Colorimetry involves physical optics, visual physiology, and visual psychology. Colorimetric analysis is a topic that can be found in many areas and it is a necessary subject that should be covered at universities and colleges. LEOI-70 is designed for colorimetric education at college and university level and it is an experimental system with a high performance-to-cost ratio. LEOI-70 is the basic model and LEOI-70A is the enhancement model. LEOI-70A includes a four-color area light source so that the colorimetric analysis of an illuminant can be performed.

LEOI-63 is specifically designed to measure blackbody radiation energy or the radiation energy of an emission light source. This system can automatically record the radiation spectrum of an emission light source. By varying the color temperature of the light source, the phenomenon as described by Wien`s displacement law can be observed through the recorded radiation spectrum of the light source. This system can be used to precisely verify the Planck`s law and Stefan-Boltzmann`s law. Based on the Planck`s formula, system software can calculate the theoretical radiation spectrum of an absolute blackbody at any given temperature.
