1.5x – 3x Fiber Optic Taper (sFOT)
- 1.5x – 3x Image Magnification (or Concentration)
- High Sensitivity (Suitable for Low-light condition)
- Compact Structure (Less bulky than Lens System)
- Low Distortion (No Spherical, Coma aberration)
- Easy Configuration (Direct coupling to CCD, all defects are static and removable by alogrithm)
Fiber optic taper is an important component in the scientific camera,xray imaging,fluoroscopy.
The large end of each fiber represents a segment pointing at a specifific direction and guiding the incoming light to the detector, which can receive multiple modes, in a direction normal to its active area. You can achieve the same design with lower cost and complexity.
The specification below are refer to the production possibility with a certain type of material.
You can customize the sFOT with specification mentioned below.
| wdt_ID | Parameter | Value | Remarks |
|---|---|---|---|
| 1 | Fiber Diameter (Small End) | >= 2um | Smaller than 2um is also possible, but quite experimental with us. (meaning costly and easy to fail) |
| 2 | Magnification Ratio | 2x - 3x | Key Parameter of Fiber Optic Taper, you need to specify this when ordering |
| 3 | Fiber Diameter (Large End) | Small End x Magnification Ratio | The fiber size on large end |
| 4 | Resolution | maximum 228lp/mm | Tesing with USAF1951 (3um fiber size on small end) |
| 5 | Numerical Aperture (N.A) | approx 1.0 | The numerical aperture here is referred to N.A on small ema |
| 6 | EMA Absorber | Interstitial Type or Without | The insert type of special fiber to absorb stray light |
| 7 | Surface Geometric | Circle to Circle, Rectangle to Rectangle |
Single Photon Counting Detector:
 |
| Detectors with thin continuous scintillators and (charge coupled devices) CCDs have been used for animal SPECT imaging for their high intrinsic resolution. Thicker scintillators augment detection efficiency but also increase the light spread and difficulty in identification of gamma events.
Fiber optic taper was chosen to simplify the optical propagation model. |
Lenless Fluorescent Microscopy:
 |
| lens-based optical microscopes have been extensively used for imaging of biological specimens and associated micro-fluidic platforms. With recent advances in fluorescent labeling technologies and imaging components, various discoveries have been made in biological sciences through the use of lens-based microscopes. However, typical imaging field-of-view of such a lens-based optical microscope is not yet compatible with the scale of the micro-fluidic devices that are especially used for high-throughput screening applications.
In addition to this, their relative complexity also makes conventional lens- based microscopes rather bulky and expensive, limiting their use to relatively advanced laboratory settings. Here demonstrate a lensless on-chip microscopy platform that can image fluorescent objects over ~60 mm2 field-of-view with <4 µm spatial resolution without the use of any lenses, mechanical scanning or thin-film interference filters. |
sFOT Glossary
| Terms | Definition | Reference |
|---|---|---|
| Fiber Diameter (Large End) | Usually refer to the Fiber Size on Large End of FOT. | - |
| Magnification Ratio | The magnification scale from input to output | - |
| Numerical Aperture | The acceptance angle (a cone) of the component | - |
| Resolution | Decided by the fiber size. Smaller fiber size means a higher resolution the component can convey. | - |
| Taper Height | Usually Taper height is around the large end diameter. But there are a few technique could reduce the height. (at a cost of higher distortion and higher price) | - |
| EMA Absorber | In addition to the mono fiber elements, a second fiber is used in the construction of the multi fiber. Extra-mural absorption (EMA)fibers are special black absorbing fibers, inserted between (or in place of) mono fibers, which will absorb stray (scat-tered) light in the fiber optic material. |
