catalight.equipment.light_sources.nkt_collect_calibration.growing_window_test(start, end, step, bandpass, meter)

Expands the bandwidth of the laser and records power at each step.

The first measurement is taken at [start, start + step]. The function will detect whether the window should grow towards longer or shorter wavelengths start - end must be <= 100 nm

Parameters:

• start (int or float) – Starting wavelength for sweep

• end (int or float) – Ending wavelength for sweep

• step (int or float) – Step size between start/end points.

• bandpass (nkt_tools.varia.Varia) – Computer controlled bandpass filter for laser

Returns:

A dataframe with columns [‘Wavelength’, ‘Meter Reading’]

Return type:

pandas.DataFrame
