Agile Temperature Stage –
No drift from 4 K to 350 K

Does your low temperature application require precise positioning and thermal stability? The Agile Temperature Stage from Montana Instruments was developed to suit your needs. A temperature change during optical measurements with high numerical aperture (NA) often leads to a loss of focus due to drift or a shift of the interesting structures on the sample into areas outside the imaging area.
The Agile Temperature Stage is an integrated device that combines a variety of technologies in one system.
A unique suspension design optimizes the mechanical stability and stiffness and provides the thermal performance necessary for rapid temperature changes. The suspended structure reduces thermal contraction to < 30 µm over the entire temperature range from 4 to 350 K.
This eliminates the need to re-focus after small temperature changes and guarantees stability of the optimized focus even throughout longer measurement times.
