Universal sensor system for auto dimming control for different spectral outputs

A rearview system comprising:

• a light sensor assembly having:
• a photosensor operable to detect light and generate a signal based, at least in part, on the detected light;
• a dichroic filter in optical communication with the photosensor and operable to filter light, the dichroic filter configured to substantially inhibit light having a wavelength of greater than a predetermined wavelength from transmitting therethrough, wherein the dichroic filter comprises a plurality of filter layers, the dichroic filter being configured to generate sensor responses in the photosensor similar to the response of a human eye;
• and
• a rearview assembly having an electro-optic element comprising an electro-optic medium and operable to variably change the amount of light passing through the electro-optic medium based, at least in part, on the signal,
• wherein the dichroic filter comprises a first portion comprising a plurality of filter layers and capable of substantially inhibiting the passage of light having a wavelength of greater than 650 nm through the dichroic filter and a second portion comprising a plurality of filter layers and capable of substantially inhibiting the passage of light having a wavelength of less than 400 nm through the dichroic filter.
