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.

Wavelength tunable narrow band filter

An anti-roll device including a gear fixed on a drive shaft and a gear fixed on a driven shaft, a pinion engaged on a rod, a number of gradually narrowing notches formed in the pinion, a roller and a spring disposed in each of the notches, the rollers being biased to move toward the narrower ends of the notches, the pinion being engaged with either of the gears, the rollers being caused to be wedged between the narrower ends of the notches and the rod when the pinion rotates in one direction, thereby locking the gear and the rod together, rotation of the pinion in an opposite direction is prevented.
