attoCFM-DRY
:.........................................................................................
pulse tube cooler system confocal microscope
The latest development of attocube is the new pulse tube cooler
based confocal microscope attoCFM-DRY. The main concept of this
development is to offer a table-top system which can be mounted
onto any size of optical table, allowing fast, highly accurate, and
stable confocal measurements. The dual-stage pulse tube cooler integrates
a novel anti-vibration system, which facilitates highly sensitive
measurements in a cryogen-free environment. Together with the custom-made radiation shield, the outer vacuum case and an
exchangeable optical window, easy integration with existing optical
setups is enabled.
Further features such as easy sample exchange, fast cooldown
and turn-around times, and simple operation guarantee
customer satisfaction and successful experiments.
Principle - attocube‘s attoDRY700 is a two stage pulse-tube cooler
reaching a temperature of 65 K at its first stage and 2.8 K at its second.
With 10 W cooling power at 65 K and 250 mW at 4.2 K, the
attoDRY700 offers sufficient cooling power for very fast turnaround
times. In addition, attocube‘s pulse tube cooler offers most reliable,
lowest vibration cooling to < 4 K of any product on the market
today.

The basic system includes the following components
|
low vibration pulse tube cooler including a low
tempearature compatible lense and xyz
coarse positioning unit. |
|
built-in anti-vibration system enabling high resolution confocal
imaging. |

Options
|
NEW: Apochromatic, high NA objective:
|
| |
attocube‘s latest development is the new series of apochromatic
objectives, which provide an enhanced level of chromatic
aberration correction for low temperature confocal microscopy.
These objectives are available with 50x and 100x magnification
and feature a numerical aperture (NA) of up to 0.95. As a result,
highly resolved images and spectra with high collection efficiency
can be obtained making this objective series ideal for low
temperature cryogen-free experiments on e.g. quantum dots,
photonic crystals or NV colour centers in diamond. Request more information. |

| Customer Feedback
|
| Dr. Bernhard Urbaszek |
 |
(INSA Genie Physique, Toulouse). |
We are pleased with the performance of the attoDRY700. The good mechanical and thermal stability ensures that overnight the selected quantum dot remains within the focus of the objective. |
