DTF-MIR 2300-4000

The DTF-MIR 2300-4000 from Orientalfiber is a high-performance hollow-core optical fiber optimized for mid-infrared wavelength transmission. Unlike traditional solid-core fibers, this advanced air-core fiber guides light through an air-filled structure, effectively reducing material absorption, nonlinear effects, and thermal limitations in the mid-infrared spectrum. With a wide transmission bandwidth of 2300–4000 nm, low dispersion, and high higher-order-mode suppression, the fiber ensures precise beam quality and stable optical performance for demanding industrial and scientific environments. 

Widely applied in mid-infrared laser delivery, gas analysis, spectroscopy systems, defense sensing equipment, and laboratory research, the DTF-MIR 2300-4000 demonstrates excellent reliability and long-distance transmission capability. Orientalfiber, as an experienced hollow-core fiber manufacturer and supplier in China, offers factory-direct procurement, strict quality control, and professional optical fiber solutions for global customers.

Hollow-core fibers—such as the Orientalfiber factory DTF-MIR 2300-4000—guide light waves through an air-filled core rather than a solid glass core. This design minimizes the interaction between light and the fiber material, thereby achieving lower transmission losses and reducing nonlinear effects. Currently, this type of fiber is finding increasingly widespread application in the mid-infrared spectrum, a domain where standard silica fibers are unable to perform effectively.
