Preparation and characterization of quarter-wave plate at 12.4 μm based on CdSe single crystal
Bibliographic record
Abstract
Abstract CdSe single crystal with good optic properties is great candidates for optical devices. In this paper, CdSe single crystal was grown by the modified vertical unseeded vapor sublimation method with the diameter of 36 mm and the length of 40 mm. The quarter wave plates of CdSe single crystal with size of 20 mm × 20 mm × 3 mm was cut along the (001) orientation. The transmittance of the CdSe wave plate was about 69% in the range of 8–14 μ m, where the absorption coefficient was about 0.04 cm −1 . The phase delay was 90.71176° at 12.4 μ m, which less than 5%. This work disclosures a high-quality and large size wave plate of CdSe single crystal, such wave plate has wide application prospects in mid-infrared.

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.
