Optical Heating and Cooling Stage ACH600S-XY/ACH400SV-XY
Product Detail
InSitu Pro™ ACH600S-XY and ACH400SV-XY add precision sample positioning to the LN₂ optical family: an XY-adjustable stage with ±6 mm travel and 0.01 mm accuracy, so you can move between regions of interest, map across a sample, or re-center a feature during a run — without touching the microscope. The same −190 °C to 600 °C engine (ACH400SV-XY: to 400 °C in vacuum), ±0.1 °C stability, in a 21.5 mm-tall body.
Key features
- XY positioning: ±6 mm, 0.01 mm accuracyMove the sample under the objective instead of the stage under the sample — visit multiple grains, devices, or flakes, map temperature-dependent behavior across a surface, and keep a feature centered as it drifts.
- Full −190 to 600 °C in one stageLiquid-nitrogen cooling and resistive heating in the same body; heating and cooling branches of a transition measured on one sample, one instrument.
- ±0.1 °C with three control modesFixed-point, ramp, and multi-segment programmable profiles; the provided LabVIEW VIs / C# SDK support customized programming.
- Reflection and transmission opticsHand-removable JGS2 quartz windows and a through-hole silver stage support both light paths; a twist-off top cover makes sample loading and removal quick — full geometry in the table below.
- Light, thin and compactSame 21.5 mm height class as the ultra-thin T variants; the 155 mm length houses the XY mechanism while the body adapts to optical instruments of different brands and models.
- Choose your atmosphereACH600S-XY runs in an atmosphere chamber for the fastest workflow; ACH400SV-XY adds a vacuum chamber that suppresses oxidation during measurements (see the simulator below for why that matters).

Plan your cooling run
Both XY models cool with liquid nitrogen at up to 40 °C·min⁻¹ down to −190 °C. Set your target below and see how LN₂ compares with Peltier stages and passive cooling — and how long a run to your temperature actually takes.
Model: controller-limited linear ramp with a Newton-type approach near each technology's floor. Takeaway: below −25 °C, LN₂ is the only option — exactly what this stage family provides. Curves are schematic family-level behavior, not a guarantee for a specific unit.
Why the vacuum model? · ACH400SV-XY
Above a few hundred °C in air or another oxidizing atmosphere, oxide growth on many metals and alloys becomes significant, rising steeply with temperature; under diffusion-controlled conditions it is often approximated by parabolic kinetics. Hold a sample for an hour at your working temperature and compare the two chambers:
Model: parabolic oxidation x² = k·t with an Arrhenius rate constant — an approximation for diffusion-controlled oxidation, not every material or temperature; the vacuum panel suppresses the oxidant supply. Takeaway: if your sample must come back chemically intact from high temperature, reach for the vacuum chamber of the ACH400SV-XY.

FAQ
XY variant or standard — which one?
Pick by workflow. If you measure one spot per run, the standard ACH600S/ACH400SV is simpler and shorter. If you need to visit several regions, map behavior across a sample, or re-center a feature that drifts with thermal expansion, the XY stage's ±6 mm travel at 0.01 mm accuracy does it without disturbing your optics. Temperature performance is identical across the family.
What can I do with ±6 mm of travel?
A ±6 mm travel gives a 12 × 12 mm accessible window around center — enough to hop between multiple flakes or devices on one chip, follow a phase front, or build a coarse temperature-dependent map, with 0.01 mm positioning accuracy.
How does the geometry differ from the other variants?
The body keeps the low 21.5 mm height of the T variants but runs 155 mm long to house the XY mechanism; the top window sits 5.1 mm above the sample surface with a 4.8 mm chamber height. Check lateral space on your microscope stage plate.
Which atmosphere should I choose?
ACH600S-XY for everyday work in air up to 600 °C on oxidation-tolerant samples; ACH400SV-XY (vacuum) whenever the sample must not oxidize — metals, perovskites, air-sensitive 2D materials (see the simulator above).
