LDT Instrument List
Upcoming (2021A) Instrument Availability and Configuration
The instrument cube on the Cassegrain focus is currently the only point for mounting instruments on LDT. The instrument cube supports up to 5 instruments at one time; one on the through port, two on the larger side ports (A & C), and two on smaller side ports (B & D). The simultaneous mounting of instruments supports very fast (~2 minutes) changeover between instruments and allows for multiple instruments to be used in a single night (or simultaneously, as in the case of NIHTS & LMI).
Facility Instruments
Large Monolithic Imager (LMI) – available to users the entire semester.
Near-Infrared High-Throughput Spectrograph (NIHTS) – used with a dichroic, available to users the entire semester.
