The Tucsen sCMOS Dhyana400D camera has been used by Dr Ilya Beterov, a Senior researcher at the Rzhanov Institute of Semiconductor Physics, from the Siberian Branch of the Russian Academy of Sciences in his research program exploring aspects of quantum computing.
He uses the Tucsen camera as part of an experiment designed to trap, isolate and detect single Rubidium atoms in an optical dipole trap.
sCMOS cameras like the Dhyana 400D offer much more affordable alternatives to expensive EMCCD cameras. In a recent paper (see link below), he reported: 'In this paper, we present our recent experimental results [8] on demonstrating the trapping of single 87Rb atoms using a long-focus objective lens with a numerical aperture NA = 0.172 placed outside the MOT vacuum chamber and detecting single atoms with a lower-cost sCMOS camera at a short exposure time (50-200 ms).'
An interview with Dr Beterov on quantum computing and related topics, including a tour of his laboratory and several views of the Tucsen camera, was recently conducted by Russian youtube channel Just Science.

Video description: At the moment, there is a real race between public and private corporations to create the world's most powerful quantum computer. Why is this topic so relevant? How is a quantum computer different from an ordinary computer? How will our life change with the development of this technology? Ilya Beterov, an employee of the IPP SB RAS, will answer these questions and show a setup for a quantum computer with ultracold Rb atoms.
The Tucsen camera appears at 18:26.
Tucsen Photonics Dhyana 400D sCMOS Camera is equipped with a brand new 1.2 inch scientific CMOS sensor, which provide 80% quantum efficiency at 600nm. The 1.2 inch sensor size and 6.5X6.5um pixel size is more suitable for microscopy standard C-mount imaging.
When comparing to other existing scientific CMOS camera products, Dhyana 400D has a hardware 2X2 binning function which provides superior sensitivity for low light imaging.
Dhyana 400D has advantages of FOV, extremely low noise, high dynamic range, and high frame rate, and more over. In addition to the standard monochrome version, the Dhyana 400D is also available with a colour sensor.
