Photonics Medical Application Notes

1. Advantages of Point Source Emitters: Application Note 4/30/2012

   A Point Source Emitter is similar to a standard LED, however, its well defined circular area (usually 25μm-200μm in diameter) makes it ideal in applications involving encoders, machine vision, medical fiber, and any other application where a precise beam of light is needed. This application note provides background information on Point Source Emitters, and highlights their advantages over standard LEDs.

2. Optical Coherence Tomography 9/26/2022

   Optical coherence tomography (OCT) is a noninvasive, high-resolution optical imaging technology that creates cross-sectional images from interference signals received from an object under investigation and a local reference.

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

4. 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

5. 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.
6. 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
7. 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.
8. 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.

9. Using Raman Spectroscopy To Detect Malignant Changes In Tissues 5/25/2012

   Accurate, rapid, and non-invasive detection and diagnosis of malignant disease in tissues is an important goal of biomedical research. Optical methods, such as diffuse reflectance, fluorescence spectroscopy, and Raman spectroscopy, have all been investigated as ways to attain this goal. Diffuse reflectance utilizes the absorption and scattering properties of tissues, particularly from cell nuclei and stroma.

10. OCT for Non-Destructive Testing 12/18/2012

    Optical Coherence Tomography (OCT) is an imaging method that scans light across a sample/object, and then processes and transforms the reflected light to create a depth profile of up to several mm. Tornado Spectral Systems has developed a nanophotonic spectrometer for use in this application space.
