CHIMERA Technical Specifications
CHIMERA: a wide-field, multi-colour, high-speed photometer at the prime focus of the Hale telescope (2016) L.K. Harding, G. Hallinan, J. Milburn, P. Gardner, N. Konidaris, N.Singh, M. Shao, J. Shandu, G. Kyne and H.E. Schlichting MNRAS 457, 3036-3049.
CHIMERA uses two Andor iXon Ultra DU-888, cameras for the red and blue channels. The iXon Ultra 888 cameras contain CCD201-20 EMCCD detectors from E2V.
Platescale: 0.29 arcseconds/pixel, 13μm pixels.
Each channel of the CHIMERA instrument contains a filter slide mechanism with 4 filter positions (not all are populated). The dichroic transmits light in the 570 to 850nm wavelength range into the RED camera and reflects light from 300 to 540nm into the BLUE camera. The primary broadband filters in the instrument are Sloan filters covering the wavelength range from 320nm to > 1000nm.
The empirically measured optical throughput of the system for each of the Sloan filters is summarized below:
