1 External Optical Probes EOP-xxx and ISP 40 Two Global Leaders. One Complete Solution.

2 Our story Two Global Leaders. One Complete Solution. Konica Minolta Sensing Americas provides advanced optical technology that precisely measures the elements of color and light. Their products have become a staple in research and manufacturing environments, helping organizations to meet product quality and operational goals with less waste, time, and effort. This commitment to creating value for customers is the core principle behind the Konica Minolta brand, and has led them to develop the world s first portable spectrophotometer and the first light meter used on board a spacecraft (Apollo 8). It s also the driving force behind the high level of quality and precision built into each of their products. These are some of the reasons why Konica Minolta is regarded as the technological leader in color and light measurement solutions today. Based in Germany, Instrument Systems develops and produces high-quality optical test and measurement instruments for a broad spectrum of applications. Their extensive product range includes spectrometers, imaging photometers and colorimeters, goniophotometers, integrating spheres, and turnkey system solutions. Instrument Systems is dedicated to working with standardization committees and associations such as ICDM and CIE. They also cooperate with leading national metrology institutes. Now, these two experts have combined their knowledge and tools together to offer the complete solution for the most accurate measurement of light and color available in the market today.

3 Product Highlights Versions with different cosine correction and light throughput Flexible fiber optic cable to the spectroradiometer Special version with fixed fieldofview of 5.7 Cosine Correction Assuming that the light source is arranged normal to the detector surface, photometric fundamentals indicate that irradiance can only be correctly determined for extended sources if the signal sensitivity of the detector changes with the cosine of the angle of incidence. E = E 0 cos(α) 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. E : Irradiance measured at the incident angle E 0 : Irradiance at normal incidence α : Angle between the incident light beam and the detector normal As a general rule, the better the cosine correction, the lower the light throughput. The photometric integral was always measured for the cosine behavior of different optical probes shown below. This means that the curves displayed only apply to the visual range. The table shows the acceptance angle as a rule of thumb for individual EOPs. The assumption is that the deviation from the ideal cosine behavior must not be greater than 5%. The ~ sign is due to minor deviations in the symmetry of the optical probes. Acceptance angle for deviation < 5% EOP-140 +/-3 5 cm EOP-120 +/-6 11 cm EOP-146 ~ +/ cm ISP ~ +/ cm Largest dimension of an object at a distance of 1 meter 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.

4 Throughput The same OFG-465 fiber bundle was used to measure the throughput of all optical probes for the wide spectral range and the halogen lamp (spectral range 300 nm nm). ISP has the lowest throughput in the entire measured wavelength range. The values were therefore standardized on 1. Higher values therefore entail higher throughput. EOP-146 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. 300 to 380 nm 380 to 1000 nm 1000 to 1650 nm 1650 to 2100 nm ISP ISP EOP EOP EOP The Range of Models EOP-120 and EOP-121 For general applications we recommend the optical probes from the EOP-120 and EOP-121 series (the latter with fiber bundle connector on the side) since these offer the best compromise between average cosine correction and good light throughput. The diagram shows technical drawing EOP-146 ISP 40 Integrating spheres offer ideal cosine correction together with broad spectral range. Instrument Systems has developed the ISP 40 with 44 mm internal diameter to meet this requirement. The integrating spheres are either coated with Spectralon (ISP40-101) or barium sulfate (ISP40-102). The ISP 40 can also be used for universal light input and for lasers. The rectangular shape provides easy handling and the internal cavity is naturally spherical in shape.

5 EOP-140 The EOP-140 optical probe is only suitable for applications requiring a high light throughput because the cosine correction is correspondingly low. EOP-350 The EOP-350 model with SMA fiber connector is supplied for special applications in the infrared range. The diagram shows technical drawing EOP-140 The diagram shows technical drawing EOP-350 EOP-542 The EOP-542 model is supplied for measurements with defined fieldof-view of 5.7. This probe is mainly used to analyze direct sunlight. The diagram shows technical drawing EOP-542
