The spatial resolution would depend on proximity to grating. The father away, the larger the pixels or scan integration areas (or, step size) could be. Most compact spectrometers fold the optical path using mirrors to increase the path length. Some also include a concave mirror to match the Rowland circle and project a more linear distribution of frequencies.
