Abstract
A Czerny–Turner type spectrometer has been designed and operated as a rapid scanning instrument by placing a rotating mirror near the exit slit. Using a helium–neon gas laser, resolution of 0.027 Å has been measured at scanning rates of 0.4 Å/μsec. Data have been taken with the scanning rate of 6 Å/μsec, which could have been increased an order of magnitude if desired. A scanning range of 1–600 Å depending on the grating and mirrors used has been obtained. Applications shown included the shift and shape of xenon spectral lines in a pulsed arc discharge. The associated electronics required for synchronization are included.
