Thorlabs Power Meters¶
Driver module for Thorlabs power meters. Supports:
- PM100D
-
class
instrumental.drivers.powermeters.thorlabs.PM100D(visa_inst)¶ A Thorlabs PM100D series power meter
-
__init__(visa_inst)¶
-
auto_range_enabled()¶ Whether auto-ranging is enabled
Returns: bool Return type: enabled
-
close()¶
-
disable_auto_range()¶ Disable auto-ranging
-
enable_auto_range(enable=True)¶ Enable auto-ranging
-
get_num_averaged()¶ Get the number of samples to average
Returns: num_averaged – number of samples that are averaged Return type: int
-
get_power()¶ Get the current power measurement
Returns: power – the current power measurement Return type: Quantity
-
get_range()¶ Get the current input range’s max power
-
get_wavelength()¶ Get the input signal wavelength setting
Returns: wavelength – the input signal wavelength in units of [length] Return type: Quantity
-
measure(n_samples=100)¶ Make a multi-sample power measurement
Parameters: n_samples (int) – Number of samples to take Returns: Measured power, with units and uncertainty, as a pint.MeasurementobjectReturn type: pint.Measurement
-
set_num_averaged(num_averaged)¶ Set the number of samples to average
Each sample takes approximately 3ms. Thus, averaging over 1000 samples would take about a second.
Parameters: num_averaged (int) – number of samples to average
-
set_wavelength(wavelength)¶ Set the input signal wavelength setting
Parameters: wavelength (Quantity) – the input signal wavelength in units of [length]
