Can I use a linear variable filter for absorbance and other applications?

Yes. Although conceived with fluorescence applications in mind, linear variable filters can be used to reduce the stray light in absorbance measurements by limiting the illumination light to the wavelength band of interest. The LVF-HL lets you adjust both the wavelength and bandwidth of the filtering. The filter can be used either in-line or in a cuvette holder on either the illumination or read side of the holder.

 

Also, LVF filtering techniques can be used to eliminate second-order effects for spectrometers without built-in filters and limit photodegradation by reducing the energy in wavelength bands that are not needed for the application.
