  • OTF-320

Manual Tunable Gaussian Filter

80 nm tuning thin-film dielectric coating based Tunable Filter

  • Gaussian Filter Shape
  • Excellent PDL and PMD
  • Analog Wavelength Indicator
OTF 320

Description

The OTF-320 is a manually tunable optical filter that features a wavelength indicator. Tuning is achieved by rotating a dial on the side of the unit, and the meter on the top of the unit provides the wavelength reference.

A wide choice of tunable filter wavelength range and profile are available from Santec's selection of thin-film based filters.
