A method of determining beryllium or a beryllium compound thereof in a sample is disclosed by measuring fluorescence. An array of hermetically sealed, multiple individual organic light emitting diodes are positioned within the peripheral boundary on top of the first layer of ice. The scanning subsystem includes the handheld scanning device; a polygon mirror adapted to rotably reflect a light path originating from the handheld scanning device, the light path disperse into a pattern for scanning a symbol. The computer is further operative to direct the CNC machining platform to machine a lap tool for each lens and machine a block for receiving each lens.
