The spectral responsivity range of the model UV-3711 covers the UV-B range from 280-320 nm General Purpose UV Radiation Measurement Detector The UV-37 series of UV radiometric detectors are primarily used for spectral broadband irradiance measurements within a defined spectral range of polychromatic radiation. Optical filters are used to shape the bare photodiode response to the desired spectral bandpass. The computer aided optical filter design produces the best possible broadband radiometric response within the spectral sector specified. Pre-aged Components All optical and optoelectronic components of the UV-37 detectors are UV Radiation pre-aged for Long time stability. Cosine Field-of-View A cosine F.O.V. characteristic of the detectors spatial responsivity is effected by the diffusor window of UV-37 detectors. Designed for Wide Dynamic The UV-37 detectors are designed for the highest possible irradiance sensitivity for low irradiance level applications. However the wide range linearity of the photodiodes coupled with the Gigahertz-Optik optometers’s wide dynamic signal range amplifiers enable the UV-37 series detectors to be used in applications with high irradiances as well. The upper range is limited only by the detector maximum operating current and its specified operation temperature. Compact Housing The UV-37 series irradiance detectors are built in a compact 37mm diameter black anodized aluminum housing. The shadow ring around the diffusor support the wide-angle cosine response. A side M6 tapped mounting hole allows the detector be fixed in place.
