CUV-FL-DA Direct-attach Cuvette Holder
The CUV-FL-DA Cuvette Holder attaches directly to
Ocean Optics light sources and
couples via SMA-terminated optical fibers to our spectrometers, creating
an incredibly small-footprint spectrophotometric system for fluorescence
and relative absorbance experiments. The CUV-FL-DA, optimized for UV-VIS-NIR
(200-1100 nm) applications, holds 1-cm square cuvettes and is available
for $461.
The CUV-FL-DA is especially useful for fluorescence measurements.
Mirrored screw plugs strengthen the
fluorescence signal. These reflection mirrors are UV-enhanced
aluminum-coated for 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.
Increased signal intensity is also a result of the CUV-FL-DA's direct
attachment to the light source. With the CUV-FL-DA, users can obtain a
much greater fluorescence intensity compared to signals obtained by using
standard cuvette holders.
Also available is
an adapter piece for linear variable
filters that fits onto a cuvette holder to clamp the filter slide
carriers into place. Ocean Optics cuvette holders can accommodate both
single-filter and double-filter slide carriers. An optional black
anodized aluminum cover can be used to eliminate ambient light and to
block the light path when taking dark current measurements. The CUV-COVER
is $30.
The CUV-FL-DA's 74-UV
Collimating Lens
collects light and
funnels it to the fiber. Collection efficiency, spatial resolution,
transmission angle and acceptance (or collection) angle are adjustable
and easily optimized. The CUV-FL-DA is packaged with the collimating
lens screwed on at a 90° angle from the light source for fluorescence
measurements. However, the lens is removable and can be relocated for
"straight-through" absorbance measurements.
The CUV-FL-DA also features spring-loaded ball plungers
for precise positioning of the 1-cm path length cuvette, a built-in 6-mm
filter slot with filter clamping screw and SMA 905 terminations for
coupling to fiber optics. Two adapters allow the holder to be attached to any
Ocean Optics light source.
"Z" Dimension
All of the cuvettes and cuvette holders offered by Ocean
Optics have a "Z" dimension of 15 mm.
