|Abstract : ||The Infrared Astronomy Group (IR group) of TIFR has been developing
near-infrared (NIR) instruments for ground based Indian telescopes,
far-infrared instruments for TIFR 100-cm balloon borne telescope
and has recently developed space platforms via IRSIS & other projects.
This talk will present an overview of NIR astronomical cameras developed
by the IR group which have been commissioned / used at various observatories
in India (e.g. IGO, IUCAA,Pune; MIRO, PRL, Mt Abu; HCT, IIA, Hanle,
Ladakh and DOT, ARIES, Devasthal, Uttarakhand).
TANSPEC Optical-NIR spectrograph is installed (Apr 2019) and
commissioned at DOT 3.6 meter telescope. TIRSPEC NIR imager and
spectrometer was commissioned at 2 meter HCT, Hanle in 2014 and is currently being
used for science observations. TIRCAM2 NIR imager has been used at MIRO,
IGO and is currently installed at the side port of DOT 3.6 meter
telescope. Talk will also cover a brief overview of the IRSIS satellite
payload related work.|
