USB-LS-450 Ocean Optics

The USB-LS-450 is an integrated, multi-purpose LED light source module designed for use with either a USB4000-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 a Fiber Optic Oxygen Sensor system.

Features

*Simplified LED-spectrometer interface -- LED connects to spectrometer, which plugs 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 can conveniently store calibration temperature calibration coefficients and oxygen calibration coefficients.
*No external power requirements -- 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.
