Facility integration of the NASA IRTF adaptive secondary mirror
Ellen Lee, Mark Chun, Michael Connelley +12
IRTF-ASM-1 has been functioning well since its first light in 2024. This adaptive secondary mirror (ASM) was primarily developed to be an on-sky demonstration of the new hybrid var…
Progress report on the integration of the IRTF adaptive secondary mirror
Ellen Lee, Mark Chun, Ruihan Zhang +13
IRTF-ASM-1 is the first on-sky adaptive secondary mirror using the hybrid variable reluctance (HVR) actuators developed by the Netherlands Organization for Applied Scientific Resea…
Design and Performance of the Upgraded Mid-InfraRed Spectrometer and Imager (MIRSI) on the NASA Infrared Telescope Facility
Joseph L. Hora, David E. Trilling, Andy J. Lopez-Oquendo +12
We describe the new design and current performance of the Mid-InfraRed Spectrometer and Imager (MIRSI) on the NASA Infrared Telescope Facility (IRTF). The system has been converted…
In-lab and On-sky Closed-loop Results of Adaptive Secondary Mirrors with TNO's Hybrid Variable Reluctance Actuators
Ruihan Zhang, Max Baeten, Mark R. Chun +8
We performed closed-loop lab testing of large-format deformable mirrors (DMs) with hybrid variable reluctance actuators. TNO has been developing the hybrid variable reluctance actu…
First laboratory and on-sky results of an adaptive secondary mirror with TNO-style actuators on the NASA Infrared Telescope Facility
Ellen Lee, Mark Chun, Olivier Lai +14
We are developing an adaptive secondary mirror (ASM) that uses a new actuator technology created by the Netherlands Organization for Applied Scientific Research (TNO). The TNO hybr…
