Abstract:
Reliable calibration of astronomical
data from large telescopes is an essential factor in obtaining
high sensitivity observations for both the astronomer at the
telescope and the archive researcher. A dedicated calibration
unit provides an efficient and predictable method of observing
calibration frames. Such a facility is being designed for the
Gemini telescopes. It is required to calibrate instruments with
wavelengths from the UV to the infrared, covering a broad range
of both spectral and spatial resolution. We will present the
design of this calibration unit and the predicted performance
with the `first-light' Gemini instruments.
Keywords: calibration, diffusing systems, uniform
illumination, observing efficiency
