wavelength#
method
- TSL550.wavelength(val: float = None) float[source]#
Sets the output wavelength, and returns nothing.
If a value is not specified, returns the currently set wavelength. The wavelength value is in nanometers. The minimum step size is 0.0001 nm.
- Parameters:
- valfloat, optional
The wavelength the laser will be set to in nanometers.
- Returns:
- float
The currently set wavelength, in nanometers.
Examples
You can get the current wavelength by calling without arguments.
>>> laser.wavelength() 1630.0
The following sets the output wavelength to 1560.123 nanometers.
>>> laser.wavelength(1560.123)
