摘要：
A narrow bandpass filter that may be used in a mid-infrared sensor for monitoring a species, which may be a component of a fluid or a solid material. The filter comprises a cavity comprising a low refractive index material. By providing a high ratio of low refractive index material in the filter with respective to high refractive index material, the filter is configured so that wavelength transmission remains constant with varying temperature. Materials used for the low and/or high refractive index provide a temperature invariant filter that transmits mid-infrared spectra without serious degradation.
摘要（中）：
可用于中红外传感器的窄带通滤波器，用于监测物种，其可以是流体或固体材料的组分。 该滤光器包括一个包含低折射率材料的空腔。 通过在滤光器中提供高折射率材料与高折射率材料的高比率，滤光器被配置为使得波长透射在温度变化时保持恒定。 用于低和/或高折射率的材料提供了传递中红外光谱而不严重退化的温度不变滤波器。
