Aspheric Lens Ultrasonic Cleaning MachineVGT-1509FH

In the field of precision optical manufacturing, a speck of dust at the micron level is enough to ruin an expensive coating process.

In modern optical manufacturing, aspheric lenses, as core components of high-end imaging systems, have cleanliness that directly determines the final product's imaging quality and performance. A seemingly insignificant speck of dust or a barely noticeable fingerprint can cause fatal defects during the coating process, leading to the entire lens being scrapped. To address this industry pain point, the Weigute VGT-1509FH Coated Mirror Ultrasonic Cleaning Machine was developed, becoming a key equipment to ensure coating yield.

Applications and Cleaning Challenges of Aspheric Lenses:

As a precision optical component, aspheric lenses, with their unique curved design, can effectively reduce aberrations such as spherical aberration and astigmatism in optical systems, playing a pivotal role in modern optics. From 3D structured light facial recognition systems in smartphones to sensor lenses in autonomous vehicles, and high-definition imaging lenses in security applications, the use of aspheric lenses is continuously expanding.

These high-end applications impose extremely stringent requirements on lens imaging quality, where even the slightest contamination can affect the entire system's performance.

In optical manufacturing processes, coating is a critical step, and pre-coating cleaning is particularly vital. According to search results, the typical process flow for optical components (mirrors) includes steps such as "lens raw material—cleaning—vacuum coating—cleaning—film application."

Any dirt spots or water residues on the workpiece surface will lead to coating failure. For this reason, ultrasonic cleaning machines specifically designed for optical components have become indispensable equipment for ensuring coating yield.

Technical Features of Weigute VGT-1509FH:

The Weigute VGT-1509FH Coated Mirror Ultrasonic Cleaning Machine is a professional device designed for high-precision optical component cleaning. This equipment integrates 15 functional tanks and is equipped with multiple high-end configurations, including an agitation system, circulation filtration system, automatic constant temperature system, ultrasonic cleaning system, and timing system.

Its cleaning principle is based on the impact of "cavitation" generated by high-frequency ultrasound and the system's continuous up-and-down motion, which increases liquid friction, enabling contaminants on the workpiece surface to be quickly removed, achieving high cleanliness.

The cleaning cycle of this device ranges from 3 to 11 minutes and can be flexibly adjusted according to actual production progress.

This efficient cleaning capability is attributed to its carefully designed agitation mechanism—the agitation motor drives a linear slider up and down via an eccentric wheel, ensuring continuous agitation, reducing friction resistance, and thereby enabling the agitation frame to move the cleaning basket up and down within the cleaning tank.

Compared to conventional cleaning equipment, the Weigute VGT-1509FH also pays special attention to noise control, keeping ultrasonic noise within a certain range without compromising ultrasonic effectiveness, effectively improving labor efficiency.

Importance in Optical Manufacturing:

In the optical manufacturing process, the cleaning step, though inconspicuous, is crucial. Without thorough pre-cleaning, subsequent coating processes cannot achieve the desired results. The Weigute VGT-1509FH is specifically designed for pre-coating treatment, addressing multiple pain points in optical component cleaning: on one hand, the device can remove various contaminants such as particulate matter, grease, and fingerprints from the lens surface; on the other hand, through slow pull dehydration technology and steam bath drying technology, it ensures no water stains or residues remain on the workpiece surface.

For high-precision aspheric lenses, maintaining surface integrity is another challenge during cleaning. Overly aggressive cleaning methods may damage the fine structures on the lens surface, but the Weigute VGT-1509FH, through precise ultrasonic frequency control and an agitation system, achieves efficient cleaning without damaging the workpiece. This balance is crucial for ensuring the surface quality and optical performance of optical components.
