1 LEDGON 100 Goniophotometer 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 Accurate determination of the luminous intensity distribution and luminous flux at LEDs and small LED modules Angular-resolved analysis of spectral and colorimetric quantities Type C configuration with motorized phi and theta axis Compatible with all spectrometers manufactured by Instrument Systems Data export in IES and EULUMDAT format The Goniometer Unit The fixed goniometer unit allows the test specimen to be rotated through two axes: the phi and the theta axis. The phi axis permits the specimen to be rotated through a full 360 in the mechanical axis of the test specimen, while the theta axis can be moved perpendicular to this in an angular range of +/ The angular accuracy is 1 for the phi axis and 0.1 for the theta axis. The compact LEDGON Goniophotometer was specially developed for analysis of angle-dependent spatial radiation patterns from individual LEDs and small LED modules. The entire hemisphere can be measured in the forward direction of the LED. The angular resolution of 0.1 means that exact measured values can be obtained even for narrow-angled LEDs with a high level of reproducibility. Combined with a spectroradiometer from Instrument Systems, all spectral parameters, for example color coordinates or color temperature can be measured as a function of angle. Particularly in the case of white LEDs, these parameters can undergo significant change depending on the observation angle. Knowledge of this characteristic property is extremely important for using white LEDs in illumination technology. Equipment Setup: Light-Tight Without Dark Room Goniometer unit The unit comprises a flat optical bench and a goniometer unit with two angular axes that is mounted at one end of the bench. One of the rotation stages has a hollow shaft where an LED test socket (any socket except LED-850) from Instrument Systems can be mounted. An optical probe is positioned at the other end of the optical bench allowing the distance to the LED to be set at between 5 and 50 cm. Two baffles can be variably positioned at any point to eliminate stray light. LEDGON connected to spectrometer Solid angle definition for phi and theta The entire setup is located in a light-tight enclosure with a folding lid which eliminates the need for a dark room. If larger measuring distances are required, an opening in the side wall of the LEDGON 100 also allows light to be measured from outside.

4 Options and Accessories An optional sample table (LEDGON-130) also permits measurement of LED arrays and small modules. This sample table can be upgraded with an XY translation stage (LEDGON-131) so that e.g. an LED module located off-center can be positioned in the center of rotation. Optical probe LEDGON-120 LEDGON 100 is compatible with all spectrometers suppliedby Instrument Systems. The CAS 140CT is ideal because it has a very large dynamic measuring range. This permits fully automated measurement of the radiation pattern, even for test specimens where the intensity varies significantly over the angle. Optional sample table LEDGON-130 Optical probes with diffusers (LEDGON-120 and LEDGON- 121), and an optical probe optimized for modules (LEDGON-125) can be supplied for measuring light radiation. The latter is based on a small integrating sphere that allows accurate measurements to be obtained also for test specimens radiating light from an extended surface. Control and Evaluation Functionalities with SpecWin Pro Software The LEDGON 100 is operated using SpecWin Pro Software from Instrument Systems. Two control modes are available: The sequence mode that allows the radiation pattern of the test specimen to be recorded for the two spatial axes (theta and phi) at equidistant angular increments. Parameters can be saved for subsequent evaluations. The test series mode, which permits free definition of test sequences, i.e. measurements at any definable sequences of angular positions. Other add-ons of SpecWin Pro software and appropriate instrumentation also permit current, voltage and temperature to be included in the goniometric analysis, as well as control and measured variables. For example, Keithley 2400 and Keithley 2600 sourcemeters can be easily installed as an add-on.

5 Accurate Measurements of Luminous Flux and Radiant Power The LEDGON 100 Goniophotometer is also ideal for precise measurement of radiant power and luminous flux. Potential measuring errors that can be caused by the geometry of integrating spheres are not encountered with goniometric measurement of luminous flux. Instrument Systems has developed an appropriate function for SpecWin Pro software that allows fully automated measurement. However, it should be noted that the angular range for the theta axis is ± 100 and hence a measurement is not possible in 4π. Display Options and Output Formats The graphics window used to visualize the measurements is the central element of the user interface in the goniometer mode of SpecWin Pro. Five different displays are available for the radiation pattern: a radial, a semiradial and a cartesian view, a two-dimensional spherical display, and a 3-D view. Display of the luminous intensity distribution curve is also important for general lighting. The measured data can be exported in the IES and EULUMDAT format for use in simulation programs.
