We are promoting laser lamps, galvos, marking heads, green laser pointers etc till the stock is sold out. Pleasee click here.

Our cluster of innovative fiber optic probes and fiber probe couplers designed for in-line analytical analysis in broad spectral range from UV to mid-IR.

Our immersion fiber probes include ATR (attenuated total reflection), transmission, reflection, Raman and fluorescence probes. All are compatible with any FT-MIR, FT-NIR or dispersion spectrometer, process-photometer, IR-LED or QCL spectral sensor to use in-line for PAT applications.

Our fiber probe couplers (FPC) couple any FTIR spectrometer with various fiber optic probes and upgrade it to eliminate sampling and to run reaction monitoring in-line. Our fiber probe couplers provide high coupling efficiency for ATR absorption, transmission or reflection process-spectroscopy in a broad spectral range from UV to mid-infrared to use fiber coupled FTIR spectrometer not only with LN-cooled MCT detectors, but with uncooled detectors as well.

Our probes design is cleanable for many processes where probe optics can be contaminated by media. Industrial probes are compatible with process-interfaces to secure their semi or full automated use in complete process control systems. They can be retracted, cleaned and calibrated during chemical process to enable remote process-control in any liquid, gas or solid mixtures under harsh environmental conditions. Combined with FTIR or UV/Vis spectrophotometers, our fiber probes facilitate qualitative and quantitative product analysis and enable the determination of specific chemical and physical properties.

Combined with FTIR or UV/Vis spectrophotometers, our fiber probes facilitate qualitative and quantitative product analysis and enable the determination of specific chemical and physical properties.

We offer two categories of product portfolio: standard and customized. The standard products consist of preconfigured probes and probe couplers, which can be implemented in the laboratory, pilot plants or in production. The customized products allow users to custom configure fiber probes and couplers based on their unique process requirements.

Raman Fiber Probes

Raman spectroscopy measures the amount of light scattered in-elastically at different frequencies by molecular vibrations. This results in very detailed molecular fingerprints with high chemical specificity. Raman measurements do not require sample preparation and can be applied to aqueous systems with ease. That’s why, Raman has been used extensively for a wide variety of applications, and appears to be the most promising spectroscopic method for in-line analysis of complex systems.

Our product line includes the high sensitivity Raman fiber optic probe to be used with any Raman spectrometer. Available in two options – multi-wavelength excitation (630-785 nm) and single-wavelength excitation (532 and 785 nm), these fiber probes have a bifurcated design, connecting the probe to both a laser and a spectrometer. Our Raman probe allows to analyze spectra in fingerprint (FP, 800-1800 cm-1) and high wavenumber (HWVN, 2800-3800 cm-1) spectral ranges using different lasers. Our Raman fiber optic probes are compatible with process-interfaces to be cleanable and to enable reaction monitoring in lab, pilot plant and run full automated process control.

 Reflection Fiber Probes

Reflection fiber optic probes are designed to measure diffuse and specular reflectance, backscatter, or fluorescence of solid, liquid, and powder samples. Reflection and backscatter measurements provide important quantitative information about chemical composition of a sample.

1.    Endoscopic Fiber Optic Reflection Probes

Endoscopic reflection fiber optic probe are designed to measure diffuse and specular reflectance, backscatter, or fluorescence for biomedical applications.

We offer endoscopic reflection probe with thinnest probe tip diameter (0.5mm) and unique “7+1” fiber bundle configuration.  Based on bifurcated fiber optic bundle construction with” Illuminating” leg to carry light from a source to a sample – and “Reading” Leg to carry reflected light to a spectrometer. Unlike traditional fiber arrangement in reflection probes, which have “6-around-1” – fiber bundle configuration, our probes have “7 around 1”. That’s because in such configuration signal/ noise ratio is much higher than in traditional ones. All illuminating fibers of our endoscopic reflection probes are metal coated that’s why cross-talk between the illuminating fibers is blocked, and in result signal/noise ratio is higher than in similar probes with fiber polymer coatings.

Our endoscopic reflection fiber probes are available with round-to-round (R/R) or round-to-line (R/L) design.

2.    Fiber Optic Reflection Probes

We offer a large variety of specially designed reflection & 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 reflection 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 reflection probes are with metal coating clad, that why cross-talk between the illuminating fibers is blocked, and in result – signal/noise ratio is higher than in similar probes with fiber polymer coatings. Our reflection fiber probes are available with two, three or four fiber legs, and round-to-round (R/R) or round-to-line (R/L) construction.
