Meeting abstract
The BTFI (Brazilian
Tunable Filter imager) is a tunable
optical imager designed to supply tunable filter imaging with a
field-of-view
of 3 arcminutes on a side, sampled at 0.12” for
direct Nasmyth seeing-limited area
spectroscopy and for SAM’s visitor instrument port for Ground
layer adaptive
optics, i.e., SAM-fed area spectroscopy.
The instrument has two optical channels which allow for the
simultaneous
recording of the narrow-band image and the remaining (complementary)
broad-band
light. Alternatively the two channels can be used for symultaneous
Fabry-Perot
and broad-band imaging.
BTFI is at the moment capable to achieve spectral resolutions of 1900,
4500 and 20000. In
the future it should reach resolutions from 25-2400 and 6000-30000,
when it is
fully comissioned.
The
workshop on Interacting Systems is a group meeting organized by IAG and
Universidad de La
Serena
and it is funded by the Research Center Labcosmos. The "Science with BTFI
meeting"
happens in the context of LabCosmos and it is mostly funded by INCT-A.
