Smaet LDV III
-
A Laser Doppler Velocimeter (LDV) measures fluid velocity by utilizing coherence of laser light. It detects the Doppler shift frequency of the scattering light of particles in the fluid and calculates the velocity of the particles (fluid). With a LDV system, non-intrusive measurements without disturbing the measuring object, liquid or gas flow, are achieved. No calibration is necessary and reverse flow measurements at a high resolution is also possible. The LDV system provides the absolute value of the flow velocity with accuracy.

Hangzhou Huatai Optic Tech. Co., Ltd.
1. Erbium-doped Fiber Amplifier, due to the multiple cascades and the accumulation of noise caused by spontaneous emission, will reduce the system CNR greatly and thus it will limit the transmission capacity and distance of the system. Raman Amplifier is a newly designed fiber amplifier based on Stimulated Raman Scattering (SRS) effect. Raman amplifier is considered as the core technology of new generation DWDM fiber over-long communication. Compared with Erbium-Doped Fiber Amplifier, Raman amplifier has the advantage of low Noise Figure (NF), wider gain bandwidth, flexible gain spectral region and stable temperature. It is the only device that can operate in 1300~1600 nm.

Raman Probes
-
As with Raman spectrometers, a Raman probe is used to measure the inelastic scattering of light from a sample. Raman scattering is produced when the energy levels of photons are shifted up or down as a result of excitation by a monochromatic source (usually a laser). The change in vibrational frequency is used to determine the composition of a target substance.

Gloss & Reflectance
-
Visual appearance can determine a person’s perception of a product. Colour and Gloss are two key parameters that are used to define a product’s overall quality. Perception is subjective, but Elcometer’s range of gloss meters, DOI meters and colour assessment equipment can quantify appearance measurement. The ability of a surface to reflect light without scattering is known as gloss. Using a gloss meter, gloss is measured by directing a constant intensity light beam at a fixed angle to the test surface and then by monitoring the amount of reflected light at the same angle. Different surfaces require different reflective angles.

Saybolt Color Analyzer
-
optek’s Saybolt color analyzer is a dual wavelength light absorption sensor. Operationally, the sensor passes a white light beam through the stream to be monitored, where light absorbance is measured at two distinct wavelengths. The measuring wavelength is set to focus on or near the peak absorbance point of the “yellowness” curve, while the secondary wavelength is chosen to compensate for any influence due to light scattering (window fouling, particulate, immiscible fluids, gas bubbles, etc.). Together, the sensor yields a repeatable and reliable true color number without any sample conditioning.

Turbidity Sensors
-
Turbidity sensors measure the amount of light that is scattered by the suspended solids in water. As the amount of total suspended solids (TSS) in water increases, the water's turbidity level (and cloudiness or haziness) increases. Turbidity sensors are used in river and stream gaging, wastewater and effluent measurements, control instrumentation for settling ponds, sediment transport research, and laboratory measurements.

Raman Spectroscopy
-
Raman is a spectroscopic technique that uses laser light to interact with molecular excitations and determine what a substance or element is composed of. It relies upon the inelastic scattering of photons which produces a weak signal, making the collection of information challenging particularly when the substance to be measured is at distance or can only be given short exposure times. Our Raman spectrometers are particularly effective at making Raman measurements due to their configuration which delivers a higher throughput/etendue than standard instruments.

Optical Time Domain Reflectometers
-
An optical time domain reflectometer (OTDR) is a precision instrument used to locate events or faults along a fiber link, typically within an optical communications network. The OTDR launches a series of high speed optical pulses into the fiber to be measured. Various events on the fiber generates a Rayleigh back scatter that returns to the OTDR and the strength of the return pulses are measured and integrated as a function of time, and plotted as a function of fiber length. The horizontal axis is the distance and the vertical axis is the loss.
