In the field of precision optical manufacturing, the cleanliness of filters directly affects the performance of laser instruments. Laser spectral line filters, as the core optical component that filters out specific wavelengths and transmits target spectral lines, even if there are micrometer-level contaminants remaining on their surfaces, can lead to a decrease in transmission rate or a reduction in the laser damage threshold. Vigot, targeting this specific niche, has launched the laser spectral line filter ultrasonic cleaning machine, represented by models such as VGT-1309FH, providing cleaning solutions for optical manufacturing enterprises that balance cleanliness and safety.

The core of ultrasonic cleaning lies in the "cavitation effect". The high-frequency oscillation signal emitted by the cleaning machine is converted by the transducer into high-frequency mechanical oscillations, generating tens of thousands of tiny bubbles in the cleaning solution. These bubbles form and grow in the negative pressure zone, and then instantly close, generating local shock waves that can exceed 1000 atmospheres. For laser spectral line filters, this impact force can penetrate the microscopic crevices on the surface of the lenses and remove the particles attached to the surface of the film layer without introducing scratches or fiber residues like mechanical wiping. Of course, the selection of frequency and power is crucial - too high may damage the sensitive optical film layer, while too low may not completely remove sub-micron particles.

Equipment Structure and Process Configuration:

The VGT-1309FH ultrasonic cleaning machine for laser spectral line filters takes into account the special nature of optical components in its structural design. Taking this machine as an example, it is made of 304/316 stainless steel and features an integrated multi-stage process design that can meet the requirements of batch cleaning. The entire machine consists of an ultrasonic generator, transducer, cleaning tank, liquid storage tank, circulation filtration system, automatic constant temperature heating system, agitation system, exhaust hood, and electrical control cabinet. In the cleaning process, the equipment supports the combination selection of multiple processes, including ultrasonic rough cleaning, fine cleaning, rinsing, circulation filtration, high-pressure spraying, and hot air drying. This modular design enables users to flexibly configure the process flow according to the specific contamination type and cleanliness requirements of the filter glass.

Core Features: Balance of Cleanliness and Safety

Laser spectral line filters are high-value optical components, and any damage during the cleaning process may result in irreversible losses. VGT cleaning machines have made targeted designs in this regard: The circulation filtration system continuously removes particulate matter in the cleaning solution to prevent the re-adsorption of stripped contaminants; the IPA steam bath washing and drying system is suitable for dehydration and drying of glass and lens-type workpieces, avoiding water stains; the ultrasonic power is continuously adjustable to facilitate matching of appropriate ultrasonic intensity for different film layer types of filter glass. In addition, the equipment adopts an imported high-sensitivity fireproof and explosion-proof system, providing additional safety guarantees when using organic solvent cleaning.

Application Value: From Process Compatibility to Yield Improvement

Laser spectral line filters are widely used in laser analysis instruments, medical laser equipment, and biochemical testing instruments. In these application scenarios, the pre-cleaning of the coating and the cleaning of the finished products are both critical processes. If the pre-coating cleaning is not thorough, the remaining polishing powder or organic substances will cause a decrease in the adhesion of the film layer; improper cleaning of the finished products may damage the already coated precision film system. The multi-chamber process and programmable control capabilities of the VIGOTT cleaning machine enable it to adapt to different production rhythms ranging from laboratory small-scale to production line large-scale, helping optical manufacturing enterprises stabilize cleaning quality and reduce defects in coating and product scrapping caused by cleanliness issues.

The VIGOTT laser spectral line filter ultrasonic cleaning machine is based on the cavitation effect and through the combination of multi-chamber processes, cyclic filtration, and adjustable power design, it seeks a balance point between cleanliness and component safety. For manufacturing enterprises in the laser optics field, the value of such specialized cleaning equipment lies not only in replacing manual wiping, but also in transforming the cleaning process from "based on experience" to a controllable and repeatable standardized process.
