Abstract: An integrating sphere includes twelve pentagonal spherical shells and twenty hexagonal spherical shells. The hexagonal spherical shell includes a first circular spherical shell having a first diameter and six first auxiliary spherical shells formed by cutting the first circular spherical shell. The pentagonal spherical shell includes a first circular spherical shell having the first diameter and five second auxiliary spherical shell formed by cutting a second circular spherical shell having a second diameter.
