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.
