980nm In-line Polarizer PM980 Fiber
Idealphotonics' in-line polarizer is designed to pass a specified polarized light and block other polarized light. Its function is to convert unpolarized light into linearly polarized light to achieve a high extinction rate. It is also used to improve the extinction rate of instruments such as precision measurement systems, fiber optic sensors, and high-speed test instruments. We have specially designed in-line polarizers for ring gyroscope systems, and its components have been tested under full temperature conditions. In addition, the mini size is very suitable for our cost-effective fiber optic gyroscope system.
Product features:High extinction ratio、 Low insertion loss、 High return loss、 Full wavelength selection、 Wide operating bandwidth
Part Number:--
Application area:Communication systems、 Test instruments、 Fiber optic gyroscopes、 Research、 Fiber optic current transformer (FOCT)、 Fiber optic sensors
