ARNICA and LonGSp are two NICMOS based near infrared instruments developed in the 90's by the Astrophysical Observatory of Arcetri. After more than 10 years from decommissioning we refurbished the two instruments
with a new read-out electronics and control software. We present the performances of the refurbished systems
and compare them with the historic behavior. Both instruments are currently used for testing purposes in the
Lab and at the telescope, we present some example applications.
