Insuring that self-emissive technologies, such as information display monitors, LED lighting, or digital projectors, meet or exceed performance specifications requires precise characterization through accurate measurements. While there are several measurement technologies available for device characterization, two of the most commonly-used instrument types are filter colorimeters and spectroradiometers.

Filter Colorimeters

A basic filter colorimeter consists of:

• Collection Optics: This could be a... More
