Improved Spectrometer for Long Pathlength Absorbance

Technology Benefits

Allows for measurement of extremely dilute samplesAdjustable path length also allows for measurement of high concentration samplesDesign uses standard optics and off-the-shelf spectrometer components The dove prism configuration allows for liquid flow-through spectroscopy and evanescent wavemeasurements of condensed phase samples

Detailed Technology Description

This technology improves the optical configuration of spectrometers for long path length absorbancemeasurements for gases and condensed phases. Developed by Drs. Aldstadt & Geissinger as animproved approach to absorbance spectroscopy, this technology uses a compact optical cavity with arotating mirror to control the beam path length. Based on this technology a prototype was constructedand successfully demonstrated the proof of concept.
