  1. Introduction To Portable Multi-Platform Raman System For Fuel Analysis
    6/18/2019

    Raman spectroscopy is a non-invasive, highly sensitive technology that quantitatively probes and analyzes chemical compositions and structures without the need for sample preparation. In the past, this technology was not useful for plant-based and petroleum-based products due to their high levels of high level of fluorescence that can overwhelm Raman signals in all visible wavelengths. This application note introduces BaySpec’s transportable Agility™ product line featuring dispersive multi-wavelength Raman spectroscopy technology. Now liquid fuels’ measurements and analysis are simple tasks done in a few seconds, without contacting, or any preparation of the sample.

  2. Non-Destructive Red Wine Measurement With Dispersive 1064 nm Raman Spectroscopy
    6/18/2019

    Despite advances, it remains a struggle to extract useful Raman spectra from fluorescent and luminescent samples. This app note discusses a non-destructive red wine measurement with dispersive 1064 nm Raman spectroscopy to determine its composition and contamination levels.

  3. Using 1064 nm Dispersive Raman Systems For Analysis Of Petroleum Products
    6/18/2019

    Raman spectroscopy is a non-invasive, highly sensitive technology that quantitatively probes and analyzes chemical compositions and structures without the need for sample preparation. In the past, this technology was not useful for petroleum and petroleum-based products due to their high levels of high level of photoluminescence that can overwhelm Raman signals in all visible wavelengths. This issue is now resolved by BaySpec’s line of 1064 nm excitation dispersive Raman systems that offer maximum reduction in fluorescence interference.

  4. Using 1064 nm Dispersive Raman Systems In Biofuel And Plant Research
    6/18/2019

    In the past, raman spectroscopy was not useful for plant-based samples due to their high levels of photosynthetic pigments as the fluorescent backgrounds can overwhelm Raman signals in all visible wavelengths. This issue is resolved by BaySpec’s line of 1064 nm excitation dispersive Raman systems.

  5. How To Make A Tissue Raman Measurement At 1064 nm
    6/18/2019

    The combination of improved Raman technology and the technique’s molecular sensitivity have led to a rise in Raman usage for a variety of applications including pharmaceutical, biomedical, industrial, and forensics. There remains, however, a struggle to extract useful Raman spectra from fluorescent and luminescent samples. For those users who require longer wavelengths such as 1064 nm, the only available option has been FT-Raman. Now, BaySpec’s new dispersive 1064 nm Raman spectrometers offer users a turn-key solution that combines the speed, sensitivity, and rugged design of traditional dispersive Raman instruments with the fluorescence avoidance of traditional FT-Raman instruments.

  6. Speed Up Testing And Improve Quality Of Electronics PCBA And Integrated Circuit Design And Testing With The Use Of Infrared Technology
    6/17/2019

    As electronic circuit boards and components get smaller and more powerful, inherent heating becomes a concern. Infrared camera technology is helping save electronic design companies money through improved test times and better product design.

  7. Close Is Not Close Enough: Micropositioners’ Role In Nanopositioning
    6/13/2019

    This article examines how micropositioners affect movement and positioning capability, as well as overall task effectiveness, by creating --literally -- a solid foundation for work at the nanoscale.

  8. SWIR Imagery Improves Air Quality From Space
    6/12/2019

    Developed by MPB Communications Inc. the GHGSat’s microSat, nicknamed "Claire," celebrates its second year in space this June. Flying a Sensors Unlimited 640HSX InGaAs SWIR Camera, this micro satellite circles the Earth every 90 minutes collecting infrared images. 

  9. Using SWIR For Optical Coherence Tomography (OCT) High Resolution Imaging In Tissue
    6/12/2019

    By using the 1.05 µm central wavelength, instrumentation companies are now developing systems to image deeper through the retina into the blood vessel layer (called the choroid) to diagnose eye diseases and monitor treatment.

  10. Why HOT MWIR Might Be A Better Fit Than Uncooled LWIR
    6/10/2019

    While cooled mid-wave infrared (MWIR) cameras have long held a tactical advantage over uncooled longwave infrared (LWIR) cameras, they also have been more mechanically complex, larger, heavier, more power-hungry, and more costly than uncooled LWIR cameras.
