First Sensor is a leading supplier when it comes to custom sensor solutions, developed for sophisticated applications with demanding requirements. The manufacturer can also develop solutions in the MEMS and OPTO areas, within a variety of markets. The items are defined by high performance for applications such as detection of pressure, light, radiation, level, acceleration and flow, while the first sensor has a large selection of high-speed, high-sensitivity and low-dark current detectors, which are optimized for infrared, ultraviolet and visible light.
The package solutions proposed include surface mount devices, as well as metal can type and through hole products. The diodes are wavelength sensitive, and utilize the effect of the absorption depth in silicon. There are two p-n junctions specific for this purpose, which are aligned vertically in the silicon crystal. For these purposes, the junctions enable separate signal detection within vertically adjacent ranges.
