Fiber Optic Integrating Sphere: FOIS-1
This fiber optic integrating sphere is ideal for emission experiments like spectral property measurement of LEDS and other light sources. It does this by accepting light energy from 200-2500 nm through a 9.5 mm input port, and then funneling it to an optical fiber. The FOIS-1 measures just 56.8 mm x 62.4 mm x 38.1 mm and weighs only 240 g. It consists of a 1.5" Spectralon sphere, the aforementioned input port, and an SMA connector for spectrometer coupling.
The interior of the FOIS-1 Fiber Optic Integrating Sphere is made from Spectralon, a white diffusing material that provides a highly Lambertian reflecting surface. This integrating sphere is easy to operate. The user simply connects an optical fiber (the read fiber) from the FOIS-1's SMA 905-terminated output port to the SMA termination of the spectrometer. The emission source is then inserted into the 0.375" input port of the FOIS-1. The setup can also be configured so that the light energy from the emission source can enter the input port.
