Photonics Medical Application Notes

  1. Pre-, Intra-, And Postoperative Use Of Dynamic Infrared Thermography (DIRT) Provides Valuable Information On Skin Perfusion In Perforator Flaps Used In Reconstructive Surgery 2/17/2012

    A study of dynamic infrared thermography (DIRT) in all three phases of perforator flap surgery.

  2. NDT In Composite Materials With Flash, Transient, And Lockin Thermography 2/16/2012

    Composites are now used in everything from aircraft to prosthetics. By Markus Tarin and Ralph Rotolante

  3. Application Note: High-Speed Spectroscopy 9/15/2008
    Optical spectroscopy is an almost universal technique for monitoring substances or processes. There are many varieties of spectroscopic techniques for various applications. Some of these applications (combustion research, for example) require very quick measurement times, especially if the process of interest is very fast. By IMRA America, Inc.
  4. UV Measurement Of Sunglasses Using A Back-Thinned CCD Spectrometer 1/22/2013

    In assisting thousands of customers over the years, we’ve discovered that everyone has a slightly different idea of what constitutes ultraviolet light. For some, it’s the light just beyond human vision that some animals can see (300-400 nm). For others, it’s ionizing radiation that propagates only in a vacuum, below 120 nm.  What we can all agree on, however, is that UV light is not good for our eyes, and that a proper pair of sunglasses needs to block these harmful rays.

  5. Measuring The Opacity Of Plastic Tubing With VIS-NIR Transmission Spectroscopy 1/22/2013

    Plastic tubing is available in a variety of opacities ranging from clear to translucent. The transparency of plastic tubing is varied for a number of reasons including providing contrast for visual monitoring of fluid flow, decreasing exposure to ambient light and making the tubing more distinct for machine vision technology. In this application note, VIS-NIR transmission spectroscopy is used to assess the amount of frosting applied to plastic tubing to determine if the tubing meets the required opacity level.

  6. Coat Of Many Colors: Cases In Equine Thermal Imaging 2/17/2012

    Infrared cameras have improved, procedures have been standardized, and veterinarians have become familiar with interpretation of the images. By Joanna L. Robson, DVM

  7. Lenses For Diagnostics 10/13/2023

    Medical diagnostics rely heavily on imaging technologies that allow physicians to examine and assess a patient's body structures and functions in great detail.

  8. Solutions For Critical Medical Applications 12/20/2010
    Raytheon ELCAN Optical Technologies is well known for its precise optical solutions for critical military applications. By ELCAN Optical Technologies
  9. Application Note: Detection Of Hydrocarbon Radicals During Plasma Etching 4/16/2010

    Optical emission spectroscopy is used to study and monitor the plasma etching of hydrogenated amorphous carbon (a-C:H) thin films. T.A.R. Hansen and R. Engeln, Eindhoven University of Technology

  10. Application Note: Magnetic Field Sensitivity 8/18/2008
    SPM detectors are insensitive to magnetic fields unlike PMTs, which are very sensitive to even weak magnetic fields (<0.1T).
