Claim:
1. A sensor device employing electromagnetic radiation, comprising a sensor module and a disposable optical inset module configured to dock with the sensor module, said sensor module being reusable and having an electromagnetic source and a detector thereof; and said disposable optical inset module includes: (a) a cell comprising a conduit or container having an interior that contains a fluid when in use, a first member having a reflective surface and a second member having a reflective surface, said first and second reflective surfaces being at least partially within the interior of the conduit or container and able to reflect electromagnetic radiation emanating from the sensor module; (b) said first member reflective surface and said second member reflective surface are in substantial optical alignment with each other, whereby electromagnetic radiation originating from the sensor module, when docked with the disposable optical inset module, is reflected off said first member reflective surface, travels to and then is reflected off one or more particulates of the fluid or travels to and then is reflected off said second member reflective surface; and (c) a third member having a surface that permits transmission therethrough of electromagnetic radiation reflected off one or more particulates of the fluid, said third member surface being disposed between said first member surface and said second member surface, said third member surface being substantially parallel to the travel of electromagnetic radiation between the first member and second member surfaces.
