Integrating Spheres

Integrating spheres are optical components with a spherical cavity constructed of white reflective material for diffusing and depolarizing light. Thorlabs offers Ø100 mm modular spheres with user-configurable ports, Ø2" spheres with three or four ports, and calibrated spheres of various sizes with a single port. Free-space sources, fiber sources, and a variety of Thorlabs detectors are compatible with the integrating spheres.
