Reflectance / Transmittance Meters and Others
A diverse product line of instruments to assess many different optical properties of specimens. These products include assessing color appearance analysis of surface reflection and transmission modalities. They are applicable throughout the color supply chain.
D65AC / D65ACIE D65 Standard Light Source
Determining an accurate visual evaluation. This is a standard light source used to visually evaluate the color of an object, as specified in JIS Z 8720 "Standard illuminants and sources for colorimetry." It can perform metamerism tests, with the equipped D65 and A light sources. D65AC allows the user to adjust the brightness.

NS-1Retroreflection Meter
Determines the performance of reflective boards and evaluate their quality. This instrument evaluates the retroreflectivity of reflectors for cars, reflective safety signs, reflective traffic warning signs etc. by shining them with light and measuring the light reflected back. It does not require a dark room, and comes with a calibration standard plate for comparison with the test results (value set by the Japan Vehicle Inspection Association comes separately).
