Integrating Spheres

The integrating spheres available from ISI are cost effective solutions for many applications including laser power, flux, reflectance and radiance measurements.

The unique manufacture method provides excellent performance levels for a fraction of the cost of selected laser sintering options. We offer unprecedented levels of user customisation. The input and output ports are designed to take fibre adapters when in use or closed using the provided port plugs.

The spheres are manufacturing via 3D printing using sintered nylon.

The high reflectivity is ensured by using Avian-B reflectance coating.
