Contents:
1. design of normal-incidence spectrograph with ZEMAX
2. optical quality of the single-mirror off-axis telescope
3. possibility of three wavelength ranges between 58 nm and 126.8 nm
4. design of focal plane with 116.8 nm to 126.8 nm channel
5. some thoughts on thermal aspects:
a) Semi-transparent telescope mirror
b) Heat rejection mirror

Based on previous design of Roger Thomas:
• development of varied-line-space grating surface for ZEMAX
• ZEMAX calculation with ellipsoid VLS grating
• modified RT design for longer wavelength channel
