4-Port Integrating Sphere, 3.3 in., PTFE, Inc 0-Deg 1.5 in. Plug

The 819C-SL-3.3 Integrating Sphere is a 3.3 inch, Spectralon coated, 4-port integrating sphere. Its damage threshold is 5.0 J/cm². A 1.5 inch port plug is included so that the 0° port is always plugged to the diffuse beam from opposite port. 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 819 Series port adapters and accessories, numerous integrating sphere configurations can be obtained.
