First Sensor offers a wide range of photodiodes with high sensitivity, high speed and low dark currents. Our detectors are optimized for ultraviolet, visible and ionizing radiation and can be combined with SMD (surface mount device), THD (through hole device) and TO (metal cans) housing technologies. Our portfolio includes Avalanche photodiodes (APD), PIN photodiodes, position sensitive photodiodes (PSD), and Quadrant photodiodes (QP).
First Sensor provides the ideal emitter for detector solutions. For the wavelength range between 635 nm and 905 nm we carry a wide range of laser diodes (LD). The high-quality lasers are available as single mode or as multimode lasers. For industrial applications, First Sensor offers optimized light-emitting diodes (LEDs) with center wavelengths between 365 nm and 950 nm. The range includes point light sources and surface emitters. We are also happy to adapt the emitter to suit your individual application. Ask us for a customized First Sensor solution.
Atomic particles with sufficient kinetic energy and X-rays can be detected directly via their absorption on the crystal lattice or indirectly via scintillators with silicon radiation detectors. This can require very high absorption volumes and extremely low dark currents, in some cases with fully depleted wafers. First Sensor offers solutions for energy-dispersive spectroscopy. Special features are wafer thickness up to 700 µm, very low dark current signals, very low capacitance level, minimal series resistance at full depletion.
