Optical Heating Stage AH200-Mini/AH600S/AH800S
Product Detail
InSitu Pro™ AH200-Mini, AH600S, and AH800S are heating-only optical stages: when your work starts at room temperature and goes up, they are the simplest way there. Three ceilings to choose — 200, 600, or 800 °C — all with ±0.1 °C stability and 150 °C·min⁻¹ heating, from the palm-sized chamberless Mini to the stainless-steel-staged AH800S for serious high-temperature optics.
Key features
- Three ceilings: 200 / 600 / 800 °CPick by your hottest point — and by stage metallurgy: copper (Mini) to 200 °C, silver (AH600S) to 600 °C, stainless steel (AH800S) to 800 °C.
- Fast, stable heatingUp to 150 °C·min⁻¹ with ±0.1 °C stability across all three models; fixed-point holds and programmed ramps on the same host-computer software, with LabVIEW VIs / C# SDK for custom control.
- AH200-Mini: palm-sized and chamberlessJust 40 × 40 × 12 mm and 0.2 kg with a φ20 mm copper stage — drop it anywhere, place the sample, measure.
- Reflection and transmission optics (AH600S / AH800S)Hand-removable JGS2 quartz windows support both light paths; a twist-off top cover makes sample loading and removal quick — full geometry in the table below.
- Nothing to refillResistive heating with a controllable cooling rate on the way down — no cryogens, no compressors; a water-circulation system protects the body during high-temperature work.
- Quote-ready orderingRequest pricing via this page or the Stage Selector; our engineers confirm the configuration for your optics.

High-temperature atmosphere: plan for oxidation
The Mini runs fully open; AH600S and AH800S run in an atmosphere chamber. When operated in air, oxide growth on many metals and alloys becomes significant approaching 600–800 °C, 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 see:
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 illustrates the model response when the oxidant supply is suppressed. Takeaway: oxidation-tolerant samples — oxides, ceramics, many minerals — are at home here; if your sample must come back chemically intact, look at the vacuum-chamber models such as the ACH400SV (vacuum service to 400 °C). Curves are schematic, not a guarantee for a specific unit.

FAQ
Which of the three?
Decide by your hottest point, then by footprint. Everything under 200 °C on small samples: the palm-sized Mini. Up to 600 °C with full reflection/transmission optics: AH600S. Pushing to 800 °C: AH800S, whose stainless-steel stage takes the heat. All three share the same controller platform and 150 °C·min⁻¹ ramping.
What if I need cooling too?
These are heating-only stages — the cooling rate on the way down is controllable, but there is no active refrigeration below ambient. If your protocol needs active cooling or sub-ambient points, step over to the ACH600S/ACH400SV (LN₂, −190 °C, 40 °C·min⁻¹ cooling) or the Peltier family (−25 to 120 °C, cryogen-free).
Will my sample oxidize at 600–800 °C?
If the stages are operated in air, many metals and alloys can oxidize rapidly at these temperatures — the rate depends on composition, surface condition, temperature, atmosphere, and exposure time; the simulator above gives a schematic comparison. Some oxides, ceramics, glasses, and minerals may be more suitable, depending on phase stability, atmosphere compatibility, and exposure time. For oxidation-sensitive samples the vacuum-chamber ACH400SV covers up to 400 °C; above that, confirm the intended operating atmosphere at quotation.
Where does the Mini fit?
Anywhere a full stage will not: its 40 × 40 × 12 mm chamberless body and φ20 mm copper stage make it the quickest way to put controlled heat under any microscope, probe rig, or crowded bench — reflective work up to 200 °C.
