May 6, 2014 - As standard package for operator field use, UDS-1100 allows simultaneous capture and plotting of upwelling and downwelling radiation in 320–1,100 nm range. Features include 512-element photo diode array, 4° weather-proof FOV lens, and diffuser receptor. With PC attached via USB or optional Bluetooth® connection and DARWin SP DAQ software, operator can collect scans. Optional unattended standalone configuration (UDS-1100SA) can collect scans automatically at user-specified intervals.

Simultaneously Measure Upwelling and Downwelling with a Field Unit or in a Standalone Configuration.

The UDS-1100 and UDS-1100SA field spectroradiometers capture both measurement modes across a 320-1100nm spectral range.

Lawrence, MA — The SPECTRAL EVOLUTION UDS-1100 allows you to simultaneously capture and plot upwelling and downwelling radiation in the 320-1100 nanometer range. The UDS-1100 is available in two configurations: as a standard package for operator field use, and the UDS-1100SA, an unattended standalone configuration.

The UDS-1100 uses a single, 512-element photo diode array. Using a 4° weather-proof field-of-view (FOV) lens for upwelling radiance data and integrated diffuser receptor for downwelling irradiance, the UDS-1100 is NIST-calibrated and available in a rugged NEMA enclosure for field installation.

With a PC attached through a USB or optional Bluetooth connection and loaded with DARWin SP Data Acquisition software, an operator can collect scans. The optional UDS-1100SA can be set up to collect scans automatically at user-specified intervals. In standalone configuration the system includes a re-chargeable lithium-ion battery that can scan continuously for up to 24 hours. This configuration collects and stores up to 2500 scans before it requires off-loading via a PC.

The UDS-1100 is well-suited for a range of applications, including:

• Soil and crop studies
• Research into the spectral characteristics of vegetation, including plant canopies
• Forest canopy studies accounting for the effects of light and shade on leaves and soil
• Ocean, seabed, and water body studies looking at chlorophyll concentration for sea grass and coral reef health
• Snow and ice studies as part of environmental research
• Weather station research including studies on UV and variations in long-term radiation
• Meteorological measurements at remote locations

The UDS-1100 and UDS-1100SA weigh four pounds, use a USB interface for communications, are compact at 10 inches by 12.5 inches by 6 inches, and can be mounted on a tripod or wall-mounted or pole mounted with a bracket depending on the installation. The rugged plastic NEMA case ensures reliable high performance. For installations that require greater battery power, for example a 12V automotive or marine battery, optional power connectors are available.
