ABSTRACT:
The invention provides a sensor including a first sensor element formed in a first substrate and at least one optical element formed in a second substrate, the first and second substrates being configured relative to one another such that the second substrate forms a cap over the first sensor element. The cap includes a diffractive optical element and an aperture stop which collectively determine the wavelength of incident radiation that is allowed through the cap and onto the at least one optical element.
