The 819C-GL-6 is a 6-inch diameter, 4-port integrating sphere with a diffuse gold coating optimized for high reflectance from 800 nm to 20 µm, achieving over 90% reflectance at 800 nm and over 94% at 1550 nm. The gold coating has a damage threshold four times greater than Spectralon. The sphere has 1.0-inch diameter ports at 0°, 90°, 180°, and the north pole. Built to accommodate 819M series accessories, it enables precise light measurement of divergent beams with signal attenuation and insulation from detector position errors.
The 819C-GL-6 is a 6 inch, gold coated, 4-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 90° is typically used for mounting a detector. The port at 180° is for the incoming collimated beam. The port at the North Pole location (top) is for fiber optic taping to monitor 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 0° port and the 90° 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.
