ZEISS HFA2i 740i 745i 750i Humphrey visual field chinrest assembly complete with trial lens holder.

Is your trial lens holder broken? Chinrest part broken?

This is a part for the technically inclined. if you need a quick swap check out my other listing.

For the price of a trial lens holder you get the complete chinrest assembly and you can do it yourself in 10 minutes.

I can provide instructions on how to swap it. (7 screws, Allen 3 mm)

The trial lens holders are not available from Zeiss anymore. You can't buy one.

This is a way to extend the life of your instrument.

If the shipping quote doesn't look right let me know and I will check for the best way to get this to you.
