▣ BSDF(Goniometry Type) System


■ Evaluation of scattering characteristics by wavelength 

■ 2D, 3D, BSDF (BRDF, BTDF) evaluation 

■ Transmission and reflection characteristics for surface analysis

■ Data compatibility with optical design programs

    (ASAP, Speos, TracePro, Light Tools)


The RT system adopts the goniometer method, which is traditionally used for scattering characteristics (Bi-Directional Scattering (Reflectance / Transmittance) Distribution), and is designed to measure reflectance and transmittance at various angles by randomly changing the angle of the incident light and the measurement part. Spectroscopic measurements at arbitrarily set angles are also possible. In addition, the optical system is controlled by dedicated software, and various colorimetric systems are calculated using the measured spectral values ​​and displayed on various analysis graphs. For precise measurement, it can be equipped with two light sources: halogen (360nm ~ 1,500nm) and laser (405nm, 532nm, 630nm, 780nm, 850nm, 980nm), and has the advantage of being able to evaluate the scattering characteristics of visible light and infrared light. In addition, it has the best dynamic range and is equipped with optimal conditions to simultaneously analyze specular components such as mirrors and haze in a low-diffusion area.
