Newport 819S-IS-4 is a 4"-diamenter Integrating Sphere used for measurement of divergent light from laser diode sources. Their thin walls, only a few millimeters thick, make it possible to position the laser diode very close to the internal cavity of the sphere and thus collect 100 percent of the light emitted from the front facet of the device. 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.
