Laser Cutting Protective Lens Focus Lens Collimating Lens

Fiber laser cutting is generally used for medium- to high- power metal material cutting. The typical optical path transmission sequence is as follows: the laser beam is collimated and expanded into a parallel beam through a collimating lens, then focused onto the working position using a focusing lens. A protective lens is placed after the focusing lens to prevent splatter from damaging the focusing lens during the cutting process. Additionally, in an L-shaped cutting head, the collimated beam is deflected 90 degrees by a 45-degree reflective mirror before entering the focusing lens for precision cutting.

Product Description

>> Product Advantage

1. Outstanding Performance

The Comprehensive Advantages of Laser Optical Components

Laser optical components set industry benchmarks with their high damage threshold, remaining intact under high-power laser exposure.

High smoothness and ultra-smooth surfaces achieve low scattering and high transmittance, ensuring maximum laser energy performance.

2. ISO-standardized Clean Production Process

This process reduces potential contamination introduced during production at the source and significantly lowers the probability of recontamination of optical components after activation. As a result, it demonstrates a slower damage growth rate during use.

3. Innovative Coating Design

Utilizes multilayer coating technology to evenly distribute the electric field, effectively avoiding high concentrations of electric field intensity. This significantly enhances the laser-induced damage threshold.

Using hafnium oxide as the coating material, known for its low absorption rate, not only improves coating performance but also ensures the stability and durability of components in high-power applications.
