摘　　要：目的:探讨了多波段光源在现场唾液斑发现中的应用价值。方法:在实验室条件下,运用LUMATEC SUPERLITE(S400)多波段光源各多波段对不同载体、不同个体和不同离体时间的唾液斑进行观察,探讨不同载体、不同个体和不同离体时间的唾液斑的最佳发现波长。结果:LUMATEC SUPERLITE(S400)多波段光源440nm和415nm均能较好发现各种现场遗留的唾液斑。结论:LUMATEC SUPERLITE(S400)多波段光源光源在唾液斑的发现中具有重要作用,室内现场勘查中利用多波段光源的440nm波长,配以黄色滤镜为较好的搜寻唾液斑的方法。The objective is to explore the application v alue of multiband light source in detecting saliva stain. The method is to observe different carriers, different individuals and of saliva stain in different times with LUMATEC SUPERLITE（S400） multiband light source in laboratory to explore the best wave length. The result is that LUMATEC SUPERLITE（S400） multiband light sources at 440 nm and 415 nm were able to detect various saliva stain left over from the site. The conclusion is that LUMATEC SUPERLITE（S400） multiband light source plays an important role in finding the saliva stain, multichannel wavelength of 440 nm light source with yellow filter is a good method of finding saliva stain in indoor crime scene investigation.
