Fiber Optic Plate can act as a relay component for conveying image from one side to another side. Due to no requirement on focus distance, it can be used in many compact optical design.

And the shape could be very flexible, Round, Square, Concave, Convex or customized.


  • A “Zero-Thickness “Optical Window for image transfer.
  • Numerical aperture ranging from 0.09 – 1.0. Useful for angular light control.
  • Reduce color shift and Non-uniform brightness. Enhance Contrast.

Following explanation to the terms that you should know about Fiber Optic Plates.

1.Fiber Diameter (Pitch)

Diameter of a fiber strand / Distance between fiber centering

2.Numerical Aperture

Capability of light gathering of fiber optic components.


The measure of how closely lines can be resolved in one milimeter


Extra Mural Absorption(EMA) are small black fibers that inserted between 2 fiber strands. Which will absorb stray light between fibers.


The transmitting part of the fiber optic wave guide. (Core usually has higher refraction index than cladding)


The cover outside core, cladding has a lower index of refraction than core.

7.Packing Fraction

Ratio of Core area to Total area, this will shows the light transmission efficiency of the component.


Comparison between Output light intensity and Input Light Intensity

10.Optical Crosstalk

The light escape from one fiber strand and get into another fiber.


Blemishes are the area where transmission is reduced. Blemish is caused by contaminants along in the fibers.


Chicken wire appear likes a black line on the components. The result of chicken wire is due to mal-control of temperature or pressure during the procedure.

13.Coefficient Thermal Expansion

CTE defined as the changing of dimension when the fiber components exposed to changing temperature environment

14.Shear Distortion

Shear distortion is cause by the misalignment of fiber during fusion process.

15.Gross Distortion

Gross Distortion is cause by in-proper Temperature/Pressure and Material input procedure.
