6. 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. To find out more about optical coherence tomography and how Tornado Spectral can help you unlock the potential of OCT for non-destructive testing applications, download the application note.

7. 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.

8. 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.

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: 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.
