• Spectrum Scanning
• Wavelength Locking

The Micron Optics FFP-Controller is an electronic piezoelectric actuator driver and optical signal processor designed for the FFP Tunable Filter or Scanning Interferometer. It supports multiple operation modes, including manual DC voltage driving, manual DC + AC voltage driving, and automatic wavelength locking to a laser input source via a closed phase lock loop. It is suitable for both new users and advanced research in tunable filters.
