This High-Resolution Lens can be used to variably focus or collimate the laser light with reduced aberration due to its triplet (three-element) design. Its relatively long effective focal length (EFL) of 8.0 mm allows it to focus laser light to a small spot.
This lens is included with our PLH3D-Series laser engravers and is compatible with our PLH3D-Series Focus Adjuster accessory. It is easy to clean the front surface of the lens if it becomes dirty when engraving, which may be done with Isopropyl Alcohol (IPA) and an optical wipe. However, in some cases, it can be necessary to replace the lens. It is recommended to purchase additional lenses with PLH3D-Series laser heads if they will be used in an environment where dust, smoke or oil may contaminate the lens surface.
