Square-Core Energy-Homogenizing Fiber IR100×100170320
Square Core Homogeneous Energy Optical Fiber is specially designed for flat energy distribution. Unlike ordinary single-mode fiber (SMF), which concentrates energy centrally, square/approximately square cores distribute energy across the full core. Square or rectangular power-delivery cores match semiconductor-laser output modes and improve coupling. Fiber combiner assemblies combine N diode modules while preserving beam quality, with brightness ratios approaching 1. Modes fill square cores uniformly regardless of input position. Conventional round fibers may produce uneven superposition/loss; square cross-sections stack tightly and deliver efficiently, increasing power density/transmission efficiency for stable uniform combining. They also address mode matching: semiconductor outputs are generally Gaussian, described as mismatched to round-fiber output. Square cores capture/transmit this energy more effectively for improved conversion and beam quality. Spot homogenization ensures consistent processing. Where round fibers produce nonuniform spots, square structures distribute energy evenly and deliver stable uniform output. Uses include lasers, welding/cutting/marking, astronomy, night surveillance, and laser biological-evidence detectors. Manufacture is harder and costlier, so current applications/choices remain limited, though development may expand use. Distinctive transmission/energy characteristics are important wherever uniform illumination is needed. Overall, square-core fibers serve diverse fields and provide practical benefits.

Fiber Processing Tools C108 Optical Fibers Jcoptix
Compatible Fiber Types: Single-Core Silica Fiber Compatible Fiber Specifications: Ø0.25 mm/Ø0.9 mm/Pigtail Clamp Type: Multifunction Fixture
JCOPTIX offers the full COMWAY range of high-quality fiber-processing tools, combining high precision, efficiency, long life, and versatility. Precise blade-gap calibration for thermal stripping and stripping tools avoids core damage and removes coatings evenly without residue. Convenient operation and maintenance support fiber splicing in communication engineering, data centers, FTTH, emergency field repair, research, and teaching, making them standard tools for professional splicing. Fiber cleavers. Models: CC-03, C108, C109, C109M. High-precision cleaving. Durable, long-lived construction. Easy operation and maintenance. JCOPTIX supplies original COMWAY cleavers with precision mechanics and hard-alloy blades for stable cleave angles. Blade life reaches up to 48000 cleaves, combining efficiency, precision, and durability. Place fibers in the correct groove strictly according to instructions. If fibers do not cleave or edges are rounded, adjust the blade position with the screw and cleave again. If quality deteriorates noticeably, generally after 1000-1500 fibers, loosen the blade-clamping screw and adjust the blade position according to instructions. Thermal fiber strippers. Models: CS-06, CS-09. Thermal stripping without fiber damage. Four temperature settings and dual modes. Portable, long battery life. Easy operation and maintenance. Original COMWAY strippers use constant-temperature thermal stripping instead of conventional cold stripping to avoid core scratches and coating residue. Four temperatures, dual modes, a high-capacity lithium-ion battery, and Type-C fast charging suit bundled fibers, ribbon cables, pigtails, bare fibers, invisible fibers, and other fiber coatings. Replace both blades together according to instructions. Fiber stripping pliers. Model: CS-02-B. Three-hole design. Safety lock. Easy, quick operation. Original COMWAY pliers include 3 standard stripping openings for layered removal of 2.0-3.0 mm outer jackets, 900 μm buffers, and 250 μm coatings in one operation. Micrometer-calibrated hard-alloy blades prevent core scratches and breaks; ergonomic nonslip handles combine efficiency and durability. Users may adjust aperture size as needed, but manual adjustment cannot be restored to factory settings with one action. Open the safety lock before use.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
