Abstract
We have developed three instruments for accurate measurement of optica l fiber cladding diameter: a contact micrometer, a scanning confocal m icroscope, and a white-light interference microscope. Each instrument has an estimated uncertainty (3 standard deviations) of 50 nm or less, but the confocal microscope may display a 20 nm systematic error as w ell. The micrometer is used to generate Standard Reference Materials t hat are commercially available.
