An internal combustion engine has at least one combustion chamber and a piston slidably disposed within the at least one combustion chamber. More specifically, the present invention provides a processor controlled gaming device that enables the player to build a number of awards by selecting choices from one or more sets of choices and further enables the player to select a final award choice that randomly provides one of the awards when the player finishes building the awards. Analysis set-up data is exchanged through one or more second plug-in software interfaces with one or more data analysis software packages, to configure the processor to provide a predefined subset of the measurement data to the data analysis software packages and to accept analysis results from the data analysis software packages. A plurality of alignment members are coupled to the main body such that each of the alignment members are positioned a predefined distance from the retaining members. The system and method can be applied to two-pass and other multi-pass monochromators and to dual and other multiple serial monochromator configurations using diffraction gratings or other dispersing elements.
