Brief

The article discusses the performance optimization of a bandpass filter through process improvements, as evidenced by changes in its spectral characteristics.

Summary

This article discusses bandpass filters, presenting performance metrics and improvements before and after optimization [1, Table 1]. It mentions the use of double half-wave high-contrast narrowband filters for target detection and imaging [1, Summary], and describes bandpass filters designed for visible and near-infrared light at various incident angles, emphasizing substrate selection and film design [1, Section on 带通滤光片]. The article also briefly introduces an infrared camera system, an example of a technology that might utilize such filters for specific spectral applications [1, Section on 红外摄像机组件].
