Abstract: A light bar for illuminating a surface that is substantially perpendicular to the light bar includes an elongated housing extending along an edge of the surface to be illuminated. The housing has a wall adjacent the surface to be illuminated, and at least portions of that wall are transparent. A series of light emitting diodes (LEDs) are mounted within the housing and spaced along the length of the housing for illuminating the surface, and a connector couples the LEDs to an electrical power source for energizing the LEDs to produce light that illuminates the surface.

Abstract: A method and device for cleaning at least an end face of an optical device retained within an optical connector using a cleaning fabric, comprises, alone or in combination, a) preventing the cleaning fabric from contacting the connector prior to contacting the end face of the optical device; b) a cleaning nose being made of a nose material having a hardness less than that of a material of the optical device with a flexural modulus greater than 2700 MPa and c) ensuring a constant tension on the fabric as it is circulated.

Abstract: The present invention is a method for calibrating power spectral data obtained with an interferometer based Fourier transform spectrometer which utilizes a laser based coherent radiant source as the metrology source. A radiant beam of predetermined wavelength from a neon lamp based noncoherent radiant source is directed in parallel with a radiant beam from the laser source into the interferometer to create a laser based interference pattern and a neon lamp based interference pattern. Distinct fringe counts are derived from the laser based interference pattern and the neon lamp based interference pattern. The wavelength of the laser source is determined based on a correlation between the known wavelength of the neon lamp based interference pattern and the determined fringe counts. The scale of the power spectral data is calibrated based on the determined wavelength of the laser source.
