Newport 819C-IS-5.3 Integrating Sphere – 5.3 inch, PTFE based, 4-Port
The 819C-IS-5.3 Integrating Sphere is a 5.3 inch, PTFE based, 4-port integrating sphere. It replaces 819C-SL-5.3. The port at 180ยฐ used for beam input (direct or with fiber adapter). The diameter of the 0ยฐ port is 2.5 inch, but the sphere comes with a port plugย 819M-PP-2.5ย pre-mounted. The port at 90ยฐ is used for the detector (user selectable) and the port at the North Pole location (top) is for fiber optic taping to monitor wavelength. This setup is suitable for accurate, absolute value light power measurement of laser diodes. Your measurements will be insensitive to errors caused by detector positioning or problems associated with overfilling, or saturation, of the active area of the detector. In an integrating sphere, the detected flux is always a small fraction of the incident flux. All spheres include a baffle between the 90ยฐ and 0ยฐ ports, which prevents direct illumination from the light source to the detector port.
