Fiber for Laser Coupling

Fiber for Laser Coupling

CNI can supply specialty optical fiber for laser coupling. Our products include single-mode fiber, multi-mode fiber, polarization maintaining fiber, liquid light fiber and fiber with pigtailed GRIN lens collimators for all our existing laser modules from visible to near IR transmission.

Fiber for laser coupling
 Single-mode fiber (FC/PC connector)    Multi-mode fiber (SMA905/FC/PC connector)
Single-mode fiber for core diameter of 4-9 um. Available for visible wavelengths from 400 up to 860 nm.   Multi-mode fiber for core diameter of  50 um, 100 um, 200 um, 400 um, 600 um, 800 um, 1000 um. Support more than one propagation mode.
 Polarization maintaining fiber    Liquid light fiber
Polarization maintaining fiber is available for wavelengths from 460 nm to 780 nm.   Liquid light fiber for core diameter of 3 mm, 5 mm, 8 mm, 10 mm.
 Fiber with pigtailed GRIN lens collimators    
Diameter 1.8 mm clear aperture. Coupled to standard 62.5/ 200/ 400um fibers.    
Note: Standard fiber length is one meter, other core diameters and lengths are available on requests.

Accessories for laser coupling    
 Fiber optic collimator
This collimator is designed to connect to the end of FC/PC or SMA905 connector and contains an AR-coated aspherical lens. It is with ultra compact size and excellent performance which is used to collimate the beam out of fiber.

These collimators are designed to connect onto the end of an FC/PC or SMA905 connector and contain an AR-coated spheric lens. The distance between the spheric lens and the tip of the FC-terminated fiber can be adjusted to compensate for focal length changes or to re-collimate the beam at the wavelength and distance of interest.

 Fiber beam combiner
CNI offers fiber beam combiner, combines 4, 3, 2 fiber beam to 1 (single mode or multimode fiber) output.
 It is made features of ultra compact, long lifetime, optional input wavelength and high transmission. Fiber length, type and connector are optional.
Fiber beam combiner

 Fiber line generator

CNI can offer fiber line generator at all existing wavelengths and output power, also the divergence are available in fan angles of 80° to 114°  for customers' applications. These series lasers can be used to display a uniform straight reference line in alignment, machine vision systems, construction and process control.
  • Uniform straight line after fiber
  • No spotlight on both ends of the line
  • Even distribution on vertical direction of the line
