What is a Laser Lens?

A laser lens is an optical component designed to focus, collimate, or direct laser beams with high precision. Whether used in cutting, marking, engraving, or welding, the quality of the laser lens significantly influences the overall performance of any laser system.

Laser lenses must be carefully engineered to handle:

• High-power densities

• Wavelength-specific transmission

• Thermal resistance

• Precise focal distances

LaserChina, a globally recognized name in the laser optics industry, is leading this transformation by offering a vast selection of laser lenses crafted for professional and industrial-grade applications.

Why LaserChina Laser Lenses Stand Out

LaserChina's reputation is built on technical precision, material quality, and optical innovation. Here’s what separates their lenses from conventional options:

1. Material Excellence

• Manufactured from top-tier fused silica and ZnSe (Zinc Selenide), ideal for CO2 and fiber laser systems.

• Scratch-resistant coatings extend lens life under high thermal loads.

2. High Transmission Rates

• Anti-reflective coatings for maximum light throughput.

• Optimized for wavelengths like 10.6 µm (CO2) or 1064 nm (fiber lasers).

3. Precision Polishing

• Surface irregularity within λ/10 (at 633 nm), ensuring optimal focus and beam shape.

• Tight focal tolerance reduces beam scatter and maintains intensity.

Applications Across Industries

LaserChina’s laser lenses are tailored for diverse industrial applications. Below is a breakdown of use cases:

How to Choose the Right Laser Lens from LaserChina

Choosing the correct lens can make or break the efficiency of a laser system. Consider these critical parameters when selecting a lens:

Focal Length

• Determines the spot size and depth of field

• Shorter focal lengths for fine detail; longer for deep cuts

 Lens Diameter

• Must match the housing and beam diameter

• Typical sizes: 18mm, 20mm, 25mm, 50.8mm

 Coating Type

• AR-Coated lenses for reduced reflections

• Wavelength-specific coatings for improved clarity

 Working Distance

• Critical in applications with moving components or uneven surfaces
