    Abstract: A color detector includes a light source, a photodiode, and a filter tuned to only allow light of a specific color to pass through to the photodiode. When the light reaches the photodiode, the photodiode outputs a current that indicates that the color is present in the light. The filter may include a pair of partially reflective layers consisting of a reflective metal, such as silver. To prevent the metal from oxidizing or reacting with the environment, the partially reflective layers may be coated with a protective layer, such as aluminum nitride. The color detector may further include a color enhancing layer. Finally, the color detector may include a capping layer. Accordingly, the color detector provided herein allows for the filter to use metals for partially reflective layers that would normally oxidize, as well as detect light of a specific spectrum of wavelengths.

    Abstract: A color detector includes a light source, a first filter, and a first photodetector. The light source generates light within a spectrum of wavelengths. The first filter is in optical communication with the light source and is configured to pass light within a first predetermined spectrum of wavelengths. The first photodetector is in optical communication with the first filter and is configured to output a first color signal if light passes through the first filter. The photodetector has an area configured to equalize the first color signal and maximize a signal-to-noise ratio of the first color signal.

    Abstract: An optical device includes an aperture stop that limits an angular extent of light from an illuminated sample. A first lens is positioned between the aperture stop and a detector plane. A second lens is positioned between the first lens and the detector plane and is operable to map light from the aperture stop to the detector plane such that the light is averaged at the detector plane.

    Abstract: A light source arrangement has a first light source, a second light source and a dichroic mirror. The dichroic mirror is disposed with the first and second light sources and configured to reflect a predetermined portion of the light emitted from the first light source and to transmit the remaining portion. The dichroic mirror is also configured to reflect light emitted from the second light source so that it propagates in the same direction as the remaining portion of the light from the first light source which is transmitted through the dichroic mirror.
