- Stock Linear Variable Filter for 1.3-2.6 µm (1%) “on the shelf” for next day shipping, 15 mm x 3.5 mm x 0.5mm thick
- This linear variable filter (LVF) has a narrow band profile (FWHM=1% x Peak Wavelength).
- The peak wavelength changes continuously from one side to the other across the range, see right in Fig 1.
- All of our filters exhibit high angular tolerance, extremely low change with temperature and very high resistance to thermal shock.
- Different sizes of this LVF are also possible to suit the user’s detector window dimensions, contact us for further details on enquiries@vortexopticalcoatings.co.uk.

Features of 2nd Generation Infrared Linear Variable Filters
- 2 ranges covered, 0.9-1.7µm and 1.3-2.5 µm.
- Width/FWHM =1% x Centre Wavelength.
- Blocking greater than OD 3.5 average outside passband.
- For systems where higher signal to noise ratio is critical.
Applications
These LVF s can be used for compact mini spectrometers, gas analysis, plastics identification, a range of filters can be replaced with one linear variable filter.
