Segmented Quad InGaAs Photodiodes
OSI Optoelectronics’ Indium Gallium Arsenide (InGaAs) Quad Photodiode series offers extremely low crosstalk between elements, fast response times, and excellent responsivity in the infrared spectrum, from 1100 nm to 1620 nm. Available in 1 mm and 3 mm diameter active areas, the large active area and wide field of view make them perfect for accurate nulling, position sensing, beam alignment, beam profiling, and many more applications.

Silicon (Si) Multi Element Photodiode Arrays

OSI Optoelectronics’ multichannel arrays provide a low-cost alternative when multiple detectors are needed. Optimized for UV, visible, or near-IR wavelengths, our planar diffused silicon photodiodes in 16-, 35-, 38-, and 76-element arrays are ideal for multi-wavelength measurements, level metering, medical equipment, high-speed photometry, position sensing, and more.

Duo Lateral, Super Linear PSDs

OSI Optoelectronics’ one- and two-dimensional photodiodes, the  Duo-Lateral, Super Linear Position Sensing Detectors, feature high-speed response times with extremely low noise levels and capacitance. Our state-of-the art duo-lateral technologies provide a continuous analog output proportional to the displacement of the centroid of a light spot from the center of the active area.

Lateral-Effect Photodiodes Application Note

In recent years, there has been a dramatic expansion of electro-optical instruments. The lateral-effect photodiode provides direct readouts of the displacement of a light spot across its active area.
