Integrating Spheres

Thorlabs offers both calibrated (NIST traceable) and uncalibrated integrating spheres. The calibrated integrating spheres have one port and can be used with free-space or fiber sources. They are compatible with all of our power meters that feature a C-Series connector. The uncalibrated integrating spheres have three or four ports. The ports can be used with a variety of available detectors and input adapters.
