Fiber Optic Fluorescence Probes

Many directions in biophysics, molecular and cellular biology have arisen and are developing precisely because of the new measurement methods based on fluorescence.  For biophysicists, fluorescence has become a fast and sensitive method for studying the structure, dynamics, and functions of biological macromolecules-nucleic acids and proteins.

Fluorescent Fiber Optic Probes from FlexiSpec® product line are designed to measure fluorescence of solid, liquid, and powder samples.

  • Thinnest probe tips with diameter 0.5 mm
  • Fiber Optic Multi-Leg or Y– design Reflection Probe
  • Minimal Cross Talk with Metall Coated Fibers
  • Flat & angled (38⁰) tip design
  • Round-to-Round, Round-to-Line, Hexagonal & octagonal Fiber Probe design

Optromix offers a large variety of specially designed Fluorescent Probes, based on Bifurcated or Multi-Channel Furcated Fiber Optic Bundles with” Illuminating” Leg to carry light from a source to a sample – and “Reading” Leg to carry reflected light to a Spectrometer.

Unlike traditional probes, which have “6-around-1” – fiber bundle configuration, our probes have “7 around 1”, and “9 around 1” design. That’s because in such configurations reflected and back-scattered signals are much higher than in traditional ones.

For special applications we provide < 7 + 12 > design: 7 randomized illuminating fibers with 12 randomized reading fibers.

All Illuminating Fibers of our Fluorescent Probes are with metal coating clad, that why cross-talk between the illuminating fibers is blocked, and in the result – Signal/Noise ratio is higher than in similar probes with fiber polymer coatings.

Our Fluorescent Fiber Probes are available with two, three or four fiber legs, and Round-to-Round (R/R) or Round-to-Line (R/L) construction.
