This integrating sphere is machined from PTFE and is the ideal solution for the measurement of diffuse light. It has a diffuse reflectance of 99% between 400nm and 800nm, >98% between 300nm and 1800nm (UV-Vis-NIR region), and >92% between 250nm and 2500nm.
Great for characterizing light sources or for use in a radiometric calibrated setup.
