  • Protect Sensor from Radiation Damage
  • Resistance to Xray Browning (Turning brown after long-term use)
  • Absorb scattering light generated by phosphor

rhFOP are made from material that can absorb Xray energy. It will protect the sensor from the excessive Xray leak from phosphor (scintillator). Which will improve lifetime of sensor, and also increase the SNR of the system.
*rhFOP are cerium doped by default

Specification

  • Single Fiber diameter

    Smaller fiber size means higher resolution. ( 6um = 114lp/mm )

    • 6um
    • 8um

  • Maximum Size

    Production cost will increase sharply once diagonal surpass 100mm. If you need a bigger size, please contact us.

    • Max. size: 150mm x 150mm

  • Thickness

    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.

    • 1mm - 10mm

  • EMA Absorber

    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.

    • Interstitial

  • Numerical Aperture

    Numerical Aperture are decided by the material using to produce the FOP.

    • NA = 1.0

  • X-ray Shielding Ability

    Thickness: 1.2mm, X-Ray Power 140KVp.

    • 93%

  • Phosphor Compatible

    • Yes

  • Lead Free

    We have 2 types material for making rhFOP. Lead Free and With Lead. Performance are slightly different.

Applications

Using FOP with Scintillator

CsI(Tl) has a primarily columnar crystal structure as seen in Figure below) and, depending on the conditions, approximately 83% is reflected within the columnar crystal.

For this reason, light is guided into the crystal wall and a certain fraction is guided into the photodiode direction. These are referred to asstructured scintillators. CsI (Tl) scintillator can be deposited on substrates such as glass, which is then flipped and adhered to the photodiode. It can also be deposited directly on the photodiode or deposited on the fiber optic plate. (See Below)

Phosphor Scattering

While light travelling within the phosphor, the light will spread—the amount of diffusion being proportional to the path length required to escape the phosphor. X rays interacting close to the photodetector give rise to a sharper (less blurred) optical signal than those which interact more distantly. The paths of most optical quanta will be shortest if the photodetector is placed on the x-ray entrance side of the phosphor.

Fiber optic plate can and directly coupling to CCD/CMOS and absorb scattering light that may blur the image.  Which will improve the SNR of the system.
