ctc7-hozf2_0

IR Cryostat with PGA (pin grid array) ZIF (zero insertion force) socket is both a side looker and a down looker

 ctc7-hozf2_0 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
  • ctc7-vert1Flanges 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
  • Windows are to tilted off axis by about 6 (+/-2) degrees
  • Copper, Field Baffle and cold shield
  • Sample Mounting block with heater and temperature sensor to match standard temperature controllers
  • Sample Space can be pumped to a vacuum of 10-7 torr
  • All joints and seals to be helium leak tested to 1×10-8 Std. c.c./sec
  • Other items included:
    • 25/50 watt Heater
    • all wires and connectors to the sample socket
    • all wires and connections to the temperature controller
    • 25 Phosphor Bronze wire connections to the sample socket
  • Basic manual for Assembly and use of cryostat
  • A drawing will be sent to you for your approval before manufacturing begins.
