To measure luminous flux, color and spectral distribution of
large-area LED solid-state and traditional-type light sources, a large-diameter
integrating sphere typically is used.
Gigahertz-Optik Inc.’s ISD family of
integrating spheres is designed for use with the BTS256-LED tester. The ISD-100HF-V01
1000-mm-diameter integrating sphere is coated with the proprietary ODP97 white diffuse
barium sulfate. A bayonet mount on the detection port enables attachment of the
BTS256-LED tester. The sphere is designed for 4-pi geometry measurements of omnidirectional
light sources. The hinge frame stand allows one hemisphere to open/close for mounting
of the test LED or lamp source in the center of the sphere. A telescoping sample
holder supports positioning and electrical connection of the test light source in
the sphere center. An auxiliary port is included.
