Miniature spectrometers such as our Jaz modular sensing suite are especially suited to solar irradiance measurements, where portability and flexibility make the researcher’s job easier. Determination of absolute and relative solar irradiance is possible, as well as related applications such as measurement of upwelling and downwelling radiation. Read the rest of this entry »

During the last 15 years, over 450 exoplanets (planets outside our own Solar System) have been discovered. Due to the nature of the discovery techniques, most of these planets are large — more like Jupiter than Earth — and orbit close to their parent star. While a small number of smaller, rocky planets (Super Earths) have been found, the discovery of a true ‘exoearth’ in the habitable zone around its parent star is still beyond the capabilities of our technology. However, in preparation for such a discovery which is likely within the next decade or so, there is considerable interest in how to characterize such planets and their atmospheres.

An investigation was performed to determine the long-term stability of the T-300 probe in seawater, as well as a comparative analysis with a Ross pH electrode. Seawater was obtained locally from a Dunedin, FL marina, and the test was performed isothermally in an environmental chamber at 25°C. An Ocean Optics USB2000 spectrometer was used with a 200?m slit and grating #2 with no lens installed. Read the rest of this entry »

Broad UV-NIR spectral coverage can be achieved in a miniature spectrometer configured with our XR-1 Extended Range grating, which is responsive from 200-1050 nm. Our USB2000+ Spectrometer with an XR-1 grating maintains good optical resolution over the UV-NIR range, making it useful for applications such as measuring the relative output of a combination deuterium-halogen light source.

Goal
There was an interest in non-intrusively monitoring pH in tubes containing wet soil samples. This was significant for a number of reasons; this was the first time the reflective patches were to be tested in something other than a cuvette, on a curved surface rather, and this was also the first time an analyte solution was observed that contained sediment or turbidity.

A smart Oxygen Cuvette is developed by coating the inner surface of a cuvette with oxygen sensitive thin film material. The coating is glass like sol-gel based sensor that has an embedded ruthenium compound in the glass film. The fluorescence of the ruthenium is quenched depending on the oxygen level. Ocean Optics phase fluorometer, NeoFox is used to measure this rate of fluorescence quenching and computes it for the amount of oxygen present. Read the rest of this entry »
