Briot Attitude Evolution

The core duo for your workshop

The Briot Attitude Evolution Combo plays a crucial role in the workflow of your optical lab by ensuring fast and incredibly reliable results via state-of-the-art shape reproduction processes such as TrueScan and GraviTech®. These technologies ensure accurate dimensions and an unparalleled automatic blocking process with superior lens edging, thanks to Briot’s exclusive Torque Management System (TMS).

Exclusive TrueScan High-Curve Tracing

Featuring our patented TrueScan technology, the Attitude Tracer/Blocker has a specially designed angled probe that will gently measure the contour of even the thinnest, most delicate metal frames or high base-curve wrap frames effortlessly.

Easy Shape Creation, Repair, and Modification

Never before has it been easier to do complex shapes, drill mount work, and shape repair.

Wavefront, the future of blocking

Our exclusive wavefront lens analysis allows you to see progressive lens designs on the frame trace before you even cut the lens, giving you the opportunity to validate that the shape and lens design are compatible without wasting time or money redoing the job.

Brushless Technology for Faster, Quieter Operation

Edge lenses faster and more efficiently while also reducing noise with new brusheless motor technology featured on the Evolution. Now, you can plug this edger in anywhere that has a 120V line adding extra placement flexibility in your optical lab.

Provide the Best Finish on High Base-curve Frames with Briot’s Best-Fit Technology

Our advanced drive technology in conjunction with a small 90mm diamond wheel allows flawless finishing on high base-curve lenses and complex frames with sharp corners.

Damaged Demo Lens? No Problem with Shape Creator 2.0

The Evolution can accurately reconstruct broken or defective demo lenses with minimal effort using the new Shape Creator 2.0 technology on the Evolution Blocker.
