THz Attenuators

    Tydex offers a set of THz attenuators for attenuation of high-power THz radiation.

    The variable wheel attenuator consists of 5 wheels. Four wheels contain metalized wedged silicon wafers with different attenuation levels and one wheel is empty. If necessary the empty wheel can be filled with a custom element (e.g. filter). Four attenuators have transmission 30%, 10%, 3%, and 1%. These attenuator elements can be used as a single attenuator or in combination that allows achieving different levels of attenuation.

    Transmission curves (noise is smoothed) of attenuator elements are shown below. Measurements were made up to 1000 μm. However, operating wavelength range is much wider. It follows from physical mechanism of attenuator operation.

    Transmission values of different combinations of attenuators are given in the table below.
