The OL IS-670-LED consists of a 6-inch diameter, PTFE coated, high reflectance integrating sphere. It is mounted in a convenient, rugged stand for tabletop or laboratory benchtop use, eliminating the need for mounting rods or fixtures. The sphere has a 90° entrance port to exit port configuration and includes a SMA connector for connection of the auxiliary lamp incorporated into the OL 770-LED High-speed LED Test and Measurement System via an optical fiber.
The OL IS-670-LED yields spectral reflectance properties > 99% in the 300 nm to 1700 nm wavelength range. A coated internal baffle in front of the exit port prevents non-integrated light from exiting the sphere. The exit port of the sphere is coupled to the OL 770-LED via a fiber optic cable. A wide range of off the shelf LED holders are available, as well as custom LED holders for specific device configurations.
The OL IS-670-LED provides an accurate means of measuring the Total Spectral Luminous Flux and Total Radiant Flux of “forward-looking” LEDs. The OL IS-670-LED Integrating Sphere is designed specifically for use with the OL 770-LED to provide accurate measurements of many properties of light emitting diodes, and permits the user to make color measurements in accordance to recommendations by NIST and CIE Publication 127.
