An apparatus includes a planar member having a first planar surface, a hollow body having first and second end openings, and a window. The planar member is configured to receive a device mounted on the first planar surface and surrounded by at least a track of a first material having a first hardness affixed to the first planar surface. The hollow body has a sharp edge at the second end along a planar section of the hollow body. The hollow body comprises a second material with a second hardness equal to or greater than the first hardness. The window encloses the hollow body first end forming an enclosure interior region configured to surround the device. The window provides the transmission of light into or out of the interior region. The hollow body second end is urged against the first material to form a hermetically sealed enclosure around the device.
