DUNEDIN, Fla., Sept. 25, 2015 — The Spark-DET-VIS from Ocean Optics delivers full spectral measurements over the visible wavelength range of 380 to 700 nm. The tiny sensor-only version weighs less than 1 g, making it suitable for high-volume integration into the custom electronics of portable and Internet-enabled sensing devices for environmental, food, agriculture, biomedical and quality-control applications. Measuring simple absorbance, fluorescence and emissive color, the sensor delivers optical resolution of 4.5 to 9.0 nm (full width at half maximum). The device replaces traditional diffraction gratings with a solid-state optical encoder. Its aperture design optimizes light throughput. Robust optoelectronics ensure thermal stability over a –10°C to 60 °C operating range, for accurate analysis even in harsh environments.
