Description

A Dedicated tool for aspheric and freeform optics metrology

  • Non-contact
  • High Accuracy (<100nm)
  • Sub-micron lateral resolution
  • No prior knowledge of nominal sample shape required

The versatile PLu apex is able to measure any optical surface, from aspheric to flat surfaces, machined and freeform optics, molded optics and even the molds themselves. Its innovative design – based on Sensofar’s core technology, confocal metrology – allows a non-contact and high-precision measurement. Not limited by the shape of the sample, independent of sample reflectivity, and suitable for circular or rectangular shapes.

The PLu apex is equipped with a high-precision XY crossed-roller bearings stage and powerful aspheric curve analysis software as well as a fast, easy to use sample alignment technology.

The Apex is able to meet the most demanding metrology requirements for large samples with an XY measurement range up to 100×100 mm, up to 50 mm Z measurement range and up to 65º slope angle.

Non-contact metrology plays a key role in aspheric and free-form optics manufacturing industries. This holds true for mass production of Blu-ray and DVD lenses, cellphone, PDA camera lenses, digital cameras, projectors lenses. It is especially critical for high precision applications such as astronomical instrumentation, optical data storage and photolithography.

Applications
  • Machined optics and molds
