Qcodes example with Shamrock SR750

from qcodes_contrib_drivers.drivers.Shamrock.SR750 import Shamrock_SR750

Initialize the instrument

shamrock = Shamrock_SR750("Shamrock")

Connected to: Shamrock None (serial:SR-2975, firmware:None) in 8.30s

Get the current spectrometer setup

We read the current grating number, its blaze and groove density, the current central wavelength and the slit width.

print(shamrock.grating.label, ':', shamrock.grating.get(), shamrock.grating.unit)
print(shamrock.blaze.label, ':', shamrock.blaze.get(), shamrock.blaze.unit)
print(shamrock.groove_density.label, ':', shamrock.groove_density.get(), shamrock.groove_density.unit)
print(shamrock.wavelength.label, ':', shamrock.wavelength.get(), shamrock.wavelength.unit)
print(shamrock.slit.label, ':', shamrock.slit.get(), shamrock.slit.unit)

Grating : 1
Blaze : 650
Groove density : 600 l/mm
Wavelength : 600.0 nm
Slit : 200 μm

Change spectrometer setup

We select another grating, change the central wavelength and change the slit width. Afterwards, we repeat the parameter reading.

shamrock.grating.set(2)
shamrock.wavelength.set(756)
shamrock.slit.set(100)

print(shamrock.grating.label, ':', shamrock.grating.get(), shamrock.grating.unit)
print(shamrock.blaze.label, ':', shamrock.blaze.get(), shamrock.blaze.unit)
print(shamrock.groove_density.label, ':', shamrock.groove_density.get(), shamrock.groove_density.unit)
print(shamrock.wavelength.label, ':', shamrock.wavelength.get(), shamrock.wavelength.unit)
print(shamrock.slit.label, ':', shamrock.slit.get(), shamrock.slit.unit)

Grating : 2
Blaze : 675
Groove density : 1350 l/mm
Wavelength : 756.0 nm
Slit : 100 μm

Get spectrometer calibration

We read the spectrometer calibration, i.e. the wavelength for each pixel on the CCD.

shamrock.calibration.get()[:10]

Take a snapshot

We take a snapshot of the instrument to get an overview of the current settings.
