NEWPORT 819C-SF-6 6" INTEGRATING SPHERE 4 PORT SPECTRAFLECT

Some light scratching to outside of dome, function unaffected. Unit would normally include a Newport 2.5 inch port plug 819M-PP-SF-2.5 from the factory, but it isn't present on this unit.

The 819C-SF-6 Integrating Sphere is a 6 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.
