"Spectrophotometric measurement of spectral transmittance and reflectance using a UV-visible near-infrared analyzer" - Measurement of transmittance for lenses and glass - Measurement of reflectance for other materials "Goniophotometer" - Measurement of angular variation in transmittance and reflectance characteristics of films, glass substrates, etc. - Measurement of the degree of diffusion of diffusing substrates - Measurement of BRDF and BTDF - Others
Detailed information
-
It covers the range from ultraviolet-visible to near-infrared and mainly measures the spectra of solid materials such as glass and plastic.
-
A goniophotometer is a device that measures the light scattering characteristics of transmission and reflection of 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.

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 marketed "Lighting Simulator CAD" and have 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.
