Evaporative Light Scattering Detector
ELSD-LTII
The ELSD-LTII utilizes a high-efficiency LED and enhanced digital signal treatment to minimize noise and deliver optimum sensitivity for trace analysis. An innovative cell design also reduces band broadening and allows sensitivity levels below 200 picograms. The high-performance optical detection system can also be used for combinatorial chemistry and high-throughput screening applications. The new Low Temperature Evaporative Light Scattering Detector (ELSD-LTII) is an easy-to-operate, universal detector that identifies analytes with uniform sensitivity regardless of their spectroscopic properties. It is not a spectroscopic detector. Instead, it removes the mobile phase through evaporation and then makes a light scattering measurement of the dried analyte particles.

SERS (Surface Enhanced Raman Scattering) Substrate & SERS Reader – Mini Chemistry Analytic Pack
The porous carbon SERS substrate provides not only high signal enhancement due to its strong broadband charge-transfer resonance for large chemical enhancement (as opposed to electromagnetic enhancement in traditional metal-based SERS substrates), but also extraordinarily high reproducibility or substrate-to-substrate, spot-to-spot, sample-to-sample, and time-to-time consistency in SERS spectrum (which is not possible with traditional metal-based SERS) due to the absence of "electromagnetic hot spots" by making the entire surface of the substrate "chemically hot", high durability due to no oxidization, and high compatibility to biomolecules due to its fluorescence quenching capability.

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.

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.

Deep Submersible Particle Size Analyzer
LISST-Deep
The LISST-DEEP instrument obtains in-situmeasurements of particle size distribution,optical transmission, and the opticalvolume scattering function (VSF). Using ared 670nm diode laser and a customsilicon detector, small-angle scatteringfrom suspended particles is sensed at 32specific log-spaced angle ranges. Thismeasurement is post-processed to obtainsediment size distribution, volumeconcentration, optical transmission, andVSF. The electronics and opticalconfiguration in the LISST-DEEP are verysimilar to Sequoia’s workhorse, the LISST-100X. However, because of the extremedifficulty associated with keepingalignment under high pressure, the LISSTDEEPhardware design is radically differentfrom the LISST-100X. This allows theLISST-DEEP to be deployed down to 3000m and obtain reliable measurements ofthe in situ particle size distribution andvolume concentration in waters withoptical transmission up to 98.5%.

Multi-Laser Nanoparticle Tracking Analysis (NTA)
ViewSizer 3000
Exosomes, viruses, and nanoparticles all have wide size distributions which defeat traditional Nanoparticle Tracking Analysis (NTA) analyzers. The ViewSizer 3000 features simultaneous measurement with three lasers to collect the most accurate distribution and concentration information over a wide range of sizes within the same sample. Where the signal from a particle is too bright and saturates the detector from one laser, the software automatically uses data from a lower power laser to ensure the most accurate size and concentration information. On the other hand, when scattering from one laser is too weak for detection, the software uses data from a higher power laser to accurately track the particle.

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.

Bending Deflectometers For ISO 178, JIS K 7171, And ASTM D790 Compliant Testing
After tensile testing, flexural tests are the most common strength tests for plastics and other resins. The main standards for plastic flexural (bend) tests are ISO 178, JIS K 7171, and ASTM D790, which require very accurate test systems. These standards include flexural strain measurements using a deflectometer, ranging from micro-strain measurements in the elastic region, the reversible elongation at the beginning of tests, to larger strain measurements in the plastic region. Shimadzu's deflectometers integrate easily into AG-X plus series, AGS-X series, and EZ-X test frames and Trapezium X testing software. Since these deflectometers push up against the specimen from below, the specimen color is not a limiting factor, as can be for laser type non-contact deflectometers. Furthermore, these deflectometers can partially absorb the shock during specimen failure, preventing specimen fragments from scattering.

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.

CATV Separate Raman Amplifier
RFA4000
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.
