HONSUN Fiber Image Expander for High-Efficiency Coupling
HONSUN is highlighting its Fiber Image Expander for optical assemblies that need image enlargement or reduction without a bulky lens train. Designed for CCD/CMOS image coupling, the component combines high resolution, efficient light transmission, strong contrast, and a compact form.
At a glance: Millions of optical fibers transfer pixel information by total internal reflection. A change in fiber diameter enlarges or reduces the image while retaining its original arrangement. HONSUN offers custom magnification and round or square formats.
How the Fiber Optic Expander Transfers an Image
An image presented at one face is divided into corresponding picture elements by millions of individual fibers. Each element travels through the fiber structure by total internal reflection and reaches the opposite face in its original position.
The fibers change diameter along the component. This produces image magnification or reduction without disturbing the pixel arrangement. Rather than simply moving an image from one plane to another, the Fiber Image Expander also adapts its dimensions to the next optical element.
Image Magnification Optics with Controlled Geometry
Useful coupling depends on more than the magnification ratio. Input and output dimensions, resolution, distortion, transmission, and mechanical fit must be reviewed together. A properly specified expander helps engineers use the available image area while keeping the assembly compact.
High-Resolution Image Transfer: Key Specifications
HONSUN’s published product data provides a practical starting point for design review:
Parameter | Published specification |
Fiber size | 6 μm |
Numerical aperture | > 0.65 |
Collimated light transmission | ≥ 65% |
Lambertian light transmission | ≥ 58% |
On-axis resolution | ≥ 100 lp/mm |
Gross distortion | ≤ 2% within the useful area |
Pincushion/barrel distortion | ≤ 2% within the useful area |
Available forms | Round or square |
Magnification | Customized |
These figures describe the listed Fiber Image Expander. Final requirements should be confirmed against the intended coupling arrangement and acceptance criteria.
Fiber Optic Taper for CCD/CMOS Coupling
In a CCD/CMOS coupling set, the expander provides a direct optical interface between image planes. Efficient coupling can reduce the space required for the optical assembly, while the fiber structure supports high-resolution transfer and contrast.
For radiographic imaging, the coupling set can be combined with a scintillator. HONSUN also supports array combinations for larger-area imaging layouts. Design work should account for alignment, useful area, distortion limits, and the required magnification—not magnification alone.

Custom Fiber Image Expander Development at HONSUN
A productive technical review begins with the input image size, required output size, resolution target, illumination conditions, distortion allowance, and available mechanical envelope. Round and square formats give engineers flexibility during layout, while custom magnification supports application-specific matching.
HONSUN can then review the optical and mechanical requirements before confirming the production specification. This keeps purchasing, engineering, and quality teams working from the same acceptance baseline.
A Compact Route from Image Input to Coupled Output
The Fiber Image Expander combines image transfer and dimensional matching in one compact component. For designers balancing resolution, transmission, coupling efficiency, and space, it offers a direct alternative to a mor+
e elaborate optical arrangement.
