    • The invention relates to the combination of lower transmittance etalons with higher transmittance filters, including use of a single circular polarizer with high efficiency and optical performance for its filtered polarization, to achieve necessary throughput of a narrow bandpass region. The lower transmittance etalons can be achieved by using lower transmittance solid-state etalon materials, or by control of the coatings on the etalon. Alternate configurations are described that reduce the optical assembly's footprint, and/or include additional filters to remove stray light. An innovative option to heat the etalon directly is disclosed to actively stabilize and maintain the etalon's bandpass.
    • 本发明涉及低透射率标准具与较高透光率滤光片的组合,包括使用具有高效率的单一圆偏振器和其滤光极化的光学性能,以实现窄带通区域的必要吞吐量。 较低的透光率标准具可以通过使用较低透光率的固态标准具材料或通过控制标准具上的涂层来实现。 描述了减少光学组件的占地面积的替代配置,和/或包括用于去除杂散光的附加过滤器。 披露了直接加热标准机的创新选择,以积极稳定和维护标准具的带通。
