Fiber Optic Probes
FiberTech Optica designs and manufactures custom fiber optic probes engineered to meet the unique optical, mechanical, and environmental requirements of advanced spectroscopy, sensing, and analytical instrumentation.
Our capabilities include probes incorporating multiple fiber types, complex fiber arrangements, and integrated optical elements such as lenses, filters, windows, spacers, beam shaping optics, and custom ferrules. By combining optical and mechanical design expertise, FTO delivers complete probe solutions that optimize excitation delivery, collection efficiency, working distance, spot size, and measurement repeatability.
Fiber Optic Reflectance Probes
FiberTech Optica manufactures custom reflectance and backscatter probes optimized for reflection and fluorescence measurements in solids, liquids, and powders.
Configurations typically use 7, 19, 37, or 61 fibers, with center illumination or collection fibers. Different fiber sizes and types can be combined, with isolated center fibers available to minimize cross-talk.

Fiber optic SORS Probes
Raman spectroscopy is traditionally a surface measurement technique. However, methods such as Spatially Offset Raman Spectroscopy (SORS) that collect backscatter data at different distances enable its application for obtaining depth-resolved sample composition. This is useful in some biomedical and pharmaceutical applications where understanding of process time dependence can be important.
Building upon our extensive expertise in design and fabrication of custom fiber optics assemblies, bundles, probes and arrays, FTO has developed in-house capabilities to machine and modify precision optical components such as filter and lenses. This enables us to produce high performance Spatially Offset Raman Spectroscopy (SORS) probes with internal filtering for deep spectroscopy of tissue and powders.
