Hello,

We are having some problems with our Bayer Tester. Just wondered whether anyone out there has seen this before.

Our testing machine is quite old now and showing signs of wear. Instead of the carriage just going back and forth 600 times in 4 minutes, it jumps up and down a bit as it goes. All our results are down on what we used to get, and we do not really believe that this is because all our coating machines have developed problems at the same time. Cross checking coated lenses from other labs confirms that our results are coming out too low.

Apart from asking for a new Bayer Testing machine, can anyone suggest a work around, or a reason to explain what may be happening?

P.S. Lenses from the last batch showed strange patchy markings, apart from the usual haze.

Many thanks,

Falstaff
