Optical Arc Detectors

Description
CML Optical Arc Detectors provide optical detection of arcs within waveguides or RF cavities. They are sensitive to a wide range of optical wavelengths in the visible and near infrared spectral region. They are normally supplied installed on an E-Plane or H-Plane waveguide bend as pictured here. The waveguide bend is equipped with a small below-cutoff aperture for viewing of regions where an arc may occur. An optional reverse power input is available. This input allows triggering on reflected power from the output of a diode detector installed on a reverse power monitoring directional coupler. The arc detector circuit assembly can also be supplied on a mounting plate for field replacement or for mounting on a viewport for vacuum waveguide applications. This circuit assembly is designated as Model 6280-00
