Irradiance Integrating Spheres for Spectrometers & Optical Fibers
Integrating spheres are available that connect to Ocean Optics spectrometers and optical fibers to measure the spectral output of LEDs, lasers and other light sources. Each sphere consists of diffusing material that provides a Lambertian surface for irradiance measurements. Various sample port sizes are available, and some models can be attached directly to the spectrometer.
