Cuvette Holders
All types cuvette sample holders are designed for transmission/fluorescence measurements using a
10 x 10 mm cuvette. They feature adjustable clamping to hold non-uniform cuvettes at a repeatable
location. All cuvette sample holders have 5 mm wide slit for filters.
In the following paragraphs the operation instructions for the different cuvette holders are given.
6.2.1
CUV-UV/VIS
The CUV-UV/VIS comes with 2 COL-UV/VIS focusing collimating lenses to maximize the light
throughput. It also comes with a cover to prevent ambient light entering the light path.
Operating instructions:
1.
Attach an SMA terminated optical fiber between the cuvette holder and the light source
2.
Attach an SMA terminated optical fiber between the cuvette holder and the spectrometer
3.
Optionally install a filter by loosening the filter screw and insert the filter into the filter slot,
max filter size is 5 mm.
4.
The cuvette holders are designed to hold 10 mm cuvettes, 2 ball plunger screws can be adjusted
to secure an optimal reproducible cuvette position
5.
Focusing of the 2 lenses: Loosen the set screw of the collimating lens with the Allen Wrench key
1,27 mm on the barrel and slide the inner barrel until you see the optimal signal for your
spectrometer in raw data intensity counts.
6.
Place cover over sample to prevent ambient light entering the light path.
