Linear Variable Filter - List of Manufacturers, Suppliers, Companies and Products

Linear Variable Filter: LVF [Multiple interference filters combined into one!!]

It is an optical interference filter that can cut and transmit various wavelength ranges with a single sheet.

The linear variable filter is a wedge-shaped filter with a wavelength characteristic that varies linearly. By sliding the light incidence position, it is possible to continuously change the transmitted wavelength. The transmittance is over 90% (slightly varying by wavelength), and with a block rate of OD 3 or higher, it can be installed in front of sensors to obtain data with minimal noise. 【Features】 ■ Achieves minimal self-fluorescence and a high laser damage threshold with a robust, shift-free surface coating on a non-adhesive quartz substrate. ■ Can be used as a secondary light cut filter for spectrometers. ■ High compatibility filter with SC light sources. ■ Transmittance exceeding 92% in most cases. ■ Block rate higher than OD 3. ■ By stacking another LVF, the block rate exceeds OD 5. ■ Useful application notes available.
