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.

Gamma Detectors
-
In Gamma detectors, the gamma radiations produce electrons by interacting with the cathode material and the filling gas.These electrons ionize the gas and the charge carriers are collected by the electrodes. The resulting anode pulse is detected by a load circuit. The primary electrons are created by several interaction mechanisms:- Photoelectric effect- Compton scattering- Pair production

Light-resistant Integrating Sphere
-
The integrating sphere is used for total luminous flux measurement. It uniforms the light by spatially integrating the collected light of light source. The integrating sphere has highly reflective diffusing plates formed on the spheres internal surfaces. These plates repeatedly scatter light rays from the light source with in the sphere to all other points to deliver uniform brightness distribution so measuring a portion of that light gives the total luminous flux. These years, the usage of integrating sphere for total luminous flux evaluation of light source is increasing. The large size integrating sphere over 1.5M is required for measuring a high brightness light source and a long light source such as fluorescent light.

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%.

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.

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.

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.

Logger Version 2-D Electro-Magnetic Current Meter for Deep Ocean
INFINITY-Deep AEMD-USB
-
INFINITY-Deep is an autonomously deployable data logger for current speed measurements in the deep oceans. The currents in the deep oceans are very weak. It is too hard to accurately measure the deep water currents by some ADVs (Acoustic Doppler Velocimeters) that detect the Doppler-effect by scatter with the suspended particles in the water, because the concentration is very low. INFINITY-Deep measures 2-D current data through a magnetic field according to Faraday's law. Therefore, even if the suspended particles do not exist around the sensor, it can provide the accurate current data. The depth rating is 6,000m. Compared to INFINITY-EM, the instrument has a depth and a tilt sensors to monitor mooring status. Also, the battery capacity doubles for long-term current velocity measurements.
