Opto Diode has unveiled a new range of semiconductor radiation sensors that are suitable for identifying photons and other particles.
The product series, which incorporates the IRD AXUV 100GX Absolute X-ray Photodiode, features a small detector footprint and have a large active region with room-temperature operation.
The X-ray detector has 100% quantum efficiency and features active silicon thicknesses. This facilitates in measuring the X-ray flux with 100 keV energies. The AXUV 100GX unit’s responsivity can be calculated from the silicon thicknesses. The IRD X-ray detector does not need an external voltage for operation, unlike conventional X-ray detectors.
The AXUV 100GX diode’s nitrided-oxide front window offers Gigarad of radiation hardness that is greater than conventional PIN silicon photodiodes. Photodiodes with thin-metallic filters can decrease the response to visible light substantially. The sensors are utilized by space and synchrotron scientists for solar spectrum studies.
