Double-Clad Fiber
Double-clad fibers (DCFs) from Castor Optics serve as the foundation of our double-clad fiber coupler (DCFC) products, developed to meet the needs of various specialized applications, including Optical Coherence Tomography (OCT), confocal microscopy, or LiDAR. Our DCFs are optimized for a wide selection of wavelength range. The inner cladding diameter is tailored to optimize light collection—making it suitable for fluorescence imaging or spectroscopy—or to ensure effective confocal collection.
Information
Overview
Our double-clad fibers are available for different single-mode operating wavelengths and for different inner cladding diameters. Selection will depend upon the target modality.
All fibers are available in bare or connectorized form, such as a pigtail or patch cord. Refer to the table below for all available customization. Other options may be available on request, so please contact our team to find out more.
| Specifications | Available options |
|---|---|
