The AGLS is a sensor accessory to the Accu-Gold family of products that include the Accu-Gold digitizer and Accu-Gold Touch systems. The AGLS is an excellent Quality Control/Quality Assurance solution for measuring luminance and illuminance.
The base unit of the light sensor contains a silicon photo diode that is exposed to ambient light through an optical filter which very accurately simulates the spectral response of the human eye (the photopic response). In this way, the light sensor measures illuminance of the ambient in units of lux.
A luminance adapter can be attached to the base unit in front of the photo‐diode for the measurement of luminance of a monitor in cd/m2 units. The aperture of the Luminance Adaptor is 10‐mm in diameter.
The Accu‐Gold digitizer and Touch systems automatically detect the presence or absence of the luminance adapter and automatically select the appropriate measurement and units.
