Product Description
A collimating lens is a key optical component that adjusts the direction of light propagation through refraction or reflection, converting divergent or convergent light into a parallel beam (collimated beam). In laser processing and communication applications, it is used for industrial applications such as laser cutting and welding, as well as beam coupling in fiber-optic communications.
