The plateau filters are designed to transmit a constant % transmission over a specific wavelength region. These plateau filters will transmit an average transmission of 20% from 400nm to 500nm. At 500nm the transmission steps up to 50% from 500nm to 600nm. At 600nm the transmission steps up to 80% from 600nm to 700nm.
