Linear Variable Filters (LVFs) from Ocean Insight are handy tools for any optical experiment where high-pass, low-pass or bandpass filters are required. The filters are epoxied into slide carriers so you can move the transmission or blocking band through each filter’s wavelength range. LVFs are available with accessories for mounting the filters in-line or adapting them to the filter slot of a cuvette holder.
LVFs are available in single and double filter versions, have excellent transmission (~90%) and blocking (99.8%) bands and are optimized for 230-500 nm or 300-750 nm wavelength ranges. LVFs are especially useful for spectrally shaping the excitation energy from broadband sources used for fluorescence.
- Versatile – Can be used for high-pass, low-pass and variable bandpass filtering
- Applications – Block excitation energy in fluorescence setups or reduce stray light in absorbance setups
- Adaptable – Acessories for use with cuvette or filter holders
