干涉滤光片特性及使用方式对光电高温计有效波长的影响研究
Study on Effect of Interference Filter Characteristics and Using Mode on Effective Wavelength of Photoelectric Pyrometers
摘要
Abstract
Based on the spectral responsivity test system and interference filter transmittance test system of the supercontinuum laser,the effects of filter characteristics and use methods on the effective wavelength of the pyrometer at the center wavelength of 660 nm are analyzed from four aspects,including filter selection and angle of incidence,internal reflection and measurement repeatability.The test finds that poor cut-off characteristics of filters and their use methods will directly affect the results of effective wavelength of pyrometer.It is found that filters with poor cutoff characteristics may lead to a temperature measurement error of 0.5℃,non-parallel light-incidence mounted filters will have the risk of light leakage in the cut-off wavelength of 950～110 0 nm,which may affect the temperature measurement by more than 1℃,and the reflected light inside the pyrometer is not effectively shielded,which also leads to the generation of spectral response that should not be present in the cut-off wavelength of 700～1 100 nm,which may even affect the temperature measurement by more than 10℃.The experimental results show that the measurement repeatability of the new responsivity test system is good,and the uncertainty of the evaluated effective wavelength division is 0.066 nm(k=2),the uncertainty affecting the photoelectric pyrometer temperature measurement of 2 700 ℃ does not exceed 0.3 ℃.关键词
