Optical Heating & Cryo Stage

Overview Specification Applications Related Products Order Now!

The temperature control stage is scientific research equipment used in professional fields such as materials, geology, food, and medicine. It can be combined with optical microscopes, Raman microscopes, fluorescence microscopes, and other instruments to achieve rapid sample heating or Cooling, while observing the structural and morphological changes of the sample during the process, it helps to understand the physical and chemical properties of the sample.
Temperature Control System

Features ● Temperature control accuracy: ±0.1 ℃ ● Supports transmissive/reflective mode ● Compact structure, suitable for various variable temperature tests ● Wide temperature range: -190 to 600℃ / Room Temperature to 1200 ● Gas-tight chamber design, can flow protective gas ● Upgradeable vacuum chamber design, 10^-5mbar ● The optical windows can be replaced for different materials ● Can be replaced with different types of optical interfaces ● PC software control supports modification or customization
	Gas-tight Optical temperature control stage Protective gas can be passed through	Vacuum Optical temperature control stage Mechanical pumps up to 10^-3mbar Molecular pump up to 10^-5mbar

Light Transmission Mode

Reflection Mode	Stage	Transmission Mode (2mm Stage hole)


Light-transmitting Window Material 1 ) Sample stage material: silver (medium and low temperature), ceramic (high temperature) 2 ) Sample stage size: 23x23mm (can be customized) 3 ) Light transmission hole: 2mm (can be customized) 4 ) Window material: optical glass, sapphire, calcium fluoride etc. 5 ) Window size: φ 25mm (can be customized)		Sample / Window Defrosting Sample Defrosting Method a. Flow protective gas, b. Vacuum Window Defrosting Nitrogen purges the window glass.

Customized Optical Interface

Liquid Nitrogen Consumption 1 ) The maximum liquid nitrogen consumption is 1L/h, maintained at -190 ℃ ; 2 ) Normal use 0.5L/h, high and low temperature changes.

Water Cooling System
Water circulating system (temperature control)	The water circulation system is needed for Ultra-low or High-temperature environments. It attaches to the Temperature stage chamber ● For low temperatures application down to -190 degrees it will prevent water condensation to the stage and chamber ● For high-Temperature application it will cool the chamber wall to room temperature for safety
