- Stock Linear Variable Filter for 2.5-5.0 µm (2%) “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=2% 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 firstname.lastname@example.org.

Features of 1st Generation Infrared Linear Variable Filters
- 3 ranges covered, 0.9-1.7µm, 1.3-2.5 µm and 2.5-5.0 µm.
- Width/FWHM =2% x Centre Wavelength.
- Blocking greater than OD 2.5 average outside passband.
|Transmission||50-75% across the band|
|Blocking Range||Basic range 1.8-5.5 µm, OD>2.5 ave. outside the transmission band.|
(to extend blocking range a suitable bandpass filter may be added, for custom LVF s extra blocking can be added to the LVF itself)
