  • Infrared Laser Marking Application
    Infrared (1064 nm) wavelength is arguably the most versatile of the marking wavelengths. IR lasers are capable of marking a wide variety of materials but are more commonly used on metals. A few of the best application materials include metals, plastics, and other materials.
  • Infrared Viewer Frequently Asked Questions
    Near-IR viewers are ideal for applications involving the alignment of infrared laser beams or of optical components in near-IR systems. Forensics & art restoration Substances have different transmission and reflection properties when viewed under near-infrared illumination as compared to visible
  • Phase Conjugate Laser Optics - Preface
    Since the discovery of the laser in the 1960s, a great amount. of research activity has led to an impressive increase of the overall. performances of the sources emitting in the visible or in the infrared. spectral regions. The most significant achievements for solid-state. lasers in the last 10
  • The Thermal Diffusivity of Dentin Using Infrared Thermography (.pdf)
    The thermal diffusivity is one of the most important parameters when heat conduction is studied. The goal of this study is to obtain the thermal diffusivity of human teeth dentin after Er,Cr:YSGG laser irradiation using infrared thermography. Twenty one dentin slabs with 2 mm thickness were
  • An Improved Wire Grid Polarizer For Thermal Infrared Applications
    and have a contrast ratio better than 40 dB. Transmission and reflectance measurements were made using a Fourier Transform Infrared (FTIR) spectrometer with instrument accuracy verified using silicon and germanium reference standards. Results were compared to RCWA modeling of the wire grid. polarizer (WGP
  • Infrared Sensor Graphic Interface PVC Sheet Material
    The WaferSight wafer-flatness tool performs high-resolution and high-throughput mapping of wafer shape, flatness, and thickness variations. Based on proprietary optical laser interferometry, the in-line metrology system is available for 300- and advanced 200-mm wafer processing. Its subnanometer
  • How a helium neon gas laser works
    The Helium Neon laser is one of the most economical and commonly used gas lasers on the market. The. laser is typically designed to operate in the red at 632.8nm, although many users find it beneficial in the. green at 543.5nm, yellow at 594.1nm, orange at 611.9nm, and in the infrared at 1523
  • Laser Welding Creates Potential for Small Parts Applications
    as the energy source is a process used to achieve a balance between the process of thermal fusion and metallurgical effects. Functionally, the laser generates infrared or visible light (usually with the use of Nd-YAG lasers or frequency-doubled "green" lasers for reflective metals) which
