Konti Micro Stages – Modular

The Konti Micro Stages - Modular is a workhorse Konti Micro cryostat with modular upgrades such as closed-loop nm resolution piezo stages for movement of the sample, needle probes for making electrical contacts with the sample while cold, moveable internal optical objective holders for extremely low working distance, and internal moveable permanent magnets for localized magnetic fields, among others.
