Cleaning is the basis for flawless quality

In the manufacturing of ophthalmic lenses, it is crucial that each process step fulfils the highest cleanliness requirements and that no impurities are carried over. We have analysed these processes in detail and identified the process steps in which the highest cleaning requirements must be met in order to achieve optimum results.
Cleaning requirements

We specialise in the cleaning of glass moulds as well as cleaning between the various stages of lens production, particularly before hard coating (HC) anti-reflective (AR) coating.

HC and AR coating are the most cost-intensive steps in the entire lens production process, so ensuring the highest surface cleanliness and hard coating adhesion by activation of the surface is crucial. Our focus on purity and quality guarantees you clear and brilliant results ensuring that your ophthalmic lenses not only meet the highest standards, but also increase the cost efficiency of your entire production and fully fulfil the quality requirements of your customers.

deconex® OP cleaning solutions for every stage of production

The products in the deconex® OP line have been specially developed for use in pre-cleaning ready for inspection and in fine cleaning ready for coating. Here they are used for the removal of

  • polishing pastes
  • colour markings
  • lacquers
  • protective film residues
  • fingerprints
  • dust and all kinds of particles

We also offer a customised solution for coating defects with the deconex® de-coat product line. The decoating solutions efficiently and effectively remove defective anti-reflective and hard coating layers ready for recoating. Our experts also support you in cleaning spectacle frames as well as glass moulds and thermoplastics.

Our solutions in the manufacturing process for ophthalmic and sunglass lenses

In order to ensure consistent quality and precision of the manufactured parts, the correct cleaning and decoating steps are of crucial importance in ophthalmic lens production.

In our deconex® portfolio you will find suitable products for every application in the cleaning and decoating of ophthalmic and sunglass lenses.

Meticulous purity in optoelectronics

The production of optoelectronics demands the utmost precision to guarantee excellent quality and performance, meeting the standards of modern technology. Ensuring that no impurities or particles remain on the surface of the lenses or on the cover slips is essential, as even the slightest particles could substantially hinder the optics’ performance.

Our tried-and-tested deconex® cleaning solutions have been specially developed to remove precisely this type of contamination. They are used, for example, in the cleaning of cover slips used in the production of image sensors.

Four steps to reproducible cleaning 
results:

1. Cleaning the bare glass after machining
After the glass has been cut, ground and polished, careful cleaning is necessary to remove all production residues and impurities.

2. Cleaning the bare glass before AR coating
Before applying the anti-reflective coating, the glass is cleaned again to ensure that the coating adheres to a clean surface.

3. Cleaning AR-coated glass before dam coating and after structuring
The AR-coated glass undergoes further cleaning steps to maintain cleanliness during the complex production processes.

4. Cleaning AR and dam-coated glass before attaching the silicon sensor
This step is crucial to ensure that the sensor chip encounters a perfectly clean surface.

At the end of the manufacturing process, the cleaned cover slip with AR and dam coating is precisely applied to the sensor and then cut into individual modules.

The primary objective when inspecting the cover slip after cleaning is to ensure that no particles or residues > 5 μm in size are present. Such particles could impair the incidence of light in the sensor chip, leading to deflections or unwanted reflections of the light. This reduces the amount of light transmitted to the sensor component and results in a lower resolution.
