UVD and UVE photodiodes

OSI Optoelectronics (OSIO), a supplier of standard and OEM photodiodes and high-power light sources, now offers UV-enhanced planar diffused silicon photodiodes specially designed for low-light-level detection in the ultraviolet spectral range. The product series includes the UVD planar diffused and UVE planar diffused IR suppressed devices, both featuring excellent UV response.

The UVD and UVE photodiodes exhibit significant advantages over technology used in competing devices such as inversion layer photodiodes, including lower capacitance and higher response times. OSI Optoelectronics’ UVD photodiodes peak at 970 nm. The UVE devices peak at 720 nm and suppress the near-infrared, making them particularly useful in applications where blocking the NIR spectral region is required. Both products can be biased for lower capacitance, wider dynamic range, and high speed response times. Alternatively, the UVD and UVE series may be operated in the photovoltaic (unbiased) mode for situations that require low drift with temperature variations.

Available in varying sizes and footprints, in metal or ceramic packages, OSI’s UV-enhanced planar diffused Si photodiodes are ideal for applications in medical instrumentation, pollution monitoring, spectroscopy, fluorescence, water purification, UV exposure meters, and more
