Cryospot™ Cryogenic Systems
Photon Spot offers a number of cryogenic systems that can be further tailored for your experimental purposes. Our cryogenic systems:
- require no prior cryogenic experience to operate,
- are closed-cycle, meaning they do not consume liquid cryogens for operation,
- can be configured with one of our sorption fridges to enable < 0.8K operation, and
- have a very compact form-factor, yet provide a sample space that is sufficient for most low-temperature experiments.
Our cryostats are perfectly suited for superconducting detectors, such as superconducting nanowire single-photon detectors, and cryogenic electronics including resonators and RF/microwave mixers. Their fast cooldown times also make them perfect for "rapid" component testing, and critical current/temperature measurements.
Cryospot 5The Cryospot 5 is our newest cryogenic system with the largest sample volume. The Cryospot 5 is designed to accept either GM or PT cold heads, can take 2 sorption fridges, and offers free-space optical access. The Cryospot 5 can support up to 64 detector channels. |
 |
Cryospot 4FSThe Cryospot 4FS adds free-space optical access to our popular Cryospot 4 cryogenic system. The Cryospot 4FS can also be configured with a pulse-tube cooler for lower vibrations. |
 |
Cryospot 4The Cryospot 4 is our most versatile cryogenic system. The Cryospot 4 is designed to accept GM cryocoolers of a variety of sizes (up to 1W @ 4.2K), and is ideal when vibrations are not an issue. The Cryospot 4 can support up to 16 detector channels, and can be extended to support 32 channels. |
 |
Cryospot 4MThe Cryospot 4M is our entry-level cryogenic system and is also the most compact. Due to its size, the Cryospot 4M can only be configured with a 0.1W/0.2W GM cryocooler. The Cryospot 4M can support up to 4 detector channels, and can be extended to support 16 channels. |
 |
Cryospot 4LVThe Cryospot 4LV is our low-vibration cryogenic system and comes equipped with either a 0.25W or 0.5W pulse-tube cooler. |
 |
Cryospot 3 (discontinued; by special order only)The Cryospot™ 3 is our cryogenic system with the largest sample space. The Cryospot 3 is designed to fit GM or pulse-tube cryocoolers, air- or water-cooled compressors, and a rack of supporting electronics in its frame. |

0.8K Sorption Fridges
Each Cryospot system can be ordered with a 0.8K Helium sorption fridge. Our sorption fridges typically hit a base temperature between 0.7K -0.8K. Our patent-pending technology behind the sorption fridge enables fast cooldowns, rapid cycle times, and a stable temperature.
Freeze4™ 0.8K "Single-Shot" Sorption FridgeThe Freeze4 helium sorption fridge enables operation at 0.8K and below at the touch of a button for a hold-time of 12 hours, 24 hours or 36+ hours, depending on the model. |
 |
Freeze4-XT Continuous Sorption FridgeThe Freeze4-XT enables continuous operation at sub-Kelvin temperatures. |
Software & Options
FreezeControl SoftwareThe FreezeControl™ software application allows automated operation of our Cryospot systems. Each of our systems comes standard this software, with free updates as new features are added. |
 |
Vacuum & Remote Control PackageThis option is recommended for users who wish to operate the cryostat from a remote location, or for users with limited or no prior cryogenics experience. We provide an oil-free roughing/turbo vacuum pumping system, vacuum gauge, and control electronics for remote on/off of the helium compressor, vacuum pump, and vacuum valve. All components are monitored and controlled via the FreezeControl software. |
