Self-contained, hand-held optical spectrometer
- Los Alamos National Laboratory, NM (United States)
The authors describe the design(s) and performance of a self-contained, portable (hand-held) optical spectrometer. The current instrument is based on a miniaturized monochromator, diode array detector, Peltier cooler and microprocessor control. It can be used either in absorption mode, or in a fluorescence-excitation mode (using an on-board UV penlamp). The unit contains an on-board computer, control pad and LCD display, and can write data to a demountable data key. On-board batteries allow operation for up to three hours in data acquisition mode, or up to twenty-four hours in stand-by mode. The instrument may couple to the sample either fiber-optically, or directly with a light-tight coupling unit. The authors also describe second generation instruments incorporating monolithic optical devices and/or interference filters. In general, these instruments can be made more compact, but at some cost in versatility and information content.
