SBIR Phase I: Tandem Ebert-Fastie Double Monochromator and Calibration Transfer Spectroradiometer for Ultra-Violet (UV) Surface Radiation Monitoring

这个小型企业创新研究（SBIR）一期项目将对125毫米焦距、串联Ebert-Fastie双单色仪和校准传递光谱仪进行表征和评估，该光谱仪使用超稳定的硝化硅光电二极管和超稳定的窄带、“硬化”（对高温、湿度和老化影响的环境应力不敏感）离子辅助沉积过滤器。这种双单色仪是下一代，中等成本，紫外线（UV）表面辐射监测仪器。第一阶段还将确定一些当前余弦受体的透光稳定性。这种双单色仪和校准转移标准光谱辐射计具有潜在的用途，作为现场紫外线表面辐射和臭氧监测仪器，以及在实验室和工业中，它可以建立一个通用的辐射尺度，用于光谱辐射和辐照度校准，并提供精确的实验室光谱辐射测量。＊＊＊

*** 96-60722 Heath This Small Business Innovation Research (SBIR) Phase I project will characterize and evaluate a 125-millimeter focal length, tandem Ebert-Fastie double monochromator in combination with a calibration transfer spectrometer which uses ultrastable nitrated silicon photodiodes in combination with ultra stable narrow-band, "hardened" (insensitive to environmental stresses of high temperature, humidity, and aging effects), ion-assisted deposition filters. This double monochromator is a next-generation, moderate cost, ultraviolet (UV) surface radiation-monitoring instrument. Phase I will also determine the transmittance stability of some current cosine receptors. This double monochromator and calibration transfer standard spectroradiometer have potential uses as a field UV surface radiation and ozone monitoring instrument, as well as in the laboratory and industry where it can establish a common radiometric scale for spectral radiance and irradiance calibrations and provide precision laboratory spectroradiometric measurements. ***
