CO2 laser lenses play a critical role in shaping, focusing, and directing the laser beam for various applications. In this comparison, we'll evaluate three different lenses: Lens A, Lens B, and Lens C. Each lens is designed to excel in specific scenarios, making them suitable for a range of applications.
1. Lens A: Precision Focusing Lens
Focal Length: Shorter focal length for high precision and fine-detail work.
Coating: Multi-layer anti-reflective coating for improved energy transmission.
Material: High-quality ZnSe (Zinc Selenide) lens material.
Aperture Size: Small aperture suitable for intricate engraving and cutting.
Performance: Excellent beam quality preservation.
Lens A excels in applications requiring fine details and high precision. Its short focal length and anti-reflective coating make it ideal for intricate engraving, marking, and micro-cutting. The small aperture size ensures optimal energy concentration, resulting in precise material removal without excessive heat buildup.

2. Lens B: High-Power Cutting Lens
Focal Length: Medium focal length for a balance of precision and cutting efficiency.
Coating: High-damage threshold coating for handling high-power laser beams.
Material: ZnSe or GaAs (Gallium Arsenide) lens material for increased durability.
Aperture Size: Moderate aperture suitable for general cutting and engraving.
Performance: Designed to handle higher laser power levels.
Lens B is optimized for high-power cutting applications. Its medium focal length strikes a balance between precision and cutting efficiency, making it suitable for various materials and thicknesses. The high-damage threshold coating ensures the lens can withstand intense laser beams without degradation.
