Ultrasonic cleaning machines for lenses and glasses

Ultrasonic lens cleaning has become a key solution for maintaining the clarity, integrity, and performance of all types of optical lenses. This technology not only enables deep, contactless cleaning but also guarantees superior results to manual methods, especially on items as delicate as eyeglasses, optical crystals, microscope lenses, magnifying glasses, and other technical glass elements.

Ultrasonic lens cleaning involves immersing lenses in a cleaning bath where high-frequency ultrasonic waves are generated. These waves produce thousands of microbubbles that collapse in a controlled manner (cavitation), dislodging adhering dirt particles without damaging the lens surface. The result is a thorough and uniform cleaning even in hard-to-reach areas such as bevels, threads, curvatures, or microcracks.

This process is widely used in opticians, ophthalmic clinics, research laboratories, optical instrument repair shops, and the lens manufacturing industry.

What types of lenses can be cleaned with ultrasound?

Ultrasonic cleaning is suitable for a wide variety of lenses and optical components, including:

• Ophthalmic lenses (prescription glasses, sunglasses, etc.)
• Precision optical glass (for microscopes, cameras, projectors, etc.)
• Rigid or semi-rigid contact lenses
• Lenses for scientific and medical instruments
• Technical glass and industrial optical parts
• Light filters, viewfinders, and prisms for optical devices

Ultrasonic cleaning effectively removes dust, fingerprints, oils, grease, chemical residues, microorganisms, and microscopic particles, leaving the surface completely free of contaminants.

Advantages of the Ultrasonic Lens Cleaning System

Using ultrasonic lens cleaning machines offers multiple benefits compared to conventional manual or chemical methods:

1. Deep cleaning without damaging the surface
Thanks to cavitation, there is no friction or direct contact with the lenses, preventing scratches or alterations to the material.

2. Elimination of microscopic contaminants
The ultrasonic system acts at the microscopic level, ensuring complete cleaning, even in areas where physical access is impossible.

3. Reduction in the use of chemicals
In most cases, a neutral, water-based detergent is sufficient. This minimizes the environmental impact and the risk of damaging sensitive lenses.

4. Time savings and increased productivity
The cleaning cycles are automatic and very fast, allowing multiple lenses to be cleaned simultaneously in just a few minutes.

5. Consistency and standardization
Each lens receives the same level of cleaning, without depending on the operator's manual skill.
