Fiber Optic Sensors by Lake Shore provide temperature measurement and sensing in applications involving materials and physical sciences research, aerospace cryogenic fuel systems and storage, high energy, plasma physics, RF/Microwave, high voltage, superconducting research and equipment, and other applications in challenging operating environments. These measurements are provided over the widest commercially available temperature range- from -200 °C to +250 °C.

These Fiber Optic Sensors provide unmatched convenience and applicability for researchers, aerospace, and industrial users that need to provide accurate temperature measurements in extreme environments. The unique packaging allows for direct sensor placement without interfering with the multiplexing and chaining capabilities of Fiber Bragg Grating based sensors. Lake Shore’s Fiber Optic Sensors are ideal for advanced research, aerospace, and industrial applications due to their cryogenic operating capability and wide measurement range. An all-dielectric package is especially suited for measuring in places with high electrical noise or magnetism, such as plasma and high-energy test labs.
