InAsSb photovoltaic detector


High-speed response and high sensitivity in the spectral band up to 11 μm, infrared detectors


The P13894 series are photovoltaic type detectors that have achieved high sensitivity in the spectral range up to 11 μm using Hamamatsu unique crystal growth echnology and process technology. These products are environmentally friendly infrared detectors and do not use mercury or cadmium, which are substances restricted by the RoHS Directive. They are replacements for previous products that contain these substances. They are compact and easy to handle.
