3993/JN/23 - Closed-Cycle Cryostat System (2 Lots)

Tender description

The University of Sheffield's department of Physics and Astronomy are looking to procure 2 types of closed-cycle cryostat systems for optical spectroscopy of semiconductor quantum dots (QDs). Lot 1 - Optical Table Cryostat for Photoluminescence Imaging: A closed-cycle cryostat system is required for optical spectroscopy of semiconductor quantum dots (QDs). The principal uses will be for micro-photoluminescence and photoluminescence imaging from self- assembled InGaAs QDs in the Department of Physics and Astronomy. Lot 2 - Standalone Optical Cryostat for Long Duration Measurements: Up to 2 closed-cycle cryostat systems are required for optical spectroscopy of semiconductor quantum dots (QDs). The principal use will be for micro-photoluminescence measurements of self- assembled InGaAs QDs in the Department of Physics and Astronomy, in particular long-duration measurements under resonant laser excitation that require very high stability and low vibration. This is an FTS open exercise.
