Eye Response Detectors (series -E)

Eye Response Detectors (series -E) Centronic Series E photodetectors use the successful Series 5T chip together with high quality glass colour correcting filters. The resulting spectral response approximates to that of the human eye making this device ideal for use in general photometric applications.

Electrical / Optical Specifications

Unit Conversion Table for Illuminance

The Series E photodiodes have been colour corrected to provide a photopic response. They can be used as low cost illuminance monitors for many instrument and industrial applications. The following table provides useful conversion factors for various illuminance units.
