The Laser to Fiber Coupler with Receptacle (Non-Contact Style) is an advanced optical coupling solution designed for high-performance applications across a broad spectrum of industries. Unlike traditional contact-style couplers, this non-contact design introduces an air gap between the fiber and the lens, offering enhanced flexibility and adaptability. This configuration allows users to select from a wide range of lens types—including GRIN, achromats, aspheres, fused silica, plano-convex, and biconvex lenses—enabling precise control over focal length and beam characteristics. The adjustable distance between the fiber and lens makes it possible to compensate for changes in source wavelength or to intentionally defocus the laser beam, which is particularly beneficial in high-power laser to multimode fiber applications to prevent arcing.

Engineered for robust performance, this coupler can handle continuous wave (CW) input powers up to 100W, and even higher energies from pulsed laser sources. It is ideally suited for demanding scenarios where input energy exceeds 400mW, multiple wavelengths need to be coupled into a single fiber, or when dealing with beams that have large diameters or significant divergence angles. The non-contact design also delivers superior polarization maintaining capabilities, making it an excellent choice for applications where polarization integrity is critical, such as interferometric sensors, spectroscopy, and fluorescence measurements. The coupler is compatible with a variety of connector receptacle versions, including specialized options for improved repeatability and reduced backreflection. Standard connectors typically achieve backreflection levels of -14dB, while angled connectors can reduce this to as low as -60dB. For applications requiring optimal repeatability and minimal variation in endface geometry, the angled flat (AFC) connector is recommended, featuring a beveled fiber endface with a flat ferrule tip. 

Additionally, for users employing SMA connectors, the use of Zirconia ferrules and sleeves is advised for core diameters of 100 microns or less, ensuring precise alignment and consistent performance. With its wide wavelength compatibility (180–2000nm), high coupling efficiency, and exceptional power handling, the Laser to Fiber Coupler with Receptacle (Non-Contact Style) is a versatile and cost-effective solution for laser shows, medical and pharmaceutical sensing, OEM laser systems, and more. Its innovative design and adaptability make it a preferred choice for professionals seeking reliable, high-performance fiber optic coupling in both research and industrial environments.
