Product Name: CUV-ALL-UV 4-way Cuvette Holder for 1-cm Cuvettes
Product Description
The CUV-ALL-UV 4-way Cuvette Holder for 1-cm path length cuvettes is equipped
with fiber optic couplings at each of four quartz f/2 collimating lenses, which
couple to optical fibers to either read or illuminate the sample. When used with
Ocean Optics modular spectrometers and light sources, CUV-ALL-UV Cuvette Holders
can measure absorbance, fluorescence, scattering or any combination of these
optical phenomena.
The CUV-ALL-UV collimators are optimized for measurements from 200 nm-2 µm. The
lenses can be used for "straight-through" measurements, as well as for
scattering or fluorescence measurements. (In some instances, you may wish to
adjust the collimating lenses for precise positioning of the fiber at the lens
focal point.)
The CUV-ALL-UV is $809.
The CUV-ALL-UV Cuvette Holder accepts 1-cm cuvettes; adjustable spring-loaded
pistons hold the cuvette against two reference surfaces. The assembly also has a
built-in ¼" filter slot, which is especially convenient for tailoring (with
bandpass filters) excitation wavelengths in fluorescence measurements.
In addition, for temperature stabilization, the cuvette holder's base plate has
internal channels that can connect to a circulating, constant-temperature water
source.
"Z" Dimension
All of the cuvettes and cuvette holders offered by Ocean Optics have a "Z"
dimension of 15 mm.
Varied Positioning Options
The CUV-ALL-UV offers several options: Position two collimators for
absorbance/transmission measurements of one sample. Or, you can position two
collimators at 90° for fluorescence measurements. Or, position two pairs of
collimators for simultaneous absorbance/transmission and fluorescence
measurements of the same sample. You can even unscrew the collimating lenses
from the holder assembly and use them separately, in any fixture for
applications requiring a fiber for free-beam coupling.
User's Tip
To increase signal collection for fluorescence measurements, add a pair of
74-MSP Mirrored Screw Plugs. These 0.3" (7.5 mm) UV-enhanced aluminum-coated
reflection mirrors connect to the CUV-ALL-UV to provide optimal signal
reflection. One mirrored screw plug collects the fluorescence that would
otherwise be lost; the second screw plug works to reflect the excitation energy
back through the sample. Each 74-MSP is $99.
User's Tip No. 2
Now available are disposable UV cuvettes. A pack of 100 disposable CVD-UV1S
cuvettes for 1-cm path length cuvette holders is just $63. The CVD-UV1S has a
transmission range of 220-900 nm.

** There is no single combination of optical fibers that will satisfy the
requirements of every application. As a rule, however, it is best to use a
large-diameter (>50 µm) illumination fiber to get maximum light throughput and a
small-diameter (<50 µm) read fiber to achieve the best optical resolution.
