, 3) narrow enough to distinguish between strong and weak dichromate absorption bands but wide enough to be reasonably well used Exposure time.
