THz Low Pass Filter Description

THz Low Pass Filter is designed to block frequencies above a specified cutoff while allowing the transmission of lower terahertz signals. Utilising a controlled deposition technique, the filter presents a microstructured interface that reduces scattering losses. This precise frequency discrimination is essential for laboratory research and imaging applications where maintaining a defined spectral range is critical for accurate results.
