Product information

FB-240 / Optical fiber curl measuring instrument

It measures the bending of the optical fiber.

Computer、Detecting unit FB-240

This system is for measuring optical fiber curl offline.
FB-240 functions by running software on the PC which is connected with the Detecting unit via RS-232C.

Features
This equipment emits two parallel laser beams to glass fiber,and measures the distance between the two laserbeams on the CCD line sensor reflected by glass fiber.
The curl of fiber is represented by curvature k[1/m] and radius of the curve r[m].
The relation between curvature k[1/m] and radius of the curev r[m] is k=1/
Curvature k[1/m] of fiber is l = 1/2L * (ds/dz - 1)
(k: Curvature[1/m],
dz: Standard distance between the two laser beams[mm],
ds: Measured distance between the two laser beams on the CCD line sensor reflected by the fiber[mm],
L: Distance between the fiber and the CCD line sensor[m])
