USB-LS-450 LED Light Source ModuleThe USB-LS-450 is an integrated, multi-purpose LED light source module designed for use with either aUSB4000-FL Spectrometer(or its predecessor, the USB2000-FL Spectrometer), a small-footprint, plug-and-play spectrometer that plugs into the USB port of any desktop or notebook PC. The USB-LS-450 is available for only $635 and can be used for general fluorescence measurements or as part of aFiber Optic Oxygen Sensorsystem.FeaturesSimplified LED-spectrometer interface--LED connects to spectrometer, whichplugs directly into Universal Serial Bus port of any desktop or notebook PC.Small footprint-- LED-spectrometer combination is about the size of a deck-and-a-half of playing cards.On-board memory for oxygen measurements--Fiber Optic Oxygen Sensor users canconveniently store calibration temperature calibration coefficients and oxygen calibration coefficients.No external powerrequirements-- Spectrometer and LED draw power from the PC.The USB-LS-450 module connects to the USB Series spectrometers via a connector on the front of the spectrometer. The spectrometer provides power to the LED and also enables synchronization functions and I2C communications.In addition, the USB-LS-450 features a built-in, 24-bit analog-to-digital converter with an analog front end that is configured for a 100 ohm platinum RTD (resistance temperature device). This is particularly useful when configured as part of a Fiber Optic Oxygen Sensor. In fact, the unit has on-board memory to store temperature calibration coefficients and oxygen calibration coefficients.The USB-LS-450 can provide 4-20 mA output via a daughter card, making it especially useful for process applications.User""""""""""""""""s Tip:The USB-LS-450 board allows for software-controlled switching between pulsed and CW operation of the LED.USB-LS-450 Spectral OutputUSB-LS-450 LED SpecificationsCriteriaSpecificationPower output:60 µW into a 600 µm optical fiberLED drive current:20 mA +/-150 mAMaximum modulation frequency:1 kHz0.5% stability time:less than 1 minuteTemperature-dependent drift:+0.1%/ºCTemperature Measurement SpecificationsCriteriaSpecificationPrecision:better than 0.1 °CAccuracy:better than 0.5 °CMaximum data rate:15 samples/secondPower RequirementsCriteriaSpecificationInput voltage range:3.0-8.0 voltsQuiescent range:~20 mACurrent with light on:~20 mAOrdering InformationItemDescriptionPriceUSB-LS-450LED drive module for use with USB Series Spectrometers$635USB-LS-450-TPPlatinum RTD-type temperature probe for USB-LS-450$115USB-LS-450-4/204-20 mA output module for USB-LS-450Call for PriceUSB4000-FLSpectrometer with a 360-1000 nm range; should be specified when used with USB-LS-450 and Oxygen Sensors$2887Sample Oxygen Sensor System Order with USB-LS-450 and AccessoriesItemCommentsPriceSpectrometer:USB4000-FL Spectrometer (360-1000 nm)$2887USB-LS-450 Excitation Source:Blue LED drive module$635USB-LS-450-TP Temperature Probe:Platinum RTD-type temperature probe (optional)$115USB-LS-450-4/20 mA output:4-20 mA output module for process applications (optional)Call for PriceProbe:Select from 6 standard options (contact anApplications Scientistfor details)Depends on probe selectedFiber:Bifurcated optical fiber (200 µm, 400 µm or 600 µm; selection depends on probe specified)Call for Price21-02 Splice Bushing:To connect fiber to probe$14OOISensors Software:OOISensors 32-bit operating softwareCall for Price
