OSI SPOT Series Segmented Photodiodes The SPOT Series of common substrate photodiodes, from OSI Optoelectronics, are segmented into separate active areas with a well defined 0.127mm gap between adjacent elements. SPOT Series photodiodes have a spectral response range of 350-1100nm; Notch or band pass filters can be added to achieve specific spectral responses.
Position information can be obtained when the light spot diameter is larger than the spacing between cells. High Accuracy
Position resolutions of better than 0.1μm
Fast response times suitable for high speed or pulse operation
Ultra Low Dark Current
Excellent Response Match
High Stability over Time and Temperature
Applications include: Machine Tool Alignment, Position Measuring, Beam Centring, Surface Profiling and Targeting Guidance Systems
