For Compactness and Ruggedness, Linear Variable Filters Fit the Bill (Photonics Spectra, Sept. 2016)
REO discusses the latest innovations in design and scalable manufacturing of linear variable filters which has enabled filters that cover a broader wavelength ranges and can be applied as small as 1 mm x 3 mm sizes. We can even produce these very small filters in repeated arrays of LVF's on wafer sized substrates. Authors: Trey Turner, Eric Baltz and Roger Kirschner
