This software allows you to select and execute Python scripts from a file whilst LightField™ is running.
The required Python version is 3.14.
As the Add-In itself contains wrapper functions for LightField,
it is very easy to write measurement routines. For example, to measure a spectrum whilst sweeping the
wavelength of the excitation laser (PLE), you can use code (excerpt) such as the following. Once the script
has finished running, you can run the same or a different script again.
Sample code for PLE and mapping measurements is included, so you can easily automate your measurements by
modifying these examples.
for loop in range(3):
laserWavelength=float(loop)*10.0+800
print(f"{laserWavelength=}\n")
#change laser wavelength
laserControl.SetWavelength(laserWavelength)
#acquire image
runPython.Acquire(True)
LightField provides complete timing control for Princeton Instruments's ICCD cameras. Using the ICCD camera
with short pulsed laser, it can takes time resolved images. This "AddIn" can analyze the decay time from
those images and make the decay time image.
・Decay analsys at a certain point
・Decay analsys for whole image
WinSpecTM can control cooled CCD of
Princeton Instruments and spectrograph. With the microscope, these system can measure microscopic
photoluminescence and/or raman scattering light.
The data of these microscopic spectroscopy provides the knowledge of micro area. This SnapIn adds the
function of stage control to WinSpec.
・ Support mortorized stage (SIGMA KOKI, SIGMA TECH, CHUO PRECISION, etc.)
・ Image construction by peak wavelength, intensity, FWHH (Gaussian/Lorentzian fitting support), etc.
・ Support color camera for capturing the image. Can select area from captured image.
Photoluminescence excitation (abbreviated PLE) is photoluminescence and concerns the interaction between
electromagnetic radiation and matter.
The luminescence is monitored at CCD with spectrograph and the frequency of the excitation light will be
varied.
This SnapIn controls laser wavelength and monitored wavelength by wavemeter (optional).
