IdealPhotonics' fiber optic temperature sensor is a temperature sensing device based on the Bragg wavelength shift principle (sensitivity ~10 pm/℃). Utilizing the temperature-dependent characteristics of the fiber optic grating (FBG) reflection peak (linearity >99.9%), it achieves high-precision (±0.1℃) temperature monitoring in distributed (single-fiber, multi-point) or extreme environments (-200℃~1000℃), suitable for online temperature measurement in complex scenarios such as power grids and spacecraft.The "wavelength-calibrated absolute temperature measurement" utilizes FBG Bragg wavelength shift (sensitivity 10-30 pm/℃) and demodulation technology (resolution ±0.01℃) to achieve electromagnetic interference resistant, long-term stable (annual drift <0.1℃) distributed monitoring (100+ measurement points per fiber), providing an intrinsically safe temperature sensing solution for nuclear power plants and spacecraft thermal control systems.

IdealPhotonics' fiber optic refractive index sensor is an optical device based on the interaction between evanescent fields or fiber gratings (such as long-period gratings, LPGs) and the external medium. By measuring resonant wavelength shift (sensitivity > 100 nm/RIU) or intensity modulation, it achieves liquid/gas refractive index detection within the 1.30-1.45 RIU range (resolution 10⁻⁵ RIU), suitable for biochemical analysis, environmental monitoring, and other fields.The "Microliter Sample High-Sensitivity Refractive Index Probe," through optimized evanescent field coupling structure (sensitivity 500 nm/RIU) or surface plasmon resonance (SPR) enhancement design (resolution 10⁻⁷ RIU), enables real-time online monitoring of trace liquids (detection volume < 1 μL), providing a label-free optical detection solution for early cancer diagnosis and chemical reaction process control.
