Collimating Lens
Collimating Lenses are precision optical components designed to convert divergent light from a point source into a parallel or nearly parallel beam. By providing accurate beam collimation and focusing performance, these lenses improve optical efficiency and system stability. Chenyu Optics manufactures collimating lenses in BK7, fused silica and sapphire, uncoated or with UV AR, VIS AR and NIR AR coatings for laser, fiber coupling and imaging systems.
Collimating Lens Overview
Collimating Lenses are precision optical components designed to convert divergent light from a point source into a parallel or nearly parallel beam.
By providing accurate beam collimation and focusing performance, these lenses improve optical efficiency and system stability. Manufactured from high-quality optical materials including BK7, fused silica and sapphire, collimating lenses offer high transmission, low optical distortion and reliable performance. They are widely used in laser systems, fiber coupling, optical sensors, imaging systems and laser measurement equipment.
Chenyu Optics supports custom collimating lens manufacturing according to customer drawings, including custom diameter, focal length, material and coating design for prototype and repeat production.
