The BAC201 is a fiber optic Raman probe designed to analyze samples at hard-to-reach places, such as inside small cavities, tissues, and miniature reactors. The probe end is constructed with a single 200 μm core laser fiber surrounded by nine 200 μm core return fibers, all encased in a 3.0 mm OD stainless steel needle tube. The tip is sealed with a fused silica ball lens, which allows for high throughput and easy cleaning. The optical elements inside the needle are permanently fixed in alignment, with no possibility of movement due to impact or vibrations. At the spectrometer end, the collection fibers are formed into a linear array in a SMA905 terminal, and the laser fiber is terminated in FC/PC.
The probe can be used for immersion or direct contact measurements. Avoid strong acids, bases, or other chemicals that might attack fused silica or stainless steel.
