780nm AR-coated fiber optic patch cord

Fiber patch cords (also known as fiber connectors) are optical cables with connector plugs installed on both ends to achieve active connection of optical paths. Both ends of our fiber patch cords are high-quality, narrow-pin ceramic FC/AFC connectors. The fiber end faces of this fiber patch cord are coated with anti-reflection coating. Produced by our equipment, each patch cord is individually tested at the test wavelength listed on the specification label to ensure the extinction ratio and low back reflection (return loss) when connecting fibers to fibers.

Anti-Resonant Hollow Core Fibers

Optical signal in hollow core anti-resonant fibers propagates in an air core surrounded by single ring of anti-resonant tube elements. Guidance is based on an anti-resonance from the thin glass membranes constituted by the non-touching tubes surrounding the hollow core. The extremely low overlap of guided power with the surrounding silica, less than 2x10-5, added to the mode effective area, confers to these fibers design record material non-linearity.

635nm FC/PC Fixed Fiber Collimator with NA 0.37 and Focal Length of 10.1mm.

Idealphotonics' fiber collimators are pre-aligned to collimate light from FC/APC connector fibers and have diffraction-limited performance. These fiber collimators have no moving parts, are compact, and can be easily integrated into existing devices. Because aspheric lenses produce chromatic aberration, the effective focal length (EFL) is wavelength-dependent. The design wavelength is the wavelength corresponding to the ideal beam divergence angle. Some collimators at the design wavelength have different collimated beam diameters. When connected to specific single-mode fiber jumpers, they can collimate light at the design wavelength. In addition, the aspheric lenses are anti-reflection coated on both sides to minimize surface reflections (see the AR Coating Curves tab). For some applications, the collimators can also be used for other wavelengths within the AR coating wavelength range. Please refer to the theoretical divergence angle curves of each collimator to determine whether it is suitable for your application. These collimators have a stable operating range from -40°C to 93°C. Please note that these collimators cannot be used in a vacuum. If you need a custom alignment wavelength, operating temperature, or vacuum compatibility, please contact us for customization

Single-mode wedge lens fiber (including Angle 75 degrees R Angle 5um mirror ridge chamfer 25um)

Lens fiber, also known as fiber lens or fiber microlens, is a type of product that is processed into a fiber end face with lens function. The main functions of lens fiber are to change the size and shape of the fiber mode field to improve the system coupling efficiency, change the optical transmission path, reduce refracted light, and change the tip shape to adapt to imaging and sensing in different environments. It has a wide range of applications in many fields. Idealphotonics can customize multiple types of optical fibers according to the different requirements of lens fibers in different fields and customize the surface metallization of optical fibers according to customer requirements. Compared with products on the market, Idealphotonics lens fiber has the advantages of smaller cone angle error and smaller eccentricity. At the same time, all lens fibers can be metallized + tube shell gold tin packaging according to customer requirements, as follows
