Lake Shore Cryotronics has introduced its BPF Series of terahertz (THz) and infrared (IR) band pass filters.
These filters are specifically designed for applications where precision and dependability are paramount, especially when used in extreme environments. BPF series filters are perfect for THz and Fourier transform infrared (FTIR) spectroscopy, materials and THz device characterisation and testing, THz and millimeter wave imaging/security, as well as ground and airborne-based astronomy and astrophysics. The filters block unwanted energy, reducing noise and enhancing signal detection in advanced electro-optical systems, and can also serve as excellent calibration references, providing known frequency/ amplitude profiles. They are specifically designed for use in cryostats and adjacent to ultra-sensitive cooled detectors.
