Fiber Optic Block
Fiber Optic Plate
  • 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.
  • Support Image Resolution up to 120lp/mm
  • Blocking Xray from damaging CMOS/CCD (Xray Shielding Type FOP)

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 aspherical can be made. Further simplify the design.

Applications :  Dental Xray / Scientific Camera / Fingerprint Sensing / Angular Filter

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.

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.

What’s the relationship between fiber size and resolution?

Smaller fiber size lead to a better resolution,  there’s a rough way to estimate the resolution.

Resolution = 500 / Fiber Diameter

However, the real resolution could be larger than this.

For example, 6um size fiber will have resolution around 100lp/mm

How thin can i make with the fiber optic plate?

With the dimension increase, minimum thickness will often go up.

For a small format Fiber Optic Plate (Diagonal < 10mm), the thickness could go down to 0.5mm.

Medium format (50mm > Diagonal > 20mm) requires a minimum thickness of 1mm.

Large format ( Diagonal > 50mm) requires a minimum thickness around 1mm – 5mm.

How to increase transmission ratio?

For a certain spectrum, following factors will have impact on transmission.=

  • Material
  • Thickness – ~ (Transmission +)
  • Core-Clad ratio + ~ ( Transmission +)
  • EMA Setup ~ (Transmission -)

Factors above are sorted by importance.  (1)> (2) > (3) > (4)

How to improve imaging performance?

Resolution is merely decided by Fiber Size. Smaller fiber will lead to a better resolution

MTF (Contrast) is decided by Thickness,Fiber Size,EMA setup.

Thinner Thickness + Smaller Fiber Size + EMA (Intersitial) will lead to a better performance.

Do i need to pay extra dollar for making sample? Is there any minimum order quantity?

Usually, additional cost is not required when making samples. Unless in below cases.

  1. We don’t have that material type.
  2. The sample dimension is too large.
  3. Samples require a very high spec.

And we don’t set minimum order quantity for Fiber Optic Plate products. You may start from 1 pc.
