Diacell® ST-DAC System

Optical micro-spectroscopy, Cryostat with integrated DAC, Pmax = 20 GPa, Tmin = 3.5 K, WD = 11 mm
  • The Diacell® ST-DAC consists of a Janis ST-500 continuous flow cryostat with an integrated CryoDAC-ST diamond anvil cell (DAC)
  • The system enables high pressure studies up to 20 GPa and temperatures down to 3.5 K
  • The system is a turn-key solution for microscopy, imaging, and high spatial resolution photoluminescence at high pressures and low temperatures
  • The cryostat combines low thermal expansion support structure and internal vibration isolation resulting in nanometre scale vibration and drift levels
  • The geometry offers a short working distance (for use with high magnification optics), and permits mounting on common microscope stages and translators
  • Recommended option: a temperature controller

Description

High pressure microscopy cryostat, the Diacell® ST-DAC System consists of a Janis ST-500 continuous flow cryostat with an integrated CryoDAC-ST diamond anvil cell. The system is a turn-key solution for microscopy, imaging, and high spatial resolution photoluminescence at low temperatures and high pressures.

The cryostat combines low thermal-expansion support structure and internal vibration isolation resulting in nanometer scale vibration and drift levels. The geometry offers a short working distance (for use with high magnification optics), and permits mounting on common microscope stages and translators.

Options for the Diacell® ST-DAC System include a temperature controller with cable to cryostat.
