OPTICAL STACK, OPTICAL SYSTEM, OPTICAL DETECTION SYSTEM, AND OPTICAL IMAGING SYSTEM

An optical stack for sensing the presence of an analyte is provided. The optical stack includes a sensor material. The sensor material includes a first optical response responsive to an excitation signal, the first optical response including a first optical characteristic having a second value, the excitation signal including the first optical characteristic having a first value different from the second value. The first optical response includes a second optical characteristic that is sensitive to the presence of the analyte. The optical stack includes a first optical film disposed proximate to the sensor material and including a third optical characteristic having respective third and fourth values responsive to respective first and second values of the first optical characteristic. The third value differs from the fourth value by at least two times. 提供了一种用于感测分析物的存在的光学叠堆。该光学叠堆包括传感器材料。该传感器材料包括响应于激励信号的第一光学响应，该第一光学响应包括具有第二值的第一光学特性，该激励信号包括具有不同于该第二值的第一值的该第一光学特性。该第一光学响应包括对分析物的存在敏感的第二光学特性。该光学叠堆包括第一光学膜，该第一光学膜靠近传感器材
