We bring quality to light. External Optical Probes EOP-xxx and ISP 40 Product highlights Versions with different cosine correction and light throughput Flexible fiber optic cable to the spectroradiometer Special version with fixed fieldof-view of 5.7° Instrument Systems supplies a series of different optical probes for measuring irradiance and illuminance. They are also used for general coupling of light into the spectrometer. The optical probes differ primarily in the light throughput, degree of cosine correction and the spectral range. All optical probes in the EOP-xxx series include a diffuser for scattering incident light. The type of diffuser determines the overall quality of cosine correction and this in turn exerts an effect on light throughput. Almost perfect cosine correction can only be achieved with an integrating sphere. Instrument Systems therefore supplies the ISP 40 integrating sphere for universal light input from light sources. Adjusted optical probes are supplied for specific applications, such as measurements with defined fields-of-view or for measurements in the infrared range. The optical probes are connected to a spectroradiometer using either fiber bundles or thick-core fibers. The precise selection of the optical fiber and the fiber plug adapter depends on the available spectral range. light measurement

We bring quality to light. External Optical Probes supplied This table shows an overview of the available optical probes and provides a qualitative assessment of their cosine correction and light throughput. Model Spectral range With fiber bundle connector EOP-120 Universal, very flat design Weak light For extended light sources 5.7° field-ofview Cosine behavior of different EOPs With SMA fiber connector EOP-350 very good Solar irradiation Cosine correction Assuming that the light source is arranged normal to the detector surface, photometric fundamentals indicate that irradiance can only...

We bring quality to light. Good or very good cosine correction is necessary for analyzing extended light sources. However, this entails a loss in light throughput. The EOP-146 optical probe provides the best characteristics for this type of application. The EOP-140 optical probe is only suitable for applications requiring a high light throughput because the cosine correction is correspondingly low. The diagram shows technical drawing EOP-140 The diagram shows technical drawing EOP-146 The EOP-350 model with SMA fiber connector is supplied for special applications in the infrared range....
