Integrating Sphere, 4-Port, 4 in. Diameter, Barium Sulfate. 1.5 in. Port Plug Included

The 819C-SF-4 Integrating Sphere is a 4 inch, Spectraflect coated, 4-port integrating sphere. Its damage threshold is 1.7 J/cm².  The port at 90° is used for the user selectable detector. The port at 180° is for the incoming collimated beam. 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. By adding Newport's 819M Series port adapters and accessories, numerous integrating sphere configurations can be obtained.  Shipped with a 1.5 inch port plug 819M-PP-SF-1.5 premounted at the 0° port.
