Laser diffraction sensors for fibre optic diameter measurement
CERSA-MCI, France, specialises in the design and development of optical metrology such as laser diffraction sensor (LDS series) for fine wire diameter measurement, laser projection sensor (LPS series) mainly for the cable industry, as well as laser interferometric sensors (LIS series) suitable for the fibre optic industry. Thanks to their sensitivity and repeatability, CERSA equipment provides customers with reliable and accurate quality control tools and the capability to certify the whole production within close specifications.
The company offers a range of instruments specially designed for fine wires and cables. This range comprises laser diffraction or projection instruments, on drawing machines or in laboratory, suitable for diameter, ovality measurement and fault detection (olives, lumps, neck…) of ultra-fine wires and cables:
- Model LDSN suitable for Ø from 5 to 2,000µm ±3% of the diameter;
- Model LPSN suitable for Ø from 0.5 to 25mm ±5µm;
- Model LPSNH3 (3 axes) 10KHz suitable for Ø from 0.5 to 25mm ±20µm.
The company has recently released a new version of its LDSN series, designed to control cables and wires ranging from 5 to 2,000µm. For the optical fibre industry, the new LIS series features outstanding performances, multi-parameter measurement and defect detection. This range of laser interferometric measuring instruments ensures optical fibre qualification and certification on drawing towers. These instruments are suitable for application to telecommunication fibres, special fibres, GGP, single coating layer. The LIS range of instruments comprises:
- Laser interferometric sensor, model LIS-G that provides high-speed absolute diameter measurement of glass and fault detection (inclusions, airlines);
- Laser interferometric sensor, model LIS-C, that offers an absolute diameter and eccentricity measurement of coating and fault detection (olives, inclusions, bubbles, delaminations, lumps, necks…);
- Fibre eccentricity measurement, model FEM, and fibre eccentricity display, model FED, that provide an electronic or visual eccentricity control of coating.
Furthermore, CERSA recently developed in co-operation with a key Asian fibre manufacturer, the NCTM system designed for optically fibre drawing force measurement. This new system get performance never reached until today, according to the company. In addition, the company recently patented a method to measure in-line the surface quality of wires, as well as to detect blisters in enamelled wires. All these measurement instruments come with PC software for parameter setting, data recording, software upgrade. They can be connected in network with software for production and quality management.
