Lower Numerical Aperture Fiber Optic Plate(lnaFOP)

  • Low Numerical Aperture (0.1 – 0.4)
  • Fiber Diameter from 6um

Lower Numerical Aperture Fiber Optic Plate (lnaFOP) can be used as angular filter, it can block the light outside the acceptance angle. (Extinction ratio up to 99.5%)

The specification below is referred to the production possibility with a certain type of material.
You can customize the lnaFOP with specification mentioned below.

wdt_ID Attributes Values Notes
1 Single Fiber diameter 6um / 10um Smaller fiber size means higher resolution. ( 6um = 114um )
5 Maximum Size (Diagonal) Φ100mm 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 0.1 - 0.4 Numerical Aperture are decided by the material using to produce the FOP
39 Wavelength 350 - 800nm -
40 Transmission 50 - 65% Tested a sFOP of 5mm thickness, with EMA absorber, collimated light
