LED Analyzer UMBB500HFBTS256LED Gigahertz-Optik

20 inch / 500 mm diameter integrating sphere set-up in 4∏ geometry for measurements of all-directional bulb type light sources with components from Gigahertz-Optik UM integrating spheres series. The hinge frame stand allows one hemisphere to open for mount and removal of the device under test in the centre of the sphere. The UMSH-AP500 all-purpose sample holder supports positioning and electrical connection of the device under test in the sphere center position.
