Visible Light Wavelength Tunable Filter with Exchangeable Filter (VTFM/FC)

TFM/FC contains an optical filter mounted on a cassette. By exchanging the cassette, TFM can change its spectral characteristics including the tunable wavelenth range. This type TFM can tuning visible ligth wavelength.

Please inquire us.

  1. Combining TFM with light source. 
  2. Selection filter takes out some of the required wavelength.
  3.  FC can tuning the wavelength by 10 nm.
