    Spectroscopy: Back-illuminated CCDs enable advanced spectroscopy instrumentation

    Michael Case
    Jan. 18, 2018
    Cameras with exceptional detection capabilities can be designed around high QE, back-illuminated CCD sensors, combined with advanced imaging spectrographs.
    FIGURE 1. A typical spectroscopy system consists of a light source, optical fiber, spectrograph, and a CCD detector.

    Spectrometers: Spectroscopic calibration uses LEDs and nonlinear optimization

    Michael Case
    Feb. 1, 2016
    Accurate, repeatable wavelength and intensity information is possible for a spectrometer using an LED source and nonlinear optimization by taking into account variations in system...
    FIGURE 1. Nomarski-microscope images show the onset (left) and progression (right) of laser-induced damage within voids and pinholes in a conventional 193-nm mirror coating. These mirrors exhibit moderate and severe damage from laser exposure. In both instances, laser-induced damage started within microscopic voids in the coating. The severe damage at right occurred after 240,000 pulses at 225 mJ/cm2 at a 100-Hz repetition rate.

    193-nm coatings resist excimer-laser damage

    Michael Case
    April 1, 2004
    The best way to design and test coatings for use at 193 nm relies on two approaches: one for high pulse energy and low repetition rate, and the other for low pulse energy and ...
