Blockless edging system

Based on proven ES-4 technology, Satisloh´s fully automated blockless edger, the ES-5, edges ophthalmic lenses without block-pieces and adhesive pads. This improves production flow, saves time and costs by eliminating lens preparation and post-processing steps as well as consumables.

Wet cutting technology creates unsurpassed edge quality and exceptionally long tool lifetime, reducing the frequency of tool changes and calibration.

An integrated lens inspection system, LIS, checks Rx power and cut-out of lenses, eliminating additional inspection steps prior to edging. The ES-5 easily detects and inspects even low powered single vision and prismatic lenses, ensuring precise decentration for all lenses.
