Fig. 1From: Compact orthogonal-dispersion device using a prism and a transmission gratinga Optical layout of the prism-grating device, in which the prism disperses the incident light along z-axis, the grating normal is parallel to y-axis, and the grating grooves are parallel to z-axis. b Ray tracing in the sagittal plane (i.e., x´-y´ plane). c Ray tracing in the meridian plane (i.e., y´-z´ plane)Back to article page
