A protective foam layer is provided. The protective layer has a foam substrate that is at least partially enclosed by a formed skin adjacent the outer surface of the foam substrate. The formed skin is substantially non-porous. The combination of the foam substrate with the formed skin results in a protective layer that is effective to absorb and/or dissipate impact force for both high- and low-speed impacts that can be experienced during a sporting event such as cycling. The formed skin can also be provided with a plurality of protective zones having vent holes through the formed skin to regulate the degree of energy absorption in the respective zones. In this manner, a single continuous protective foam layer can be provided having multiple protective zones having distinct energy absorption characteristics instead of providing discrete protective layers that must be joined or meet at a seam. According to the invention, by providing such a continuous protective layer with no such seams, a known failure mode in protective equipment is eliminated.

An FT-IR spectrometer (10) operated for analysis by reflectance spectroscopy, has a window (56) having a body (58) which generally transmits radiation in the visible range there through. The window has a surface (60) for supporting a sample (72) of material to be analyzed. The surface of the window has a coating (62) that generally transmits visible radiation while generally reflecting radiation across the infrared range. The window provides for fast and reliable set up of sample and background scans through use of a visual microscope portion of the spectrometer. The window also has a long life, is durable and is low in cost.
