The 819D-GL-4 is a 4 inch, gold coated, 3-port integrating sphere. The gold coated spheres are optimized to provide high level of diffuse reflectance from 800 nm to 20 um (>90% at 800 nm, >94% at 1550 nm) . Its damage threshold is 19.7 J/cm2, which is 4 times greater than Spectralon. The port at 0° is typically used for beam input. The port at 90° is typically used for a detector, while the port at the North Pole location (top) is for fiber optic taping to monitor the wavelength. The sphere is suitable for accurate, absolute value light power measurement of laser diodes and other diverging beam. The measurements will be insensitive to errors caused by detector positioning or problems associated with overfilling, or saturation, of the active area of the detector. 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. By adding various port adapters and accessories, numerous integrating sphere configurations can be obtained.

819D-GL-4是一个4英寸，镀金，3端口积分球。经过优化的金涂层球提供了800 nm到20um的高水平漫反射(在800 nm时>90%，在1550 nm时>94%)。其损伤阈值为19.7 J/cm2，是Spectralon的4倍。港口在0°通常用于光束输入。港在90°通常用于一个检测器,而港口在北极位置(上)是光纤录制监控波长。适用于激光二极管及其它发散光束的精确、绝对值光功率测量。测量结果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。位于输入端口和检测器端口之间的挡板阻止检测器直接查看激光器的发射孔径或光照的直接区域。通过添加各种端口适配器和附件，可以获得大量的集成球体配置。
