New Fluorescence Probe Virtually Eliminates Back Reflection From Excitation Radiation

(Nanowerk News) Ocean Optics, a leader in miniature photonics, has added the novel QF600-8-VIS/NIR Fiber Optic Fluorescence Probe to its line of spectroscopy and optical sensing technologies.
The new probe is designed to eliminate the back reflection from excitation radiation, resulting in a greater fluorescence signal than can be achieved using more traditional fluorescence probe design parameters. Depending on experiment conditions, order-of-magnitude fluorescence signal improvement is possible.
The QF600-8-VIS/NIR uses one flat fiber for detection and seven angled fibers that direct excitation energy to the region in front of the detection fiber. Depending on the excitation wavelength, an adjustable window can facilitate choosing the depth of overlap.
Custom options for the QF600-8-VIS/NIR are available at additional cost, including different fiber wavelength range versions, various connectors and jacketing options, and custom lengths (two meters is standard). Solarization-resistant fiber is also available.
