How much magnification is best for fiber optic gratings
Q: What is the best magnification power for a fiber optic scope? A: Usually, 100x to 400x is considered optimal for viewing fiber end faces, with lower power scopes, 100 – 200x, suitable for multimode connectors, and 200 – 400x for more critical inspection needs of single mode. An optical fiber grating is a small segment within an optical fiber altered to act as a selective filter for light. This treated area functions like a specialized mirror, reflecting a specific wavelength of light while allowing all other wavelengths to pass through. Single mode fiber is often used for sensing when extreme sensitivity to the measurand is required. This is because this type offiber permits the construction of guided wave interferometers directly from the fiber itself. We demonstrate fast writing of strong fiber Bragg grating (FBG) without hydrogen loading using 343 nm femtosecond pulses of only 7 μ μ J energy at 60 kHz repetition rates and a two-mask interferometer.
