The series includes three precisely calibrated spheres that measure powers from 20nW to 30W.
The IS-1 is a 25mm (1”) sphere that measures powers from 20nW–20mW for light sources from 0.35–1.1µm.
The 3A-IS is a 40mm (1.57”) sphere that measures powers from 1–3W for light sources from 350-1,100nm.
The IS-6 is a 135mm (5.3”) sphere with 4-ports. It measures both high and low power divergent beams, from 20µW to 30W, for light sources from 0.2-2.2µm
All three integrating spheres can measure beams with divergence up to 40°. Each is delivered as a calibrated unit with a photodiode detector. The IS-6 can be purchased with no detectors for use in the user’s measurement setup or as a uniform light source.
