Integrating spheres from Ophir available
A series of Ophir integrating spheres includes the IS-1 25 mm sphere that measures powers from 20 nW to 20 mW for light sources from 0.35 to 1.1 μm. The 3A-IS 40 mm sphere measures 1 to 3 W from 350 to 1100 nm. The IS-6 135 mm sphere with four ports measures high- and low-power divergent beams, from 20 μW to 30 W and from 0.2 to 2.2 μm.
