Advanced Spectral Shaping Technology from Ocean Optics

Signal-balancing technique is scaleable to large-volume spectrometer
Dunedin, Florida (June 3, 2010) – Ocean Optics, the industry leader in miniature photonics, has developed a proprietary light shaping technique for its spectrometers that balances and smoothes the uneven spectral emission from UV-Vis light sources used for spectroscopy applications. As a result, users can measure light more evenly across a broader spectral region and thus improve signal-to-noise performance. The technique is especially useful for spectral absorbance applications where strong absorbing bands coexist with bands of low signal in the unbalanced spectrum. This low signal level limits the maximum measurable optical density.

 

Ocean Optics’ spectral shaping technology is applied to a miniature spectrometer optical design to balance the uneven spectral emission from UV-Vis light sources used for spectroscopy applications.

Traditionally, the spiky spectral output of a lamp – i.e., distinguished by sharp and narrow peaks – of light sources used in spectroscopy is handled at the source itself. But methods such as using mechanical fixtures or optical filters at the light source can result in greater light loss and may be too expensive or impractical, especially when instrument to instrument uniformity is desired. The patented and proprietary Ocean Optics spectral shaping technique modifies the light internal to the spectrometer so that specific wavelengths or wavelength bands are selectively attenuated. This makes it easier to optimize the spectrometer setup in concert with the light source.

The Ocean Optics OEM Engineering Team is now able to apply this novel spectral shaping technique to a variety of OEM applications. This dedicated engineering group provides expert support to help OEM customers bring products to market faster and better optimized to commercial requirements. The team offers complete system design capability for OEMs from supply of fiber assemblies and light sources to sensor coatings and sample holders. The company is ISO 9001:2008 certified and can support both integrated system and sub-system manufacturing needs. Additional information is available at www.OceanOEM.com.
