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.

Features:

  • 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.
  • Blocking Xray from damaging CMOS/CCD (Xray Shielding Type FOP)

Application:

  • Dental Xray
  • Scientific Camera
  • Fingerprint Sensing
  • Angular Filter

wdt_ID Attributes Values Notes
1 Single Fiber diameter 2.5um / 3um / 4um / 6um Smaller fiber size means higher resolution. (2.5um = 218lp/mm , 6um = 114um )
5 Maximum Size (Diagonal) Φ200mm Production cost will increase sharply once diagonal surpass 130mm. If you need a bigger size,
6 Thickness Minimum 0.2mm With a larger size of FOP, the minimum thickness required will also go up in order to maintain the structure. Usually thickness will go around 1mm - 3mm.
8 EMA Absorber Interstitial / Without EMA are special fibers insert in-between the standard fibers. They are using to absorb stray light between fibers. But at a cost of lowering the overall transmission
9 Numerical Aperture 1.0 Numerical Aperture are decided by the material using to produce the FOP
39 Wavelength 400 - 1350nm sFOP are produced from multi-component glass. Which has the highest transmission in VIS to NIR range. For UV application, other material will be used.
40 Transmission 70% - 78% Tested a sFOP of 5mm thickness, with EMA absorber, collimated light

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.
