RT-300, a state of the art BSDF measurement system by J & C Technology

Nov. 2, 2011
Date Announced: 02 Nov 2011 BSDF (Bidirectional Scattering Distribution Function) data becomes a must to achieve better efficiency in optical design, especially for LED light sources and solar cell. The reflectance of the reflector cup within the LED, the reflectance and the transmittance of the diffuser are necessary data for optical simulation. With the accurate and fine data, the result generated by the simulation software is more trust-able, and the cost for poor design is reduced.RT-300, by J & C technology, is a computer based fully automatic BSDF measurement system. As indicated by the name, BSDF which is the general term of BRDF (Bidirectional Reflectance Distribution Function) and BTDF (Bidirectional Transmittance Distribution Function), RT-300 is capable of measuring the BRDF data and BTDF data. It is equipped with 3 motorized axis which can cover the semi-sphere area. This system also provides an easy way to maintain the azimuth angle and the polar angle of the incident light, while most of the scattering systems have a capability to maintain the polar angle only.There are two light source modules (halogen light source and LASER light source with a variety of wavelengths from 405 to 980 nm) that are exchangeable. With these exchangeable light sources, the BSDF of a material under test can be fully realized.RT-300 has two detector modules, spectrometer and photo detector. Colorimetric measurement can be realized with the spectrometer and halogen light source. The 107 dynamic range is fulfilled with the photo detector module.With RT-300, user can visualize the BSDF at different wavelength if spectrometer is used as the detector module. The data can be presented as 2D iso-plot and 3D iso-plot, also be imported by will known optical simulation software, such as ASAP, Light Tools.In addition to the example materials mentioned in the first paragraph, RT-300 can also measure the BSDF of any kind of materials such as plastic, paper, metallic, paints and glass with ITO coating. Also, RT-300 is compact and very easy to use.None motorized version is also available for the general reflectance and transmittance measurement at fixed angles.
