Abstract:

A device. At least some example embodiments are a device including a filter element configured to receive optical energy from a first optical fiber. The filter element is reflective in a preselected band of optical wavelengths. A first lens is configured to receive optical energy transmitted through the filter element. A shell is disposed about the optical filter and the first lens; surfaces of the first lens, the filter element and the shell form a first boundary portion of an internal volume of an interior of the shell. A fluid is sealably disposed within the internal volume.
