Slow Axis Collimators
Beam Shaping: SAC-Lenses reshape the elliptical beam emitted by diode lasers into a more circular or symmetric profile, making it easier to focus or collimate further downstream in optical instruments.
Improved Beam Quality: By reducing the divergence angle along the slow axis, SAC-Lenses enhance the overall quality of the laser output, resulting in a high-quality, symmetric beam profile.
Beam Collimation: In addition to shaping the beam profile, SAC-Lenses collimate the beam along the slow axis, ensuring that the beams remain parallel and maintaining beam integrity over long distances.
Divergence Control: SAC-Lenses effectively control the overall divergence of the laser beam by reducing divergence along the slow axis, leading to better focusing and increased range for applications such as laser cutting or engraving.
Applications: Laser Materials Processing, Medical Applications, Optical Instrumentation, Laser Engraving and Marking, etc.
Slow Axis Collimators (SAC-Lenses) are specialized optical components designed for use in lasers, particularly diode lasers. Their primary function is to shape and control the output beam, transforming it from an asymmetric profile to a more symmetrical one.
