LBTEK offers two types of broad-spectrum gas light source output fibers: near-infrared quartz fibers and deep ultraviolet-resistant fibers. When wavelengths below 300 nm are required, since quartz also exhibits absorption below 300 nm, the quartz fiber needs to undergo ultraviolet aging treatment. Users can select different fibers as output based on their needs.

The LBTEK Large-Core Fibers are specifically designed for various optical testing scenarios, including ultraviolet radiation measurement, transmission and reflection measurement, water quality and gas absorption measurement, and spectral transmission measurement. The fiber probes of LBTEK's Large-Core Fibers are single-channel fiber probes, utilizing high-purity imported quartz fiber cores. The fiber type is multimode fiber, with a numerical aperture of 0.22, an operating wavelength range of 250-1100 nm, and a core diameter of 400 μm. They are encapsulated with GS engineering silicone, and the sleeve encapsulation diameter is 5.0 mm.

LBTEK's Reflective Fiber Optic Probes can be combined with a fiber optic spectrometer for reflectance measurements of solid and powdered samples. The reflective fiber is configured in a Y-type arrangement, with two fibers sharing a common end (7-core probe) for measuring the sample under test. The other two ends form separate measurement branches: the 6-core port connects to the light source for coupling the illumination input, while the 1-core port connects to the spectrometer for coupling the reflected light signal output. LBTEK's Reflective Fiber Optic Probes are compatible with the LBFS-TA1 reflectance measurement bracket.

The LBTEK Immersion Y-Type Quartz Fiber Optic can be combined with a fiber optic spectrometer for measuring the absorbance and transmittance of solutions. The equipped stainless steel probe is particularly suitable for embedding into industrial production liquid flows for real-time sample monitoring. The immersion Y-type quartz fiber adopts a Y-shaped configuration, with two fibers sharing a common end (7-core probe) for measuring the sample under test. The outer diameter of this probe is 6.35 mm, and the optical path length can be customized by users within a range of 1 mm to 10 mm. In the metal middle section of the probe, the fiber bundle is divided into two parts: the 6-core port connects to the light source for coupling input of illumination, while the 1-core port connects to the spectrometer for coupling output of reflected light signals. LBTEK's Immersion Fiber Optic Probe is compatible with the LBFS-TA1 reflection measurement bracket.
