We offer a standard measurement menu for measuring the spectral transmittance and reflectance of materials, the scattering characteristics of transmittance and reflectance, and the luminous intensity distribution characteristics of light-emitting bodies.
"Scattering Measurement Using a Goniophotometer" The optical properties of materials such as films (transmission scattering measurement, reflection scattering measurement) are measured by automatically rotating the detector while illuminating with various types of light according to the purpose. ● Measurement Application Examples - Measurement of angular variation in transmission and reflection characteristics of films, glass substrates, etc. - Measurement of BRDF and BTDF "Spectral Transmission and Reflection Measurement Using a UV-Visible-Near Infrared Photometer" Covers the measurement range from ultraviolet-visible to near-infrared, analyzing the spectral characteristics of physical properties. ● Measurement Application Examples Measurement of transmission, reflection, and optical characteristics of products using optical components made of glass and plastic materials.

Company information
Since the early 2000s, our company has a history of developing various evaluation software for imaging optical systems such as eyeglass real image simulators and digital cameras, as well as image processing software for interferometers, on a contract basis for various equipment manufacturers. The "Lighting Simulator" series is a purely domestic original package software that simulates lighting optical systems, based on the accumulation of software technology in the optical field, under the technical guidance of Dr. Genta Ushiyama (Engineering), author of books such as "Simulation Optics: For Diverse Optical Design" (Tokai University Press) and "Learn Solidly! Basic Knowledge of Optical Design" (Nikkan Kogyo Shimbun). Leveraging the strengths of our in-house development, we have a development system that quickly translates user requests into version upgrades and flexibly responds to the development of auxiliary tools and customization.
