The 819D-IS-5.3 Integrating Sphere is our new 5.3 inch, PTFE based, 4-port integrating sphere, replacing the 3-port 819D-SL-5.3. Its damage threshold is 5.0 J/cm2. The diameter of the 0° port is 2.5 inch, but the sphere comes with a 1 inch port frame reducer pre-mounted. The 180° port comes with a 1 inch port plug pre-mounted, to simulate the existing 819D-SL-5.3. 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. All spheres include a baffle between the 0° and 90° ports, which prevents direct illumination from the light source to the detector port.

819D-IS-5.3集成球体是我们新的5.3英寸聚四氟乙烯为基础的4端口集成球体，取代了3端口819D-SL-5.3。其损伤阈值为5.0 J/cm2。0°端口的直径是2.5英寸,但球有一个1英寸端口减速器pre-mounted帧。180°港口有一个1英寸港口插头pre-mounted,模拟现有的819 d - sl - 5.3。在北极位置(顶部)的端口是用于光纤磁带监测波长。该装置适用于激光二极管的精确、绝对值光功率测量。您的测量将对探测器定位引起的误差不敏感，或与探测器活动区域的充盈或饱和有关的问题。所有领域包括0°、90°港口之间的挡板,防止直接照明从光源到检测器端口。
