The fiber optic tapers provide a method of minify or magnify an image with minimum distortion in image transfer applications.
All tapers are fabricated to customer specific requirements and can be machined into configurations from round to round, square to square, round to square or rectangular.

Features:

  • Magnification (Minification) ratio up to 4:1
  • Resolution up to 231lp/mm (Small end)
  • No focusing distance is required, Enable a higher coupling efficiency.
  • Expand photosensitive area of CMOS/CCD
  • Compact Design, easier to integrate.

Application:

  • Radiography
  • Fluorescence
  • Imaging
  • Light Field Camera
FOT CUSTOMIZATION FORM

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

1.Fiber Diameter (Pitch)

Diameter of a fiber strand / Distance between fiber centering

2.Numerical Aperture

Capability of light gathering of fiber optic components.

3.Resolution

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

4.EMA

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

5.Core

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

6.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.

9.Transmission

Comparison between Output light intensity and Input Light Intensity

10.Optical Crosstalk

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

11.Blemish

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

12.Chickenwire

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.
