Optical Filter Wheel - Agilent Technologies Cary 8454 Installation Manual

Optical Filter Wheel

To achieve optimum measurement conditions, optical filters may be
necessary for spectral measurements of photosensitive samples. Agilent
Technologies offers an optical filter wheel assembly (08451- 60302), see
Figure
adjustable cell holder or the thermostattable cell holder. An optical filter
wheel with the same filters but with a different mounting can be used
with the multicell transport, see the multicell transport User's Guide.

The filter wheel rotates to four different positions. Position zero is empty
and permits 100% transmittance at all light wavelengths. Positions one,
two and three have filters which absorb varying amounts of the UV
spectrum.
