“…For example, it has long been known that sources for atomic spectroscopy-including flames, inductively coupled plasmas, microwave plasmas, and glow discharges-exhibit such heterogeneity. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] A number of approaches have been used to obtain spatial resolution with optical probes. Point-by-point measurements can be made with relatively simple, sensitive, and inexpensive instrumentation.…”

“…It has been used to examine inductively coupled plasmas (ICP) [8][9][10][11][12][14][15][16][17][18] and glow discharges. 13 It has been used both to study the fundamental properties and processes of plasmas 8,10,11,13,14,[16][17][18] and to optimize the performance of plasmas. 9,12,15 In the MIS described by Olesik and Hieftje, 19 displayed schematically in Fig.…”

Distortion inherent to a previously described system for acquisition of two-dimensional monochromatic spatial images is described. A solution is offered in the form of an improved instrument. The system uses a Czerny-Turner monochromator for spectral discrimination and a charge-coupled device (CCD) as the detector. A second Czerny-Turner monochromator, with identical dimensions, is added to correct the distortion, albeit with a slight loss in spatial resolution. With the earlier uncorrected arrangement, spatial resolution was on the order of 0.1 mm vertically and 0.3 mm horizontally, with a magnification of 0.52. With the same magnification, the new, corrected system offers spatial resolution of 0.1 mm vertically and 0.4 mm horizontally.
