Digitizing arms for metrology?

[Mstcnc]

Are there more brands of digitizing arms other than Faro and Romer?
Immersion ( Microscribe) do not manufacture arms anymore, they just sell until stock is empty...
What are options if one do not want spend $30K.

I just evaluated various arms and there is at least on more company:

Metris http://www.metris.com/

Metris is a Belgium metrology company that recently acquired the 3rd lagest arm manufacturer (an Italian company, sorry I forgot its name). There arm looks good to me and I think it can keep up with the other competitors. But it's it the >30k EUR range, at least the metrology grade model I evaluated.

Oh really? Hmm, I have a small Microscribe, I hope I will be able to get service for it if needed.

Hmm. About a year ago I looked around for a cheap arms but we then decided to wait a bit until we could spend >30k EUR on a pro solution, so I cant tell you much on low priced arms. All three companies sell used arms by the way, so maybe that's an option?

One company I remember is Zett Mess: http://www.zettmess.de/eng/ I don’t know technical specs nor how much they quote.

It depends on what you want to do. If you want high accuarcy then Faro and Romer are the only options you have for Arms. Microscribe and the other $30k options work but probably wont get better than .3mm. A Fusion arm from Faro is under $30k and it will do under .05mm. Romer depends on when you last placed it on a ballbar but it's in the same range.

Best advice, if it's in climate controled lab and never going to move a Romer is ok. If you want to use it on the manufacturing floor and move it around spend the money on a Faro.

If it's low accuarcy then there are some software packages that actually work with a 35mm camera. Probably in the $5k range and get .5mm or better.
