Abstract

PURPOSE: To obtain a high-resolution image fiber where the transmission loss is small and disturbance of color balance of pictures is small, by setting the normalized frequency in the visible wavelength region of the optical fiber strand to a specific value.
CONSTITUTION: Normalized frequency (v) of the clad type optical fiber strand is indicated by expression I (2a, λ, n1 and n2 in the expression are the diameter of the core part, the wavelength of the light transferred through the core part, the re- fractive index of the core part, and the refractive index of the clad part, respectively). The optical fiber strand of 2.405W3.832 is used to constitute an image fiber. For example, fiber base materials which satisfy expressions II, III and IV are spun to form the optical fiber strand of the core part diameter of approximately 2.3μ and the clad part diameter of approximately 5.2μ; and if this strand is used to constitute the image fiber, normalized frequency (v) in the visible wavelength region of 4,000W5,000Å can be set within the range of 2.55W3.83.
