Title:
IMAGE ELEMENT FIBER FOR IMAGE FIBER
Document Type and Number:
Japanese Patent JPS5684338
Kind Code:
A
Abstract:
PURPOSE: To allow an image element fiber to transmit ultraviolet rays as well as infrared rays and visible light and enhance the light converging capacity of the fiber by superposing SiO2-base clad glass contg. a specified amount of B2O5 and F on SiO2-base core glass contg. a specified amount of Al2O3 and P2O5.
CONSTITUTION: An image element fiber for an image fiber is formed by laminating SiO2-base clad glass contg. 0W30wt% B2O3 and 0W10wt% F on SiO2-base core glass contg. 0W10wt% Al2O3 and 0W20wt% P2O5. This optical fiber transmits ultraviolet rays in spite of the SiO2-base glass, and the refractive index difference between the core and clad is made larger to provide high light converging capacity.
