V C T VCPN VISIONCAREPRODUCTS.COM 92 // APRIL 2016 the need for a shelf bevel and the place- ment of notches and grooves if neces- sary. They do all this with the gear- driven accuracy of a Swiss watch. A great example is the Santinelli XtremeD LT-980 and LT-1200 Trac- ers. Among the characteristics that make them unique is the fact that these tracers use half of the stylus "pressure to frame" of previous generation trac- ers. This results in less distortion of eyewire shapes, even on the most fex- ible frames. The use of tungsten car- bide on its uniquely shaped stylus tip provides a friction-free gliding action during a tracing cycle, which is anoth- er reason for its accuracy. COMBINED FUNCTIONS Many new "tracers" are often com- bined with other lab-processing fea- tures such as lensometry, layout and blocking. Since these functions are so relative to each other, it makes sense to combine them and reduce the amount of time it takes to physically handle a lens. The Coburn HAB-8000 Exxpert Automatic Lens Tracer/Blocker is one of these machines. Enter the frame and measurements, trace the frame, take a digital image of the shape, place an uncut blank on the prescription-ver- ifying table, touch "start," and let the "Exxpert" do the rest. It is so accurate, it can identify where to place holes and slots for drilling, and it can automatically detect all lens types, such as single vision, progres- sives and bifocals. There is no need to "dot up" single vision lenses. Thou- sands of jobs can be saved on the SD card, either numerically or by cus- tomer name. You only touched the lens once, so the amount of time you'll save is an important beneft when in- corporating these machines into your practice. The HAB-8000 can be used with all of Coburn Exxpert and Exce- lon edgers or as a stand-alone unit in a lab environment with a lens-ordering connection available. TRACING WITHOUT A STYLUS Stylus-free shape recognition is now possible with the use of digital camera imaging. The Mei Shape Finder 2.0 is just one example of this type of tracer. The Shape Finder 2.0 differentiates itself from other camera-based units with its unique use of multiple camera lenses and an internal lighting system. The purpose behind this technology is to eliminate the perspective effects of feld distortion and provide a per- With stylus-free shape recognition, the Mei Shape Finder 2.0 sets itself apart with multiple camera lenses and an internal lighting system. system you will be able to mill those popular wrapped notch-and-hook, shelf-beveled shapes that are typically sent out to frame manufacturers for processing. The Weco C.6 Auto Blocker also traces without a stylus. With wave- If you own a tracer or are considering the purchase of one, you can make them perform better if you understand what makes them tick. Its integrated wavefront power mapping lensometry allows the Weco C.6 Auto Blocker operator to make sure that the shape will work by superimposing it directly onto a contour power map of a PAL. fect edge profle. The Shape Finder 2.0 will eliminate the need for "test lenses" when shelf beveling, notch- ing and drilling because it can create a precise OMA protocol fle in just a few steps. When paired with a Mei edging front power mapping lensometry integrated into this retail blocker, the unit allows you to superimpose the shape directly onto a contour power map of a progressive lens, verifying for the operator that the shape is go-
