Acquisition of a closed-cycle cryostat to Quantum Photonics Group, Niels Bohr Institute

We are purchasing two closed-cycle cryostats, dedicated to quantum photonics experiments. These experiments require stability on the nanometer scale, temperatures at 4 K to suppress all decoherence processes, fiber access to the samples, vector magnets, and RF and feedthroughs for low-noise operation of quantum emitters. Both systems need to operate in the 600nm – 1100 nm wavelength range. Additionally, one system requires to be compatible with operating at O-band wavelengths (1200nm - 1350nm). The supplier shall install the system on-site and train local personnel in using the cryostat systems.
