The KES410ACA is quite a different looking laser lens for the Playstation 3 40GB console. It features two lenses on it's optical block. One of the KES410 lenses is used for blu-ray and the other is used for DVD/CD. The 410's lens setup really does add life to the Playstation 3 laser as it runs off two seperate coils - therefore reducing wear and tear between each laser wavelength.
