Spectroscopic ellipsometry of a-Si/SiO 2 large waveband coating for the JWST-FGS-TFI etalon plates fabrication
Bibliographic record
Abstract
Previous publications for the JWST-FGS-TFI instrument described the design and fabrication of mirror coatings for scanning Fabry-Perot etalons. Since that time, we have extended the fabrication process using ellipsometry analysis over the full operational bandwidth from 1.0 to 5.0 microns for both mirror and anti-reflection coatings. This paper will present single and multiple layer ellipsometry analysis of the a-Si/SiO<sub>2</sub> optical properties. Analysis improvement came from a-Si/SiO<sub>2</sub> interface consideration and simultaneous use of ellipsometric data from Woollam V-VASE and IRVASE instruments. Simulations of reflectance and transmittance based on the ellipsometric analysis results will also be compared to spectrophotometric measurements for witness pieces.

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.
