Compact ODM98 integrating sphere

The UPK-50-L integrating sphere is one of Gigahertz-Optik’s compact size models with ODM98 coating. The 50 mm diameter integrating sphere with 10 mm diameter measurement port offers high light throughput required in light sensitive applications within the spectral range from 250 nm to 2500 nm. Its unique collar baffle design greatly avoids direct illumination of the detector port from the light input port in a conventional 90° port position sphere design. The baffle also makes it possible to operate up to 3 detectors or fiber light guide connectors on the sphere at the same time (positioned at 9, 12 and 3 o'clock). The detector ports provides an interface for direct mounting of Gigahertz-Optik’s PD-11, TD-11 and VL-11 type light detectors and UFC-11 type fiber connectors.


Gigahertz-Optik’s calibration laboratory offers traceable spectral radiant power sensitivity calibration in the wavelength range from 250 nm to 1800 nm. For special cases please contact our sales team.
