Various embodiments of the present application are directed towards an image sensor including a wavelength tunable narrow band filter, as well as methods for forming the image sensor. In some embodiments, the image sensor includes a substrate, a first photodetector, a second photodetector, and a filter. The first and second photodetectors neighbor in the substrate. The filter overlies the first and second photodetectors and includes a first distributed Bragg reflector (DBR), a second DBR, and a first interlayer between the first and second DBRs. A thickness of the first interlayer has a first thickness value overlying the first photodetector and a second thickness value overlying the second photodetector. In some embodiments, the filter is limited to a single interlayer. In other embodiments the filter further includes a second interlayer defining columnar structures embedded in the first interlayer and having a different refractive index than the first interlayer.

The invention relates first to a camera module for a microscope. The camera module comprises an optical interface for inserting the camera module into an imaging beam path of the microscope, which imaging beam path images a nominal intermediate image. Furthermore, the camera module comprises an electronic image converter and a functional element for changing an intermediate image plane, which functional element is arranged in a beam path of the camera module between the optical interface and the image converter. The camera module also comprises a first optical assembly having an optical power, which first optical assembly is arranged in the beam path between the optical interface and the image converter. According to the invention, a distance between the functional element and the optical interface along the beam path or a distance between the first optical assembly and the optical interface along the beam path can be changed. The invention further relates to a method for operating the camera module.
