| NAME |
FINK SPECTROGRAPH
|
| TYPE |
SPECTROMETER
|
| DESCRIPTION |
The following description is excerpted from Fink et al. 1980. [FINKETAL1980].The Fink Spectrograph was built at the Lunar and Planetary Laboratory and wasdesigned to make optimum use of the CCD array. It employed a transmission gratingand had a spectral range of 5700-11000 Angstroms and a maximum first order resolutionof 11 Angstroms. The long-wavelength limit was determined by the CCD sensitivitycutoff and in practice was close to 1.06 microns. The short-wavelength limitfollowed the sharp cutoff of a Schott OG 570 filter which eliminated overlappingorders.The CCD was manufactured by Texas Instruments and contained 500x500 elements, eachbeing 15.2 microns square. During its operation it was cooled to ~120 degrees C tominimize dark noise. The detector and associated electronics were part of aground-based system built at the California Institute of Technology for use by theSpace Telescope Wide Field Planetary Camera investigation definition team.
