TIFR treasures for astronomy from ground to space

The infrared astronomy group of Department Astronomy and Astrophysics at Tata Institute Fundamental Research has been pursuing astronomical instrumentation activities since its inception. routinely involved in balloon-borne programs from the field station Hyderabad with indigenously developed payloads. Ground-based began a single element detector. Later, over time, larger format array detectors are being used cameras. These cameras have observatories across India. Recently, also laboratory model Infrared Spectroscopic Imaging Survey payload, targeted for small satellite mission Indian Space Organisation, which will carry out spectroscopic measurements wavelength range 1.7 to 6.4 $\mu$m seamlessly
