Properties common to all products in this list

Commodity: Alloys Material: Thermocouple Alloy Form: Foil (Light Tight) Composition: Ni 90/Cr 10 Temper: As Rolled Thickness: 0.3mm Opacity: Light Tight
T1 Thermocouple Alloy Foil Light Tight (Ni90/Cr10) delivers the same thermal stability, oxidation resistance, and thermoelectric precision as standard foil but is manufactured free of pinholes, blocking all external light transmissions. This makes it critical for high-temperature sensing in optically sensitive environments where light intrusion could interfere with measurements. Industries employ it in infrared detector shielding, photothermal experiment setups, and optical furnace environments. Specific applications include light-blocking thermal reference plates, precision thermocouple strips in photonic measurement systems, and heater elements in laser-based instrumentation. In research, it enables controlled thermal conditions in optical spectroscopy, photothermal calibration studies, and high-accuracy thermal conductivity experiments. The combination of thermoelectric reliability and light-tight integrity ensures superior performance in advanced thermal and optical engineering.
