Near-Infrared (NIR) Detectors

Opto Diode presents the new series of near-infrared (NIR) detectors that are designed specifically for back-facet laser monitoring applications that require improved performance in the near-infrared (NIR) spectrum from 700 nm to 1100 nm. These new NXIR photodiodes maximize measurement repeatability, are highly reliable, and offer a low cost solution for NIR wavebands. The NXIR-RF36 and NXIR-RF74 are ideal for integration with semiconductor lasers such as the Fabry-Perot (FP), distributed feedback (DFB) lasers, and vertical-cavity surface-emitting lasers (VCSELs). The NXIR-5W can be used in biological, dental, and medical equipment, as well as in fluid dynamics, manufacturing, and military applications.

  • Keeping LEDs Cool Gets More Manageable Through Simulation

    LED light sources are constantly replacing incandescent lighting in general lighting applications due to their longer lifespan, high luminosity, and "green" characteristics. One of the drawbacks of LEDs is that their temperature must be carefully regulated. Heat removal is critical in LEDs because, unlike conventional light sources, LEDs need to operate at the lowest possible temperature. This article introduces a study that sets out to design to most efficient heat sink for an LED lighting device through the use of simulation.

  • Cavity-Based Mid-IR Fiber Gas Laser Pumped By A Diode Laser

    Lasers for mid-infrared (IR) applications have gone through rapid development with many competing technologies and techniques. One technique is to use traditional gas lasers with standard gain fibers. This method, however, is limited in its interaction length, and the system is bulky and inflexible as a whole. This application note demonstrates another technique that uses a mid-IR fiber gas laser utilizing feedback in an optical cavity. The laser method works through the use of acetylene gas in a high-performance silica hollow-core fiber. It is able to lase in either continuous wave or synchronously pumped when pumped by telecom-wavelength diode lasers.

  • The Meaning And Measure Of Vertical Resolution In Surface Metrology

    Understanding performance specifications is the first step in the process of selecting an instrument or technology for areal surface topography measurements. One of the more frequently cited parameters is known as “vertical resolution,” which is defined as the smallest surface height variation that can be detected. As a result of a review of instrument brochures, technical articles, and international standards, it was found that there is not a consensus regarding the meaning of "vertical resolution" and its numerical specification, which leads to a lot of confusion in the industry. It is important to re-evaluate the use of the term “vertical resolution” and identify a better way to characterize other instrument performance specifications.
