Hi Group,

 

Does anyone know why absolute encoders cost $6,000 on the ME2 mount?

 

Has anyone installed their own encoders?

 

Thanks

John

Encoder rings are not cheep..  +/- 5 arc sec encoder rings are 1k each on  e-bay

Almost never see the high end +/- 1 arc sec rings there and when they do show up they don't last long.

Read heads run $300-400.00 each

Interface cards run $280.00 each

1) The cost of the encoders (each axis) are $2000+ each assuming they are from Renishaw

 

2) You would have to know the exact model of Renishaw encoder and encoder ring, and they would cost you $4000+ to buy, and you would not have any warranty

I actually have a quote from Renishaw.

 

The 75mm RESM ring with 40um gradations is US$ 610.

 

The Quantic encoder with 200X interpolation (and it is a relative encoder) is US$ 703.

 

Plus taxes and S/H. And that's for a relative encoder. Am sure the Paramount uses a larger than 75mm ring.
