Explore the World of Nano-Optics multichannel cryogenic confocal microscopes For many years, attocube systems has been pioneering cryogenic confocal microscopy. With the introduction of the attoCFM series of confocal microscopes almost a decade ago, the optical investigation of single quantum devices on the sub-micron scale at low temperature suddenly became available as a standard tool for scientists worldwide. Now once again, the attoCFM-MC is redefining the state-of-the-art for low temperature confocal microscopy. To improve the image quality in high resolution microscopy, confocal...

Stable. Modular. Easy to use. the all-new optical head from the pioneers of cryogenic confocal microscopy The novel multipurpose optical head provides an ideal platform for a large variety of measurement tasks in the field of confocal microscopy, while setting new standards for stability and ease-ofuse. At the heart of the optical head, there are up to three identical channels, which can be used for confocal excitation and detection of free-beam optical signals. Each channel features a FC/APC fiber port to connect to a laser source or an appropriate detector (such as a Si detector for...

attoCFM I low temperature confocal microscope, free-beam optics The attoCFM I has been developed to offer highest flexibility in order to enable adaptation of the experimental setup according to the customer‘s needs. This flexibility is realized by a modular beam splitter head which is positioned outside of the cryostat. Furthermore, the free-beam optical design allows a completely independent adjustment of the excitation and collection port. Therefore, applications such as Raman spectroscopy become accessible by appropriately filtering the excitation and collection signals. The easy...

your optical table goes cryogen free! The attoCFM-DRY is a low temperature compatible confocal microscope dedicated to perform cryogenic optical experiments on any optical table. The main concept of this development is to offer an ultra-high numerical aperture, apochromatic confocal table-top microscope dedicated for cryogen-free low temperature operation. To achieve this task, attocube has implemented a new apochromatic objective, providing an enhanced level of chromatic aberration correction with a numerical aperture (NA) of up to 0.95. As a result, ultra-high resolution images and...

Photoluminescence. Fluorescence selected applications for cryogenic confocal microscopy Confocal Microscopy on Quantum Dots at 50 mK Particularly, the observation of the optical transitions is the main tool to the basis for the application of quantum dots as laser emitters, storage devices or for quantum information processing. Semiconductor quantum dots have also been found to be attractive for the realization of spin quantum bits, as they can be controllably positioned, electronically coupled and embedded into active devices. These quantum bits represent the fundamental logical unit in a...
