Fiber Optic Collimators
Fused Fiber and air gap Collimators available
Singlemode, multimode or Polarization maintaining fibers
Custom fiber optic assemblies
LightPath Fusion™ Collimators and fiber optic assemblies utilize proprietary fiber fusion technology that allows collimators to be used at higher powers for pairing, targeting, or pigtailing applications. The lens is laser fused directly to the optical fiber, eliminating any interface causing unwanted signal distortion, photo-degradation, and space shifting issues with temperature and service life. Recognized by commercial and scientific industry leaders for offering unmatched stability against other technologies in various environmental conditions, as well as perfectly suited for extremely small packages.
With LightPath Laser Fusion and sophisticated assembly processes, the fiber optic assembly puts an end to any glass-to-air interface and simplifies the component layout. This eliminates surface effects and damages caused by 405nm laser irradiation that is generally experienced by unprotected fibers operating just a few milliwatts of continuous power transmission. In addition, the design stabilizes movement toward the target and delivers high laser-quality, essential for smooth signal transmission. Therefore, the time and speed of the photons are very well reserved, and it is possible to check the security of the transmitted key.
