Product details
Pomona Electronics's 4957 revolutionizes Coaxial Connectors (RF) connectivity for terahertz imaging systems. Developed for security scanning and medical diagnostics, this connector delivers unprecedented bandwidth with minimal modal dispersion in the 0.1-10THz spectrum.The BNC, Twinaxial interface features photonic crystal fiber alignment for optimal Gaussian beam coupling. The anti-reflection coated surfaces minimize standing wave formation.Utilizing Plug, Female Socket and Male Pin topology, the connector achieves <0.01dB/mm attenuation at 1THz. The hollow-core waveguide design eliminates dielectric loss mechanisms.Solder technology provides quantum cascade laser compatibility with < /100 wavefront distortion. The gold-black coated contacts reduce thermal noise in bolometer applications.With Clamp methodology, the connector exhibits >80dB isolation against substrate modes. The corrugated horn design ensures pure HE11 mode propagation.Optimized for Free Hanging (In-Line) integration, the connector maintains <5 m alignment tolerance. The kinematic mount allows for rapid optical bench configuration changes.Validated with RG-108, 108A, Belden 9272 waveguides, the connector demonstrates <0.1ps group delay dispersion. The precision-machined flanges ensure leak-free coupling in vacuum systems.The Bayonet Lock mechanism provides sub-wavelength positional accuracy with <1 m repeatability. The friction-lock design prevents micro-vibration induced phase noise.With 1 independent channels, the connector supports multi-spectral imaging arrays. Each port features integrated beam collimation optics.The Silver housing material exhibits <0.001 absorption coefficient at THz frequencies. The diamond-turned surface finish minimizes scattering losses.The Beryllium Copper formulation provides <10nm RMS surface roughness. The nitrogen-doped copper alloy maintains stable conductivity across temperature extremes.
