3: Using the Curie System
• The UV LVF filter can be used to select excitation energy in the 230 to 500 nm range. The
bandwidth is fixed and varies from 30 to 40 nm. For UV excitation light, adjust the UV LVF filter
to select your wavelength range. The UV LVF filter is used with the UV (Cold) mirror (Mirror
Adjustment knob turned so that the UV label is closest to the cuvette holder – see
• The VIS LVF filter can be used to select excitation energy in the 300 to 750 nm range. The
bandwidth is fixed and varies from 30 to 40 nm. For VIS excitation light, adjust the VIS filter to
select your wavelength range. The VIS LVF filter is used with the standard mirror (Mirror
Adjustment knob turned so that the VIS label is closest to the cuvette holder – see
Using the CVD-DIFFUSE
A white, cuvette shaped CVD-DIFFUSE is provided with your Curie system (stored in the side storage
door of the Curie) to help you select the excitation wavelength for your measurement. With the detector
located at 90 degrees relative to the light source, the CVD-DIFFUSE provides a way to deflect the light
energy into the detector. The CVD-DIFFUSE is a 1-cm piece of PTFE material used to deflect the light
from the light source into the spectrometer. Insert the CVD into the Curie’s cuvette holder as shown in the
figure below.
Selecting the Mirror for Use with the LVFs
There are two mirrors available in the Curie system:
• Standard mirror – (Mirror Adjustment Knob turned with VIS label closest to the cuvette holder).
Reflects visible and UV light from the light source into the cuvette holder. Use this mirror setting
with the VIS LVF filter. In the figure below, the spectrum of the xenon lamp reflected off of the
standard mirror is shown.
