  • Glossary of Terms
    . Bus Bar. A bus bar is a thick strip of silver, chrome-nickel-gold, or silver epoxy that conducts electricity. Bus bars are used to carry very large currents, or to distribute current to multiple devices within switchgear or equipment. Ceramic Glass. This glass is mechanically very strong material
  • Fast Response Optical Sensors Prove Invaluable in Demanding Gaging Applications
    configurations provide sub-micron resolution and/or a large measurement range. MTI's Fotonic TM sensors provide accurate measurements on almost any type of surface or material including metallic, plastic, glass and ceramics. They can also operate in water or oil, however, a slight sensitivity change occurs
  • Design, Calibration and Performance of Microtops II Hand-Held Ozonometer.
    is a quartz prism in the Dobson and a. diffraction grating in the Brewer. Filter Ozonometers. Filter-based ozonometers are much smaller and less costly than spectrometer instru ments. Their. performance, however, is less than desirable due in large part to the wider spectral passband of filters. Optical
  • Phase Conjugate Laser Optics - Preface
    . their operating conditions, and they provide maximum brightness to the user for. a large diversity of scientific or industrial applications. The critical issue of this very. attractive approach is to identify the most efficient media and nonlinear mechanisms. that operate at the required wavelengths
  • Novel Interferometer Enables Challenging Measurements
    involving measurement. of thin, transparent optics, including inspection of large glass substrates for flat panel displays. In some cases it. also enables measurement of the individual surfaces of multi-component optical systems, prisms, etc. Remote Cavity Measurements. The interferometric "cavity
  • Fiber Optics: Theory and Applications
    the reflecting surface is not parallel to the fiber. depends on the f/number or numerical aperture (see. axis. Collimated light entering tapered fibers at the large. Figure 1 2). It is calculated from the formula. end, on the other hand, becomes decollimated, and if the. angle of incidence exceeds

    -. mance. The equations are as follows: X2. a. D = 2L. D = (X1 + X2)cos(ß ­ ). Where D equals the offset. Traditionally, industry uses beam. X1. deviation as the key measure of ac-. curacy. When a retroreflector is fully. illuminated by a large parallel beam,. it returns six subaperture beams. Accuracy
  • Michelson Interferometer Whitepaper
    spectrometer with similar resolution, the FTIR has much higher brightness which results in much shorter observation time. Imaging spectrometers (field widening). One of the most powerful features of a Michelson spectrometer is the ability to maintain a constant optical path difference over a large
