The 819D-SF-4 Integrating Sphere is a 4 inch, Spectraflect coated, 3-port integrating sphere. Its damage threshold is 1.7 J/cm2. The port at 0° used for beam input (direct or with fiber adaptor). A 1.5 inch to 1 inch port frame reducer 819M-PFR-1.0-1.5B is premounted at the 0° port, which can be easily removed for experimental requirements. The port at 90° is used for the detector (user selectable) and the port at the North Pole location (top) is for fiber optic taping to monitor wavelength. All spheres include a baffle between the 90° and 0° ports, which prevents direct illumination from the light source to the detector port. Your measurements will be insensitive to errors caused by detector positioning or problems associated with overfilling, or saturation, of the active area of the detector. A baffle, positioned between the input port and the detector port prevents the detector from directly viewing the emitting aperture of the laser or the direct area of illumination. By adding Newports 819 Series port adapters and accessories, numerous integrating sphere configurations can be obtained.
