- 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 email@example.com.
