Lenses for use with electronic imaging systems, e.g., systems employing CCDs, are provided. The lenses employ at least two lens elements, at least one of which is a dyed plastic lens element whose average percentage transmission for wavelengths between 400 nm and 550 nm is greater than its average percentage transmission for wavelengths between 550 nm and 700 nm. Through the use of such a dyed plastic lens element, the need for a separate spectral response flattening filter is eliminated thus reducing the cost, complexity, size, and weight of the electronic imaging system.
