Thanks for the reply. I had checked the website earlier . But what I need is the formula for measuring accurate thickness.
How can I calculate exact center thicknessof a lens? Available datas are exact front curve, approximate back curve, lens power, lens index, tool index, diameter and edge thickness.
Beside from the programming side, I think my VCA request is not correct. I am expecting that if someone can suggest the right request.
Dave,
What I know is this tracer provides only binary differential format. It is fine if I can get the data in the same(3). It just need a decoding. But as you said, I am getting incomplete...
I am trying to develope a program to get the shape data from the tracer via RS232. I am using Visual Basic as the language.After sending the shape at first I am getting like below

Then I send...
This link is not available now! Could you please post the new link.
I have created a VB6 function to draw the shape on the screen from a VCA shape data. Its working fine with me. But there are some issues worrying me to go for the next level :) I would like to get...
Anybody has a remote tracer to sell? Preferred one is LT-900/LT-980/LT-1000/LT-1200.
I totally agree with your advise. This is how the situation should dealt.
Machines are connected through Rxpert and RxServer from Satisloh

Finally I fixed the issue :) I am sharing it here, it may be helpful for somebody in need.
It was a wrong setting of RxServer.
I changed the setting as follows in RxServer.

I think, I have to re-post my thread. It is not getting noticed.
Hi Experts,
We are unable to connect our V75 with Rx-Server, due to a communication error.
While we scan the bar code, most of the values are loading into V75 screen except the AVAL. Instead of...

Hi all
Please check the link below which I have created to check the lens thickness, diameter for SV lenses and lens comparison with CR-39. Please let me know if there is any error or anything need...
if the lens envelope shows 65/70; it means, geometrically the lens will be 65mm dia. But with 2.5mm decentration. So the effective diameter will be 70mm. (purpose: less material conception for the...
I dont think cost reducing is only the reason. I have noticed that for the lenses which is near to 90degre axis and plus powers are thinner if we make it in elliptical diameter.
elliptical means the lens will not be in round shape.
eg: normal lenses can be 65mm or 60mm diameter but elliptical will be 65/60 or 70/60
you can see it on this below pic.

Does the Elliptical lenses will reduce thickness? If it does, what is the logic behind it.:nerd:
can anybody advice?
:confused::mad:
We are using Satisloh PRA blocker since 7 years. Recently our surfacing technician has come up with a compliant that lens power variation is due to low temperature of the blocking ring area(blocking...
Is there any tinting machine available in market, which will scan the color and after mix the desired color by itself. I heard that one of the Chinese companies is the manufacturer of this...
What is the difference between antiglare coated lenses and ARC lenses. Please give me some brand examples.:confused:
