ISP 2000
Integrating Sphere for measuring
radiant power and luminous flux
Product highlights
Measurement of total radiant
power and luminous flux of LED
modules, lamps and luminaires
Robust and universal sample
stage for many different
luminaires and SSL products
Lamp post for measuring light
sources in an upright or
suspended configuration
600 mm external measurement
port for launching light radiation
from outside
Auxiliary lamp to compensate
for self-absorption
The ISP 2000 is the most recent and largest member (1.9 m diameter) of the
well-established family of premium integrating spheres produced by
Instrument Systems. It incorporates all the unique capabilities that brought
success to its smaller peers. These characteristics are particularly effective
for testing LED modules, Solid State Lighting (SSL) products, and
conventional lamps and luminaires. The ISP 2000 is equipped with an
auxiliary lamp to compensate for self-absorption, a temperature sensor to
monitor the thermal conditions of the interior, and a detector port with a
fiber adapter to link the sphere with all spectroradiometers from Instrument
Systems. The company offers a complete package of calibration
accessories for the ISP 2000.
The ISP 2000 can be used to carry out measurements at 4π and 2π
geometry. The maximum sample size is 600 mm x 300 mm x 300 mm in the
center and the diameter of the external port is 600 mm. A lamp post is
available mounting the test specimen inside the sphere. It accommodates
optional adapters for all standard lamp sockets. A sample stage can be
used instead of the lamp post for mounting non-standard sample sizes, for
example complete luminaires and LED modules. This stage provides a
footprint of 200 mm x 150 mm and 16-pole connectors for the power supply
of the sample or for controlling purposes. A robust rail-mounted slide
mechanism delivers light-tight closure of the ISP 2000 and permits the
sphere to be opened easily for quick access to the interior.
