Looking in labs: Manufacturing lenses - part 2

Satisloh

Satisloh currently has two lines of lens generators the VFT-Orbit 2, which is automated for big labs, and the VFT-macro, which is manual for medium and small sized labs. The VFT-Orbit 2 is the company’s high volume flagship which processes all organic lens materials and generates up to 110 lenses per hour.

The machine is said to raise the bar set by the original VFT-orbit with greatly improved performance, throughput, quality and reliability. Key enhancements include a new ultra-fast milling spindle for cribbing, rough surfacing to reduce the blank’s size that increases throughput by up to 30%, a proprietary milling tool interface for 14-tooth cutter which enables 60% higher revolution speed, and a VFT fast tool for surface accuracy and smoothness.

The VFT-macro generator is for free-form and Rx lens production and produces up to 50 lenses per hour. This manual compact generator is said to meet all requirements for high quality digital lens production while setting the standard for cost efficiency.
