The Condenser Lens LF-N is an optional lens for the LF800-N to condense light beam for narrower beam and closer working range to expand possibility for totally new underwater imaging with pinpoint lighting etc. Usable for macro imaging with constant light source as the lens increases center brightness. The lens has screw mount on its front end to stack another Condenser Lens LF-N to have even closer working range and narrower beam. Rear end of the lens barrel can hold packaged "Red Filter LF-N" or "Blue Filter LF-N".
The Condenser Lens LF-N is designed for underwater use only and not usable on land.

(*1) Theoretical working distance to illuminate a subject without significant center spot and not same as the maximum distance this product can deliver light.
(*2) When illuminating a subject at approx.55cm/21.6in away or greater, using Condenser Lens LF-N will have bigger lit area.
