    4/5/2017

    The UV LED market is predicted to expand as UVB and UVC LEDs improve in response to growing demand from emerging UV disinfection markets. This article discusses the state of UV LED technology and its market, as well as choosing the best LED products for each application.

  2. Radiation-Resistant Optical Fiber Amplifiers For Satellite Communications
    3/31/2017

    This white paper presents and discusses 1.55 μm booster amplifiers and pre-amplifiers that are suitable for satellite to ground, inter-satellite links, and flexible photonic payloads.

  3. Testing All-Fiber Widely Tunable Thulium Lasers
    3/31/2017

    The broad emission spectrum of thulium fibers, which can extend from 1600 to 2200 nm, makes a thulium fiber laser an excellent choice for building widely tunable fiber lasers. This paper details Gooch & Housego's results testing an all-fiber thulium laser system that can be tuned to any wavelength between 1710 to 2110 nm, without using any moving mechanical parts.

  4. Which Industrial Cutting Method Is Right For You?
    3/28/2017

    Some applications require one specific type of cutting method and the other two methods are out of the question. This application note presents the process of each industrial cutting method, and comparisons between laser cutting, water jets, and mechanical cutting.

  5. Minimizing Trade-Offs Between Spectral Smoothing And Resolution
    3/28/2017

    Boxcar smoothing is a convenient way to smooth out noise in a spectrum, enabling peaks of interest to be more easily viewed, defined and characterized for properties like peak intensity, center wavelength, and FWHM (full width half maximum). It is a convenient complement to spectral averaging, particularly to minimize acquisition times, but must be used judiciously to avoid impacting the spectral resolution of the data acquired.

  6. Noise In Spectrometers: Part 2
    3/28/2017

    Noise is an undesirable signal that is completely lacking in information or structure, and potentially takes away from the desired signal’s quality and accuracy. Part one of this two-part series discussed the sources of noise from a spectrometer and its experimental methods. This second part of the series takes the information gleaned in part one and uses it to measure low concentrations of sports drinks in a pool, develop a calibration curve,  and determine the limit of detection for the spectrometer.

  7. Noise In Spectrometers: Part 1
    3/24/2017

    This application note is the first part in a series discussing the noise within spectroscopy systems used for ordinary applications, such as making sure the pool is clean after a large family gathering.

  8. Utilizing Silicon Photodiodes For Gamma Ray Detection
    3/21/2017

    First Sensor’s X100-7 is designed to target high volume gamma detection applications with reliable and cost-efficient packaging. Awareness has been raised in regard to risks from nuclear radiation, creating an additional demand for commercial and personal radiation detection devices.
