Linear Variable Filters
Ocean Optics LVF-series Linear Variable Filters are useful
for spectrally shaping the excitation energy from broadband
sources used for fluorescence. The LVF Adjustable
Bandpass (LVF-HL) filter consists of a linear variable high-
pass and a linear variable low-pass filter that, when used in
tandem, block or pass light in a user-configurable region
from 300-700 nm. The LVF filters provide an easy, affordable
way to restrict wavelengths to a particular region when
performing your fluorescence experiments.
LVF-series Linear Variable Filters also come as part of the
Linear Variable Filter Kit (LVF-KIT), which allows you to
convert your existing Ocean Optics cuvette holders to LVF-
compatible cuvette holders.
The following sections provide instructions on setting up and
using the Linear Variable Filters and Linear Variable Filter
Kit.
Parts Included
The following items are included in the Linear Variable Filter Kit (LVF-KIT). Each of these items can be purchased
individually independent of the LVF-KIT:
•
One LVF-H Linear variable high-pass filter (in a slide carrier)
•
One LVF-L Linear variable low-pass filter (in a slide carrier)
•
One LVF-CUVADPT cuvette adapter
•
Once CDF-DIFFUSE Teflon  diffuser
•
One FHS-LVF in-line sampling optic with collimating lenses
Optional Parts
•
LVF-HH double Linear variable high-pass filter
•
LVF-LL double Linear variable low-pass filter
Part Descriptions
The LVF-H Linear variable high-pass and LVF-L Linear variable low-pass filters are single filter slides epoxied
into slide carriers. These slide carriers are connected back-to-back using four setscrews to create the LVF-HL
Adjustable Bandpass Filter. See the instructions for configuring and using the LVF-HL filter later in this document.
The LVF-CUVADPT cuvette adapter fits over any Ocean Optics cuvette holder to help clamp the LVF-HL slide
carrier in place during experiments. This item can accommodate both single filter and double filter slide carriers.
The CDF-DIFFUSE diffuser is a 1 cm cuvette-shaped piece of Teflon  with a 45
°
angle at the height of the optical
path. Inserted into the cuvette holder during fluorescence applications using the LVF filters and the CUV-ALL-UV
4-way or CUV-FL-DA cuvette holders, it redirects the excitation energy at a 90
°
angle from the excitation source
to the spectrometer. This simplifies the configuration process by eliminating the need to move the collimating
lenses while configuring the bandpass filters.
