  9. Understanding Edge Filters For Raman Spectroscopy
    5/8/2017

    Since the excitation source laser intensity is often six to eight orders of magnitude greater than the Raman scattered signal, edge pass filters are required to block the wavelength of the scattered laser beam while transmitting the wavelength shifted Raman scattered signal.

  10. Faster, Smaller Delay Lines Drive OCT Applications Further
    5/5/2017

    Optical coherence tomography (OCT) can be used in many medical applications including displaying real-time details of eye diseases, detecting skin cancer, or monitoring heart surgery. The OCT market is set to grow even further over the next few years as the efficiency and effectiveness of imaging improves.
