This is a tool designed for adjusting the focus of the laser beam on our PLH3D-Series with the High-Resolution Lens. It is valuable to quickly change the focus of the beam when a different working distance or focus spot size is desired, often depending on the material properties or other constraints of the application.
This Mounted Aspheric lens is useful to collimate or focus laser light in the visible wavelength regime. The aspheric design nearly eliminates spherical aberration without needing multiple optical elements. It has a broadband AR coating of 400-700 nm, allowing it to be used for various applications.
This Mounted Triplet 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 mm allows it to focus laser light to a small spot.
