PFO is a leader in the manufacture of test equipment for characterization of optical fibers. Their products are used by most major fiber manufacturers in North and South America, Europe and Asia, for quality control purposes at different stages including Production of optical fibers in 24/7 manufacturing plants.PFO Fiber Curl Measurement System
The PFO CURL500 system uses industry standard laser scanning techniques as defined in IEC standards to provide fast and accurate characterization of the radius of Curl for all types of optical fiber.
The CURL500 measures the curl on 10mm of free fiber, using a technique called “Dual Beam Differential Laser Triangulation”.
The major benefit of this dual beam method is that the beams are fixed in relation to each other; one acts as the reference for the other and as such the system becomes insensitive to any mechanical influences relating to the rotational and fiber holding mechanism, making it far more repeatable and accurate than the alternative microscope image based measurements that need a mechanical reference for the measurement point. The latest optics, electronics, mechanics and software designs have produced an instrument that is significantly faster than it's predecessor.
