Microrelief diffraction structure recording in LC reactive mesogen
Bibliographic record
Abstract
Reactive liquid crystal (LC) mesogen (trade mark C6M of Merck) is shown to possess efficient relief formation properties. Photosensitive formulation was made by mixing of the reactive LC mesogen C6M with 2% of photoinitiator (Irgacure 651). Photosensitive layer (thickness 70 micrometers ) was obtained by melting the formulation in the gap between two glass substrates. One of the substrates contained a photosensitive silver-halide layer, in which the amplitude mask was recorded with the resolution Fequals40 lines/mm. The amplitude function of the mask represented a phase function of the desired CO2 laser focusing element, designed for wavelength 10.6 micrometers and 45 degrees incidence . Exposure of the reactive mesogen layer through the mask was carried out at elevated temperature of Tequals85 degrees C by UV source (wavelength 365 nm). Immediately after exposure a substrate with photomask was removed and the relief structure in the exposed layer was measured to be ca. hequals1 micrometers deep. After that a dark self-development was allowed resulting in the increase of relief depth h up to 15 micrometers within several hours. The desired hequals7.5 micrometers needed for the most efficient performance of CO2 laser focusing element at 10.6 micrometers and 45 degrees incidence, was stabilized by interrupting self-development with uniform UV exposure of the recorded structure.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
