The optical design of wide integral field infrared spectrograph
Bibliographic record
Abstract
We present the optical design of the Wide Integral Field Infrared Spectrograph (WIFIS) which provides an unprecedented combination of the integral field size and the spectral resolving power in the near-infrared wavebands. The integral field size and spectral resolving power of WIFIS are ~ 5× 12on a 10-m telescope (or equivalently 13× 30on a 4-m telescope) and ~ 5300, respectively. Therefore, the affordable etendue of WIFIS is larger than any other near-infrared integral field spectrographs while its spectral resolving power is comparable to the highest value provided by other spectrographs. WIFIS optical system comprises an Offner relay-based pre-slit unit, an image slicer for integral-field unit, a collimator, diffraction gratings, and a spectrograph camera. For the integral field unit, WIFIS uses the Florida Image Slicer for Infrared Cosmological and Astrophysics which is a set of 3 monolithic mirror arrays housing 22 image slicers. The collimator system consists of one off-axis parabola and two lenses, while WIFIS relies on 3 different gratings to cover the entire JHK bands. The spectrograph camera uses 6 lenses of CaF2 and SFTM16, delivering the f/3 final beam onto a Hawaii II RG 2K × 2K detector array. WIFIS will be an ideal instrument to study the dynamics and chemistry of extended objects.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
