The NISP (Near Infrared Spectrometer and Photometer) is one of the two Euclid instruments (see ref [1]). It operates in the near-IR spectral region (950-2020nm) as a photometer and spectrometer. The instrument is composed of: - a cold (135K) optomechanical subsystem consisting of a Silicon carbide structure, an optical assembly, a filter wheel

The 4m class New Robotic Telescope being built on La Palma, Canary Islands, will build upon the successful autonomous robotic operations model of the Liverpool Telescope. The software stack brings together Telescope Level Systems built using an adaptation from the GranTeCan Control System, with a new Robotic Control System replacing a human

The Laser Guide Star Facility (LGSF) of GTC will generate a laser guide star (LGS) in the high atmosphere for the GTC Adaptive Optics System (GTCAO) to measure and correct the effect of the atmospheric turbulence. The GTCAO LGS Wavefront Sensor (LWS) will be based on a Shack Hartmann WFS and placed on the GTCAO optical bench, where the Natural

This conference presentation was prepared for the Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation V conference at SPIE Astronomical Telescopes + Instrumentation, 2022.

NIRPS is an infrared precision Radial Velocity (pRV) spectrograph covering the range 950 nm-1800 nm. NIRPS uses a high-order Adaptive Optics (AO) system to couple the starlight into a fiber corresponding to 0.4" on the sky as efficiently or better than HARPS or ESPRESSO couple the light in a 1.0" fiber. This allows the spectrograph to be very

The two MAGIC 17-m diameter Imaging Atmospheric Cherenkov Telescopes have been equipped to work also as an intensity interferometer with a deadtime-free, 4-channel, GPU-based, real-time correlator. Operating with baselines between ∼40 and 90 m the MAGIC interferometer is able to measure stellar diameters of 0.5 - 1 mas in the 400-440 nm wavelength
