The new 819M Series Integrating Spheres are configured to optimize your measurement geometry for laser beams and other light sources whether collimated or divergent. These integrating spheres are offered in sizes ranging from 2” to 6” in diameter to accommodate most laser power range requirements. They are designed to provide greater configuration flexibility than ever before, including a new robust port frame design, compatible with many attachments and accessories including detectors covering the spectral range of 250 nm to 1800 nm. The spheres may be ordered with either of two types of diffuse reflectance material; Spectralon™ polymer lining or Spectraflect™ coating.
In an integrating sphere the detected flux is always a small fraction of the incident flux. This attenuation, caused by light reflecting many times before reaching the detector, makes the integrating sphere ideal for measurement of output light power of high-power light sources.
