Integrating Sphere Components

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. The 819C (4 port spheres) and 819D (3 port) Series Integrating Spheres can be used 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 various 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.

Newport also carries an extensive list of 819M series accessories compatible with the 819C and 819D spheres.

Spectralon™ or Spectraflect™

The integrating sphere has either a Spectralon™ or Spectraflect™ coated sphere. The Spectraflect™ coating has an effective range from 300 nm to 2400 nm, with reflectivity of >97% at 600 nm. The unmatched environmental stability and high-performance of the Spectralon™ Integrating Spheres are derived from their rugged monolithic thermoplastic material and are superior to coated integrating spheres. In addition, their high damage threshold surface can be cleaned with distilled water. Hydrophobic, chemically inert and thermally stable to 350°C, Spectralon™ Spheres can be used in demanding environments, including underwater and high or low temperature processes. At the same time, reflectance exceeding 95% from 250–2500 nm, 98% from 310–2100 nm, and 99% from 400–1500 nm make them ideal for even the most demanding measurements from the ultraviolet to the near infrared.
For calibrated Integrating Sphere Detectors, see Integrating Sphere Detectors.

Flat Black Coating

Accessory products are available not only in either Spectralon™ or Spectraflect™ but also in Flat Black type coating in some cases. Flat Black type highly absorbs light and is used to imitate an open port, which does not have any reflection, but to reduce introduction of ambient light into the sphere.
