IRVINE, Calif., April 29, 2011 — Newport Corp. has announced the newly enhanced calibrated integrating sphere detectors. Suitable for measurement of output light power of high-power light sources, the spheres optimize the measurement geometry for laser beams and other light sources, whether collimated or divergent.
The new series includes Model 819C (collimated) and Model 819D (divergent); both deliver good NIST-traceable calibration uncertainties of <3% for most measurement ranges specified.
The calibrated integrating sphere models with a silicon detector operate from 400 to 1100 nm, and the ones with an indium gallium arsenide detector cover the spectral range from approximately 800 to 1650 nm. To accommodate various power range requirements, the calibrated integrating spheres are available in 2-, 3.3- and 5.3-in. diameters.
The new design includes a robust port frame plus a variety of attachments and accessories to provide greater configuration flexibility. All sizes of the spheres include an SMA fiber optic connector on the north pole as a standard feature, allowing a small amount of light pickoff for wavelength measurement or any further analysis, without affecting the overall system calibration.
