An integrating sphere, also known as a photometric or luminous flux sphere, is a hollow cavity coated with a white diffuse reflective material. One or more ports are opened on the sphere wall, serving as light entry or detector ports. The inner surface is coated with highly diffuse materials such as PTFE foam or gold. These are mixed with adhesive and sprayed evenly onto the inner wall. Magnesium oxide coatings provide over 99% reflectance in the visible spectrum, enabling light to undergo multiple reflections inside the sphere and form a uniform irradiance distribution.

The UIP series integrating spheres are made from imported PTFE powder, sintered and foamed at high temperature, offering high reflectivity, excellent stability, and resistance to heat and humidity. They are resistant to oxidation and yellowing, making them easy to preserve. The spheres are compatible with the SM05 (0.535"-40) thread standard and standard 30 mm cage systems, making them easy to integrate into existing setups. They also support mounting via an M4 threaded hole at the base.
