IR Cryostat with PGA (pin grid array) ZIF (zero insertion force) socket is both a side looker and a down looker
System Specifications:
- LN2 dewar for IR detector with PGA ZIF socket.
- Dewar is both a side looker and a down looker
- The side looking can occur along one axis in order to keep the LN2 in the reservoir.
- The system can be used in both orientations, changing from one to another can be accomplished reliably and quickly.
- Variable Temperature Range of 69.5K to 400K, Indirect sample cooling by cryogen
- Non-magnetic materials will be used through-out the design
- Main Dewar, 1-2 liter cryogen capacity, approximate. dimensions 4 in. OD tail , 8 in. OD main body x about 20 in. long
- Main Dewar will hold sample at below 80K for more than 3 hours in horizontal or vertical position
- Vacuum port valve with KF flange, NW-10
- Cryogen fill/vent port KF flange, NW-25
Flanges for electrical feed-throughs, supplied with mate, Qty 2
- 1 with 15 pin sub-min D for temperature sensor and heater connections
- 1 with 25 pin sub-min D for connection to grid array socket- others types optional
- Tail Section with window, 1 inch dia. clear, mounted in end of tail section
- Windows are to ZnSe or KRS-5 and transparent+/-5% to wavelengths of 10-20 microns
- Windows are to be sealable with o-ring or indium seals
