Details of the design and development of a bright vacuum ultraviolet Seya-Namioka type spectrometer and streak camera system with reflection-type input optics is presented. The Seya-Namioka spectrometer has a 40mm by 45mm holographic grating with a groove density of 600 grooves/mm, linear dispersion of 8 nm/mm, and effective F-number of 4.2. To eliminate loss of light by absorption, the streak camera imaging unit uses Al and MgF2 coated imaging optics with at least 80% reflection from 125-850nm and has an effective Fnumber of 4. It is equipped with a synchronized scan unit that can be tuned to 82MHz and a slow scan speed unit that can measure up to 2- MHz single event. Temporal response of the system at the 20-ns scanning range is evaluated to be around 260 ps.
