The UC INSTRUMENTS GM8037 portable high resolution fiber grating sensor instrument is a high power with high accuracy and wide dynamic range for fiber Bragg grating (FBG) sensors, and compact PC-based interrogation system, and is also a high accurate optical spectral analysis system. It includes an external device, PC-based application software and optional high performance laptop. With a build-in tunable laser source and two channel photo detectors (no additional light source is required), the system can perform high accurate measurements in temperature, strain, and pressure in conjunction with FBG sensors/sensor arrays. Meanwhile it is a high accurate optical spectrum analyzer. The system provides users explicit understanding of how the spectral shape of FBG sensors rapidly respond to varying temperature, stain, pressure in the detection environment - rather than only reporting shifts of the detecting central wavelengths. This instrument is used in both the initial development of high-volume custom sensing systems and also long term field measurement applications. The two detector channels allow simultaneous interrogation of multiple sensors (up to 20 sensors per channel) in one channel and both channel analysis. Each optical channel can be used to interrogate fiber gratings in either transmission or reflection. A wide variety of fiber optic sensors/sensor arrays can be used with the system. All data can be transferred to an external PC via a RS232 or USB communication port. Specifications. Built-in Laser Wavelength Range: 1525.00 to 1566.00 nm. Built-in Laser Output Power: >= 20 mW.
