Lambda - Model LEOI-70 -Experimental System for Colorimetry

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.
