Last month we began in this column a discussion of diffraction gratings. We continue this month by covering reciprocity, the resolving power, Littrow mount, blazed gratings, and dielectric-coated transmission gratings. Please note that some of the figures and references discussed in July are cited here. You will need to refer back to the July issue, pages 42-46, as the figure and reference numbering scheme continues here.
