Product Description

Key Features
Wide Wavelength Range – Supports 400–2500nm from visible to near-infrared, ideal for spectroscopy, laser transmission, and sensing applications.

Large Core Options – Multiple diameters available (50µm, 105µm, 135µm, 200µm, 300µm, 400µm, 600µm, 800µm, 1000µm) for high-power and multimode light delivery.

High Efficiency Coupling – Step-index design with NA 0.22±0.02 ensures excellent light acceptance and stable transmission.

Durable Construction – Low-OH silica core, fluorine-doped cladding, and polyimide coating provide high-temperature resistance (–40°C to +85°C) and reliability in harsh environments.

Versatile Applications – Perfect for high-power laser energy delivery, fiber-coupled spectroscopy, medical laser probes,industrial inspection, and optical sensing.
