방사선 경화 광섬유 플레이트(rhFOP)
방사선 경화 광섬유 플레이트(rhFOP)
픽업 사용 가능 여부를 로드할 수 없습니다.
- 방사선 손상으로부터 센서를 보호하세요
- Xray 브라우닝에 대한 저항성(장기간 사용 후 갈색으로 변함)
- 형광체에 의해 생성된 산란광을 흡수합니다.
rhFOP은 Xray 에너지를 흡수할 수 있는 재료로 만들어졌습니다. 형광체(신틸레이터)로부터 과도한 Xray 누출로부터 센서를 보호합니다. 이는 센서의 수명을 향상시키고 시스템의 SNR도 증가시킵니다.
*rhFOP는 기본적으로 세륨이 첨가된 것입니다.

Specifications
-
Single Fiber diameter
Smaller fiber size means higher resolution. (2.5um = 218lp/mm , 6um = 114um )
- 2.5um
- 3um
- 4um
- 6um
-
Maximum Size (Diagonal)
Production cost will increase sharply once diagonal surpass 130mm. If you need a bigger size, please contact us.
- Max. size Φ200mm
-
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.
- Minimum 0.2mm
-
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 EMA (Left)
- Without EMA (Right)
-
Numerical Aperture
Numerical Aperture are decided by the material using to produce the FOP.
- NA = 1.0

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

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.
-
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.
