Stretched Design Specially for Side Emitting Fibers
Integrating sphere models UPK-30S60-L feature a unique stretched design specially made for the measurement of side emitting fibers up to 40mm long. Elongation of the ODM98 coated sphere from 30mm diameter to a length of 60mm eliminates the need for a large diameter sphere. Its unique collar baffle design avoids direct illumination of the detector by the side emitting fiber. The detector port 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 light guide connectors. The recommended useful wavelength range of the stretched integrating sphere is from 250 nm to 2500 nm. Gigahertz-Optik’s calibration laboratory offers traceable spectral radiant power sensitivity calibration in the wavelength range from 250 nm to 1800 nm.
The model UPK-30S60-TT is equipped with a test tube guide that prevents the side emitting light guide from contacting the internal integrating sphere coating. The test tube can be removed for cleaning.
