Mini-kappa MK3

The MiniKappa, MK3, is an easy to mount/dismount goniometer head which offers an additional kappa and phi axis. This gives numerous possibilities of crystal re-orientation in a fast and easy way.

Together with the software package STAC the MK3 allows setting up crystal alignment strategies which lead to more efficient x-ray data collection  (Brockhauser, 2013).

(κ) Kappa:

-        Rotational precision:  ±0.05°

-        Travel Range: 0 to 255°

-        Resolution: 0.35 mdeg

(ϕ) Phi:

-        Rotational precision:  ±0.09°

-        Resolution: 1.41 mdeg

(Χ) Chi axis:

-        Travel Range: 0 to 48°. Value depends of the kappa-axis' position.
