Description
The design, projected performance and status of NTE (NOT Transient Explorer) is described. NTE is in reality three independent instruments mounted together at the Cassegrain focus of the NOT: NTE-VIS-imager, NTE-IR-imager and NTE-spectrograph. The two imagers can be used in parallel via a dichroic and provides a FoV of 6' with a sampling of 0.18"/pix. They are in performance very similar to AlFOsc and NOTCam, respectively. The NTE spectrograph is a cross-dispersed and covers the spectral range 320 nm - 2430 nm in a single exposure, through 18 spectral orders, with a 23" long slit. The spectrograph utilizes CCDs in the visible/UV and an H2RG detector from Teledyne in the IR, with plate scales of 0.23" and 0.40", respectively. NTE is expected to have first light in 2024.
