Abstract
An exciting part of the astrophysical spectrum is the far-ultraviolet (FUV: 90 to 180 nm), with a great density of absorption and emission lines. We are planning to develop an imaging spectrograph incorporated into a 6U (300 × 200 × 100 mm3) satellite to observe di use nebulae. The field of view is 4 × 1′ with a spatial resolution of 13 and a spectral resolution of 0.6 Å (Resolution 2000). In this work, we present the selection of the components and the optical design of the spectrograph using hand calculations and Zemax software. To determine the positions of the components, ray tracing (sequential) is done.
