Abstract

fetched live from OpenAlex

Abstract We discuss the range of tip‐enhanced optical microscopies—namely mapping scattered light, fluorescence, Raman and coherent anti‐Stokes Raman scattering (CARS) signals on the scale of 10–20 nm. Through the use of measurements and finite‐element simulations, we explain what the optimum tip materials and sizes are and illumination wavelengths to use for all these modes of imaging. We also show that the observed limit of 50–100 µW of illumination power is due to a temperature rise of tens of degrees beneath the tip apex, and is most likely linked to the evaporation of water from the tip apex region. This has two important implications—that the tip is surrounded by water even when imaging ‘in air’, and that the tip and sample are both heated when imaging. With emphasis on Raman and CARS, we discuss how both these types of tip‐enhanced optical microscopy can be made about as fast as their diffraction‐limited counterparts.

Full frame distilled prediction

Teacher imitation

Not 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.
