High-performance reference sources for electro-optical system testingMAIN BENEFITS
The ISV Integrating Sphere Sources series from HGH is engineered for laboratories and R&D centers seeking a stable, traceable light source for optical sensor calibration. Each system is built around a high-uniformity integrating sphere, delivering consistent luminance and radiance over time and across a wide spectral range.
ADJUSTABLE LUMINANCE
and radiance outputs with ultra-high stability
UNIFORM OUTPUT PORT
up to 4 inches (≥ 101.6 mm)
WIDE DYNAMIC RANGE
suitable for the most sensiive sensors
REAL-TIME MONITORING
with robust design for both lab and field use
MULTI-INTERFACE CONTROL
including touchscreen, Ethernet, RS232, and IEEE488
RADIOMETRIC AND COLOR TEMPERATURE CALIBRATION
traceable to international primary standars
Whether used for calibrating visible cameras, SWIR focal plane arrays, or radiometers, ISV sources deliver consistent, repeatable results even in challenging low-light testing conditions.
Integrating Sphere Sources designed for ease of use and precision
Intuitive interface and control
The ISV sources are operated through a modern and ergonomic interface. A color touchscreen panel provides direct access to all key settings, allowing users to adjust luminance or radiance values and switch easily between units. Color temperature and night levels are also displayed in real time.
Automated closed-loop control
Thanks to a closed-loop feedback mechanism, the ISV system regulates output levels via an iris attenuator, based on real-time optical readings. This technology ensures outstanding repeatability and ultra-stable radiance or luminance, even during extended testing sessions, while keeping the color temperature and the spectrum constent.
Built-in test equipment (BITE)
All systems come with built-in test tools for internal diagnostics and performance validation, enhancing reliability and user confidence during critical calibration tasks.
Radiometric calibration traceable to International Standards
Every ISV Integrating Sphere source is delivered with a certificate of calibration in luminance or radiance and in color temperature that is traceable to International Primary Standards. This guarantees the accuracy and reliability of your measurements, allowing your lab or production facility to maintain strict quality assurance and meet regulatory requirements.
