Photonics Medical Application Notes

  1. 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).
  2. Application Note: 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
  3. Technical Note: High-Precision Micromachining 9/16/2008
    Laser micromachining is a large and rapidly-growing application area for pulsed lasers. In fact, the general application area of materials processing forms the largest single application market for all lasers sold. Microelectronics in particular is one of the largest industry sectors that uses laser micromachining for a variety of applications including mask repair, chip repair, linkblowing, wafer processing, via-hole drilling and others. Pulsed lasers that are widely used include excimer lasers and Qswitched solid-state lasers such as Nd:YAG and Vanadate systems. 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.

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

  6. 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.

  7. 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

  8. Application Note: Scintillator Readout With SPM 8/18/2008
    A large number of radiation detection applications utilize scintillation crystals to convert gammaor X-rays into a burst of optical photons that can then be measured with a suitable photodetector. Depending on the scintillator type and the application, the photodetector could be a PMT, PIN diode or an APD. The SPM is considered to be a viable alternative to these options, giving performance comparable with a PMT in the small, rugged, low voltage format of a PIN or APD.
  9. Application Note: Nonlinear Microscopy 9/16/2008
    Ultrafast lasers have revolutionized the field of microscopy by enabling new types of nonlinear microscopy techniques. Femtosecond pulse lasers provide the combination of high peak power (1-100 kW) and low average power (10-1000mW) which is ideal for utilizing nonlinear optical processes in scanning laser microscopy (LSM). Here, we describe the two main varieties of nonlinear microscopy: two-photon microscopy, and third-harmonic generation (THG) microscopy. And we show images using these techniques with various types of modelocked fiber lasers. By IMRA America, Inc.
  10. 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.
