In the application of lasers, two unavoidable concepts are frequently encountered: collimation and focusing. Beginners often find it difficult to distinguish between the two. For instance, in laser marking, cutting, welding, cleaning, and other processing procedures, the object to be processed must be placed at the focal point to achieve the most concentrated energy. In this case, focusing is required, and the focusing lens used here is generally referred to as a field lens.
Application Type | Definition | Key Applications | Lens Used | Key Effect |
Focusing | Concentrates laser energy at focal point | Marking, Cutting, Welding, Cleaning | Focusing Lens (Field Lens) | Maximizes energy density for material processing |
Collimation | Transforms divergent beam into parallel beam | Long-distance transmission | Collimation Lens | Maintains beam profile consistency |
Bena Optics offers a range of optical lenses specifically designed for both collimation and focusing applications. These lenses are crafted to provide the precision and reliability required in laser-based processes.
Focusing with Plano-Convex Lenses
When using a plano-convex lens for focusing, the convex surface is oriented towards the incoming light. This configuration helps to converge the beam to a focal point, ensuring that the laser energy is concentrated where it is needed most. Bena Optics' focusing lenses are engineered to deliver superior optical performance, minimizing aberrations and maximizing energy efficiency.
Collimation with Plano-Convex Lenses
For collimation purposes, the plano-convex lens is oriented with its flat surface towards the incoming light. This setup ensures that the divergent beam from the optical fiber is converted into a parallel beam with minimal divergence, maintaining a steady beam profile over distance. Bena Optics' collimation lenses are designed to provide exceptional beam quality, making them ideal for applications that require long-distance beam propagation.
Understanding the distinct roles of collimation and focusing is essential for maximizing the performance of laser systems. Bena Optics' advanced optical lenses are tailored to excel in both these critical areas, providing the precision and reliability needed for successful laser applications.
