Recomendations on Finish blocker
Hi all,
I'm in the market for a new OMA compliant finish blocker that is fast, simple, and above all extremly accurate. Olny thing I've seen is Gerbers Step 2. And I have no idea how well it perfoms with reguards to "twist" (happens to be my biggest problem)
Any thoughts???:confused:

The Step Two, having been designed prioir to the development of the OMA (now VCA) Data Communications Standard, is not "OMA-compliant".
If you want an OMA-compliant finish blocker at the moment, you have to take something else with it: the Weco Verifier (which is a combination lensmeter-blocker) and the GC Kappa tracer/blocker are the only OMA-compliant finish blockers I know of.
GC will be introducing something that I can't tell you about at Vision Expo West, which may be of interest (and which will be OMA-compliant).
The Step Two, with its thermoplastic adhesive "freeblocks", does provide quantifiably superior resistance to slippage compared to adhesive pads.
