Custom Component
At Castor Optics, we develop and manufacture a wide variety of fiber optics components. Our state-of-the-art production facilities and agile team are capable of delivering both small-batch prototypes and high-volume OEM components. Our history of working with industrial R&D groups, research institutes, and academic and national laboratories makes our development abilities versatile.
We can produce components based on combinations of different fiber optics types, for different geometries and various illumination or detection schemes.
See below a few examples of products developed following custom requests.
Our Capabilities
- Specialized splitters and Wavelength-division Multiplexers (WDM)
- Custom fiber design
- Custom packaging such as in-ferrule or in-cannula structures, OEM-compatible, and high-power
- Improved performance features such as low auto-fluorescence and high return loss connectors
- Custom geometries such as half couplers, 3+ fused fiber bundles, mode converters, and tapers
→ For custom product inquiries, please provide the following information to help us better understand your needs:
Optical specifications: Operational central wavelength and range, fiber optic core size and numerical aperture (NA), fiber type (single-mode or multimode), and maximum power level.
Sensing modality: Specify the application, such as fluorescence, confocal, LiDAR, OCT, or spectroscopy.
Mechanical and environmental considerations: Any relevant constraints or requirements for integration and environmental conditions.
Product lines
FB1300B5 : Fused fiber bundle, 1300nm, 5 fibers
(4+1)x1 configuration
Central fiber diameter: 8/125 µm
External fibers diameter : 200/220 µm
Insertion Loss: <0.5 dB
This fiber bundle is composed of 5 optical fibers merged into one compact structure. The central fiber is single-mode with an external diameter of 125 µm and is surrounded by 4 multimode fibers of 220 µm external diameter.
Other fiber types and bundle configurations are available.
WD1300L
This wavelength combiner is designed to combine a 1310 nm channel with a 400-900 nm channel.
Insertion Loss (at 1300nm) (dB): <0.5 dB
Isolation (at 1310nm): <22 dB
This product is used in our interferometer modules.
Other wavelengths are available upon demand.
Low AF connectors
These connectors are designed to reduce auto-fluorescence background in connectors.
A 3 dB reduction was measured when used with a multimode 200/220 µm fiber.
Available for all our products.
