Featured Video: CA-2500 2D Color Analyzer   Blog: Why Color Measurement Can Inspire the Lighting Industry
Konica Minolta has been a leading manufacturer of display and light-source measurement instruments for over 20 years. Konica Minolta instruments are hand crafted and tested to ensure the highest level of quality and endurance. Watch the newest video featuring the CA-2500 2D Color Analyzer. You will see first-hand how this high-end imaging photometer is used to measure luminance and chromaticity of simple displays.

  Photometers are devices that allow the user to analyze quantitative measurements of direct, ambient, and reflected light. These devices provide quantitative measurements that in turn, are used by engineers to develop custom lighting systems. This also allows engineers to choose materials that use ambient and reflected light to maximize the utility of indoor and outdoor lighting. Lighting is a very important aspect of design.

Photometry and the Human Eye   Understanding LED Illumination
Photometry involves measurements of the psychophysical attributes of electromagnetic energy that is visible to the human eye. The use of the term 'luminous', which refers to visible light, defines photometry in terms of human perception. Photometry became a modern science in 1942, when Commission Internationale de l'Eclairage (CIE) met to define the response of the average human eye. CIE measured the light-adapted eyes of a sizeable sample group, and compiled the data into the CIE Standard Luminosity Function (widely known as photopic curve - chromatic perception at normal state, and scotopic curve - achromatic perception at low level of illuminance.)
                               
 
Dr. Nisa Khan has been performing pioneering optical research for over 25 years. In 2006, Dr. Khan founded IEM LED Lighting Technologies, an independent research and engineering company that provides LED feasibility studies for the entertainment and signage industries, & provides design and development solutions for general lighting applications. She wrote a book entitled, Understanding LED Illumination, in which she used Konica Minolta instruments to perform her measurements.
