Newport 819-OPT-IR Integrating Sphere

The Newport 819 Integrating Spheres are useful 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. In an integrating sphere the detected flux is always a small fraction of the incident flux. This attenuation, caused by light reflecting many times before reaching the detector, makes the integrating sphere ideal for measurement of output light power of high-power lasers.
