ISV SERIES INTEGRATING SPHERE
VISIBLE SOURCES
The ISV Integrating Sphere is a compact, reliable, easy
to operate system specifically designed for test and
calibration of detectors and sensor systems which
respond in the visible light spectrum such as
photometers, CCD cameras, radiometers, remote
sensing systems, and vision enhancement systems.
The ISV Integrating Sphere visible source incorporates
a 12" diameter integrating sphere with a 4" diameter exit
port. The PTFE interior sphere coating provides uniform
and lambertian luminance. Optional Barium Sulfate or
Gold coatings are also available.
Controller
The ISV Integrating Sphere utilizes closed loop control of
the detector/attenuator system to precisely set and
maintain the desired output level. A silicon detector
continuously monitors the output of the lamps and
provides feedback to the attenuator, providing very
stable and repeatable performance.
Control electronics and lamp power supplies are built
into a single 5.25" high, 19" rack mount unit. Operation
of the system is from the front panel keypad or via the
built in Ethernet and RS-232 computer interfaces (IEEE488 optional).
EOI Model ISV410
Illumination is provided by four tungsten halogen
lamps. The variable output lamp uses a closed loop
control sensor and output attenuator to provide
unprecedented ease of use and stability. Three fixed
output lamps are automatically turned on or off as
required to extend the illuminance range. All four
lamps are calibrated to the National Institute of
Standards and Technology (NIST) traceable color
temperature of 2950 ± 25 K.
The ISV Integrating Sphere provides the uniform
stimuli required for visible testing including Minimum
Resolvable Contrast, Uniformity, and MTF. EOI offers
a complete line of testing software to automate these
and other test procedures.
