Do optical impairments occur?
Our procedures exclude or minimize optical impairments in the sense of distortion. Our method is used to create the transition from the surface to be treated to the untreated area in such a way that distortions in the transition are prevented.
As a rule, the processing of the glass is not visible or disturbing for the normal observer and thus complies with the guidelines for assessing the visual quality of glass for the building industry.
The guidelines specify, for example, for ESG:"The local ripple on the glass surface [...] must not exceed 3 mm in relation to a measuring distance of 300 mm".
As mentioned above, our usual machining area is usually between 0.02 mm and 0.05 mm.
In case of damage close to the edge, it may only be possible to work by hand. This does not always result in a complete remediation, but a significant improvement and minimization of the damage is achieved.
In most cases, these areas are subject to less stringent requirements for the building industry in accordance with the Guideline for the Assessment of the Visual Quality of Glass, and are generally subject to less stringent requirements.
