TFP Technology

The TFP-2 HC employs a compound parallelogram translation stage that ensures linear, tilt-free mirror movement with sub-angstrom precision. This design eliminates common issues found in traditional Fabry-Pérot setups—such as non-linear scanning and mirror tilt—resulting in highly stable and repeatable measurements essential for high-resolution spectroscopy.

At the heart of the TFP-2 HC is its tandem configuration: two triple-pass Fabry-Pérot interferometers aligned on a shared scanning axis. This arrangement dramatically increases contrast and resolution, enabling the system to suppress unwanted spectral components and isolate weak Brillouin signals with exceptional clarity.

The optical layout integrates quarter-wave antireflection coatings and spatial filtering techniques to minimize cross-talk and maximize throughput. These enhancements allow the TFP-2 HC to achieve contrast ratios exceeding 10¹⁵, making it ideal for detecting subtle spectral features across a broad frequency range.

To maintain consistent performance, the TFP-2 HC uses capacitive sensors for real-time mirror spacing feedback and incorporates thermal isolation strategies throughout its frame. These features ensure long-term stability and reduce drift, even under varying environmental conditions—critical for demanding research applications.
