Confovis Introduces Portal Measuring System For Optical Lenses

(Nanowerk News) confovis, the specialist in 3D surface inspection, has expanded its portfolio by introducing a measuring system for the optical industry. The portal system with its positioning unit allows fast non-contact quality inspection of the surface integrity of optical lenses down to the nanometer range. It enables free rotation and swivelling of the optical surface. In this way the system detects the height, depth, width, radii and angles of flaws at any point on the lens and generates informative 3D analyses, also of reflective surfaces.
The confovis system was specially developed for the high quality requirements in the optical industry. Lenses must be checked for scratches, particles and inclusions to be able to determine their quality and subsequent use. Combined with Nikon microscope components and the ConfocamC1+ confocal scan head, the portal allows reliable and high-precision measurements and informative 3D analyses. If required, the system can also be equipped with extra-long working distance objectives. Besides the 3D analysis, the positioning unit also provides a transmitted light function for classic 2D observation.

High-precision measurements in the nanometer range The confovis measuring system measures and analyzes the height, depth, width, radii, and angles of lenses down to the nanometer range with the highest precision and is also suitable for reflective surfaces. The non-destructive optical test method allows classification of the lenses by fault, so these can then be refinished or discarded accordingly.
The positioning unit for 5-axis positioning enables the optical surface to be swiveled and rotated. To do this, the lens to be tested is fixed in a clamping device and positioned flexibly with the positioning unit. Any required point on the sample can be measured in this way without any great effort.
Flexibility meets ease of operation
Just like all portal solutions by confovis, the portal for optical lens inspection provides the highest degree of flexibility concerning the working distance, so all kinds of sample heights can be measured using one measuring device. The vibration-cushioned subframe guarantees high-precision measuring results.
