Detailed information
-
A goniophotometer is a device that measures the light scattering characteristics of transmission and reflection for materials such as glass substrates, metals, and films. By using a standard white board and performing value calibration, the BRDF of the sample can be determined.
-
It covers the range from ultraviolet-visible to near-infrared and mainly measures the spectra of solid materials such as glass and plastic.

Company information
"Contributing to Society through Light Simulation" Our representative director, Ritsuo Suzuki, has been developing evaluation software for imaging optical systems such as eyeglass real image simulators and digital cameras, as well as image processing software for interferometers, based on ray tracing technology since the early 2000s when he joined our parent company, Best Media Inc. He has supported various companies through these developments. Building on the technology cultivated there, we developed and sold "Lighting Simulator CAD" and provided various optical services. In October 2021, to enhance branding in the optical industry and attract specialized talent, we split from Best Media Inc. and established Camerium Inc. "Camerium" is a coined term derived from "Microscopium" and "Telescopium," symbolizing our aspiration to shine in the optical industry, akin to the "Camera" constellation.
