Lightweight, Non-Contact and Flexible Laser Cleaning Solution for Rust, Paint, Oxide and Surface Contaminant Removal

The JGZOE Pulse Laser Cleaning Head is designed for precise, efficient and flexible industrial surface cleaning. Using high-energy pulsed laser beams, it can remove or ablate unwanted surface layers such as rust, oxide, paint, coatings, oil and other contaminants.

Compared with conventional grinding, sandblasting or chemical cleaning methods, pulsed laser cleaning provides a non-contact and highly controllable cleaning process. With appropriate laser parameters, contaminants can be removed while minimizing unnecessary thermal and mechanical impact on the underlying material.

Its lightweight handheld design also makes it suitable for complex components, curved surfaces, weld seams and areas that are difficult to access with conventional cleaning equipment.

When selecting an F-Theta scan lens, one of the first parameters you need to confirm is the laser wavelength.​
1064nm, 532nm, 355nm, and 10.6μm lasers are widely used in laser marking, cutting, engraving, welding, and precision micromachining. Although they may use similar scanning systems, this does not mean they can simply share the same F-Theta lens.​
Why?​
The answer mainly comes down to optical material, coating design, transmission, focusing performance, and laser damage threshold.

Custom F-Theta Scan Lens Solutions for Laser Marking, Cutting and Micro Machining

In modern laser manufacturing, achieving high precision, stable processing quality, and high production efficiency has become increasingly important. The F-Theta lens, also known as a laser scan lens, plays a critical role in laser scanning systems by providing a flat focal plane and maintaining consistent spot quality across the entire scanning field.

As a professional optical manufacturer, JG Optics provides custom-designed F-Theta lenses for a wide range of laser applications, including fiber laser marking, laser cutting, semiconductor processing, PCB drilling, micro machining, and precision manufacturing.

Introduction

In laser processing systems, the choice of optical components directly affects accuracy, efficiency, and overall performance. Two commonly used optics are the F-theta lens and the standard focusing lens. Although both are designed to focus laser beams, they serve different purposes and are optimized for different applications.

Understanding the differences between these lenses can help manufacturers, integrators, and engineers select the right solution for their laser systems.

In modern laser processing systems, F-theta lenses play a critical role in determining marking accuracy, processing uniformity, and overall system performance. However, as the demand for larger working fields continues to grow, a common optical challenge becomes more significant—edge distortion.

So why does edge distortion happen in large field F-theta lenses, and how can it be controlled?

In modern laser processing systems, maintaining stable laser spot quality across a large scanning field is one of the most critical factors affecting processing accuracy, consistency, and yield. As applications such as laser marking, engraving, cutting, and micro-machining continue to expand, especially in large-format processing, laser spot instability becomes a key limitation that engineers must solve.

This article explains the main causes of laser spot instability in large field scanning and provides practical methods to improve performance in real industrial systems.

Turning Market Expansion into Real Production Advantages

The global laser processing industry is entering a new phase in 2026, where precision, stability, and scalability are becoming the core decision factors for optical component selection.

Among all key optical elements, high-precision F-theta lenses are playing an increasingly critical role in enabling next-generation laser manufacturing systems.

For OEMs, integrators, and industrial laser users, this is not just a market trend—it is a clear signal to upgrade optical systems to stay competitive.

In modern laser processing systems, F-theta lenses are designed to provide a flat-field scanning response, where the output position on the work surface is proportional to the input scanning angle.

However, as laser systems move toward larger working fields and higher processing efficiency, edge distortion becomes increasingly noticeable. This is a common challenge in high-power and high-precision laser applications.

So why does this happen—and what causes it?

When choosing an F-theta lens for a laser system, one of the most important decisions is the lens material.
The two most common materials used in laser scan lenses are Fused Silica and ZnSe (Zinc Selenide).

Different laser wavelengths require different optical materials, and selecting the wrong lens can seriously affect marking quality, transmission efficiency, and lens lifetime.

In this article, we compare Fused Silica vs ZnSe F-theta lenses in terms of wavelength compatibility, performance, durability, and industrial applications.

We are pleased to announce that JGZOE Sub-Lattice Optical will participate in TCT Asia 2026, one of the most influential additive manufacturing exhibitions in Asia.

The exhibition will be held at National Exhibition and Convention Center (Shanghai), bringing together global manufacturers, engineers, and technology innovators in the 3D printing and additive manufacturing industry.
