pylabrobot.plate_reading.plate_reader.PlateReader.read_absorbance# async PlateReader.read_absorbance(wavelength: int, wells: List[Well] | None = None, **backend_kwargs) → List[List[float | None]]# Read the absorbance from the plate in OD, unless otherwise specified by the backend. Parameters: wavelength (int) – The wavelength to read the absorbance at, in nanometers. wells (List[Well] | None) Return type: List[List[float | None]]
