Optical Cryostats for Microscopy
Efficient and cost-effective cryostats for optical microscopy.
Andor’s Microstat range of optical cryostats provide cryogenic sample environments with a variety of design and performance characteristics. Available as liquid Nitrogen and liquid Helium flow cryostats with sample-in-vacuum environment and sample temperatures from <2.2K to 500K. The Microstat range offers some of the most efficient and cost-effective cryostats for Optical Microscopy. They are equally suited to work in any orientation on an optical bench or integrated into a commercially available microscope.
➡️ Lowest cost of ownership – Helium cost calculator
➡️ Market leading low vibration and high stability options
➡️ Touch screen controllers with unique expansion capabilities
➡️ User upgradeable window flanges and controller channels
Microstat N
Compact nitrogen cooled
This cryostat has been designed for experiments requiring liquid nitrogen temperatures. It is very compact and lightweight and only requires a compact nitrogen container which is very convenient when space is limited.
➡️ Wide temperature range: from 77.2 K to 500 K
➡️ Extremely compact: 90 mm diameter by 24 mm thickness. Only 400 g
➡️ Economical use of cryogens: less than 0.5 L/h
➡️ Quick cooldown: 80 K in less than 10 minutes
➡️ Adjustable sample holders accommodate samples up to 8 mm thickness
➡️ Easy integration into commercial microscopes facilitated by its compact size and short working distance (as low as 3 mm). Interface plate available as option for attaching the MicrostatN directly onto microscope translation stage
➡️ Suitable for reflection and transmission experiments via choice of sample holders
➡️ Electrical measurements via 4-pin electrical feed wire to heat exchanger
Microstat He
Multi-experiments, helium cooled
This helium cryostat is well suited for experiments requiring a low temperature environment and which can evolve in the future due to its flexibility.
➡️ Wide temperature range: 2.2 K to 500 K
➡️ Easy integration into commercial microscopes facilitated by its compact size and short working distance (as low as 4.5 mm). Interface plate available as option for attaching the MicrostatHe directly onto microscope translation stage
➡️ Economical use of cryogens: the lowest consumption on the market using only 0.45 l/hr at 4.2 K
➡️ Rapid cooldown time: 4.2 K in less than 10 minutes!
➡️ Suitable for reflection and transmission experiments via choice of sample holders
➡️ Adjustable working distance via sample holder. Can be adjusted to less than 3 mm
➡️ Interchangeable tail between the OptistatCF-V, MicrostatHe, and MicrostatHe-R with rectangular tail
➡️ Can be used with liquid nitrogen
➡️ Electrical measurements via 10-pin electrical feed wire to heat exchanger. Optional coaxial cables
Microstat HiRes
The lowest vibration microscopy cryostat on the market
This cryostat has been designed to minimise vibration and sample drift at stable and constant temperatures. This is achieved by cooling the sample on a stable cold platform rather than a cold finger and feeding the helium to the heat exchanger via a capillary, thus isolating the helium flow vibration. The MicrostatHiRes is particularly well suited to sensitive applications such as microphotoluminescence mapping of semiconductor microstructures with sub-micron spatial resolution.
➡️ Wide temperature range: from 2.7 K to 500 K
➡️ Low sample drift: 0.15 µm per hour (typical) at 4.2 K enabling measurements over many hours. 13 µm (typical) cooling from 300 K to 4.2 K
➡️ Low sample vibration: < 20 nm typical
➡️ Extremely short working distance of 2.2 mm enabling the use of high magnification optics
➡️ Adjustable top flange (3.5 mm adjustable distance) enabling samples of different thicknesses
➡️ Rapid cooldown time: 4.2 K in less than 15 minutes!
➡️ Easy integration into commercial microscopes facilitated by its compact size. Only 90 mm diameter by 45 mm thickness. Lightweight 1.5 kg only
➡️ Economical use of cryogens: the lowest consumption on the market using only 0.7 l/hr at 4.2 K
➡️ Suitable for reflection and transmission experiments via choice of sample holders
➡️ Experimental flexibility: may be operated in any orientation
➡️ Electrical measurements via 10-pin electrical feed wire to heat exchanger. Optional coaxial cables
