• For optical thermal microscopy and spectroscopy

  • -190°C to 400°C with liquid nitrogen cooling option

  • Large 38 mm × 50 mm sample area

  • XY sample positioning

  • Sealed chamber with gas purging capability


TheHCS302GXY features a gas-tight sample chamber which can be gas purged to prevent condensation or to make measurements under a controlled atmosphere and at a set temperature. Top and bottom dual pane windows on the HCS302GXY stage are removable and exchangeable to meet a range of spectroscopic needs. The stage can be mounted vertically, allowing horizontal beam access to the sample chamber. An inner thermal cover is also included for work requiring ultra-high temperature stability.

The HCS302GXY is a versatile and budget-friendly option for experiments requiring atmospheric control.
