Infinity Light

Add light to your Climate or Stream Infinity system

The Climate and Stream Infinity systems now offer advanced optical capabilities. A new optomechanical tip brings light straight into the multi-stimuli holder, so you can illuminate your specimen while applying electrothermal stimuli in both gas and liquid environments.

Light - alongside the stimuli you already control

Infinity Light adds an optical path to the Infinity sample holder, so illumination becomes one more parameter of your in situ experiment instead of a separate one.

01

Simultaneous multi-stimuli

Introduce light to illuminate your specimen directly while applying electrothermal stimuli in gas and liquid environments. Illumination combines with gas or liquid flow, heating and biasing in the same experiment, so you can tell what the light does apart from what temperature and potential do.

Unlock new applications

Ideal for advancing photo-electrochemical, photocatalysis and solar cell operando research. Reactions that only start under illumination can now be followed at the nanoscale, in the gas or liquid environment where they actually happen.

A convenient upgrade

Current owners of the Infinity sample holder can upgrade to the new optomechanical tip without compromising the performance of their Infinity system. The optical fibre is integrated into the tip and ends at the sample window, and the eight electrical contacts for heating and biasing stay exactly as they are.
