It can be placed as close as 200 mm to the long edge, as well as off-center with respect to the short edge on wider tables (depending on table size). Contact attocube for more details. Ultra-short working distance A popular option for flow cryostats is to bring the cold sample as close as possi- ble to an ultra-low working distance window. This allows to flexibly use external optics with a very high angle of admittance, maximizing the collection efficiency via high numerical aperture objectives. The ultra-short working distance option (RT-USWD) is compatible with xyz positioners and xy scanner, and features a min. working distance of 2 mm (1 mm) with (without) cold window installed.
