NEWARK, Del., Jan. 13, 2012 — The BAC200, introduced by B&W Tek Inc., is a microlensed fiber optic Raman probe that delivers the performance of a larger Raman probe in a small diameter of <4 mm with enhanced optical collection power. Its design provides immersion and direct contact measurements, enabling applications and measurements previously not possible with standard Raman probes. The fused silica tip is housed in a stainless steel needle tube, resulting in a scratch-resistant, easy-to-clean probe. The optical elements are permanently fixed in alignment, with no possibility of movement caused by impact or vibrations. Its small size, flexibility and durability make it suitable for analysis in biological and biomedical applications with small sample sizes. Scientists performing molecular-level spectroscopic analysis can perform in vivo analyses of specimens without creating apertures any larger than 4 mm.
