InAsSb photovoltaic detector


Back-illuminated type infrared detector with band-pass filter (3.9 μm ・ 4.26 μm)


The P16849-012CF is a two-element type that can detect two wavelength InAsSb photovoltaic detectors.  By using a back-illuminated structure, we greatly improved the sensitivity temperature coefficient compared to the front-illuminated type. That uses two types of band-pass filters with center wavelength of 3.9 μm and 4.26 μm for the window. Products using two filters are suitable for gas measurement. It is environmentally friendly infrared detectors and do not use lead, mercury, or cadmium, which is substances restricted by the RoHS directive.
