Fiber for Fluorescence Temperature Measurement SMA-DUVYG-01
Fluorescence temperature-sensing fibers use fluorescent materials, such as rare-earth-doped glass, to monitor temperature. Excitation produces specific-wavelength fluorescence whose intensity/lifetime changes with temperature. Precise measurement infers temperature at the fiber location. Beyond directional surface measurement, probes enter solids, liquids, or equipment to reach selected regions. Compared with other methods, accuracy is unaffected by surface emissivity, with high sensitivity and accuracy at low-to-medium temperatures. Probes have three sections: ST connector, fiber cable, and terminal sensing end. The ST connector joins the optoelectronic module. The cable contains silica fiber, coating/cladding, and an outer Teflon sheath. The terminal rare-earth material generates temperature-bearing signals. The whole fiber withstands 200℃ and has 3mm outside diameter, 13.2cm long-term bend radius, and 4.4cm short-term bend radius. Guangyan Technology designs provide flexibility and mechanical strength, with requirements changeable to meet needs. Low power loss, rapid heat dissipation, high conversion efficiency, and free extension are among the advantages. 1. Probe: fluorescent material at one end, placed in the measurement environment. 2. Excitation source: generally a laser exciting probe fluorescence. 3. Detection system: receives temperature-dependent fluorescence changes and converts them into readings. Applications include industrial process control, medical monitoring such as body temperature, and research such as materials studies. Advances in materials and optoelectronics will further improve performance and broaden applications.

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.
