Integrating Spheres

Product Description:

The Instrumentation division of Gooch & Housego has manufactured integrating spheres for over 20 years. We offer spheres in a range of sizes, as well as a multitude of baffle and port configurations, to meet any source or input optic requirement. Sphere coatings for applications in the UV through IR wavelength ranges are available. We offer integrating spheres for:
