Ocean Optics Announces 2011 Video and Photo Contest Winners
After several months of competition, Ocean Optics (USA) has chosen the winners of its 2011 global video and photo contest. The Grand Prize in the video category was awarded to John Giddings, for his entry Telelumen at Mt. Fuji Summit, GOT IT!. In the photo category, Field Plot of Dreams, submitted by Mina Talajoor, took the Grand Prize.
To create the winning video, Giddings made an arduous two- day trek to the summit of Japan’s Mt. Fuji. Using two Ocean Optics’
USB4000 spectrometers he captured spectral data of the light at the top of the summit from dawn to dusk over three days. The short video captures Giddings’ first impressions of the “Spiritual Light” of the Mt. Fuji sunrise -the fabled sunrise which earned Japan the moniker “The Land of the Rising Sun.”
Axel Emmermann (a repeat Runner-Up winner from 2010), was awarded the First Runner-Up video prize for Jaz - The Versatile One, demonstrating how to customize the slit size on Ocean Optics’ Jaz spectrometer. Winner of the Runner-Up prize, Bill Hughes, enlisted the help of his students at Park Forest Middle School to create The Archaic Technology Blues, illustrating the need for Ocean Optics’ equipment to engage his tech- savvy students.
The Grand Prize photo, Field Plot of Dreams, from Mina Talajoor and researchers Duke Pauli and Jay Kalous, documents a project aimed at combating world hunger. Using the Jaz spectrometer, the group is measuring light reflected off the canopies of wheat and barley to identify plants with the most advantageous characteristics for breeding.

Diffusion Tubes for Trace Concentration Standards of Solids and Viscous Liquids
Diffusion Tubes have been used for many years as an inexpensive, do-it-yourself way to dynamically blend trace concentration gas mixtures for a large number of common solvents. Typical diffusion tubes have a glass reservoir attached to the end of a precision bore capillary tube. Solvent liquid is injected into the reservoir through the capillary bore. Solvent emission is controlled by diffusive flow through the capillary and adjusted by choice of capillary bore, length and operating temperature.
KIN-TEK’s (USA) Trace Source™ Configurable Diffusion Tubes extend the range of compounds that can be used to include subliming solids and viscous liquids. These tubes have a removable reservoir that allows filling with the capillary removed, so the component compound can be any consistency. Additionally, a variety of pre- configured and tested capillaries can be interchangeably fitted to the reservoir adjust the range of concentrations obtainable.
Multiple tubes can be used simultaneously in the FlexStream™ Automated Gas Standards Generating System to create multi-component gas mixtures.

Soil Moisture plus Temperature Sensor
The SM300 from Delta-T Devices (UK) measures soil moisture and temperature with research grade accuracy.
The SM300 offers outstanding performance in mineral, organic and saline soil conditions, and it is stable across wide ranges of temperature and salinity. The SM300’s construction uses industrial grade connectors and high specification materials throughout to produce a soil moisture sensor of outstanding quality. The built-in temperature sensor simplifies soil temperature measurement and achieves 0.5°C accuracy.
The SM300 minimises soil disturbance, preserving the original soil structure around the measurement rods. It is easy to insert and install whether at the soil surface or at depth. The SM300’s circular shape facilitates installation in augered holes – extension tubes are available.
The SM300 is a dual-purpose probe – it can be used both with the Delta-T HH2 hand-held Moisture Meter for instant moisture readings, or left in situ for data logging of moisture and temperature.
The SM300 is compatible with all Delta-T data loggers; they provide cost effective solutions for recording up to 60 sensors. In fact the SM300 can be connected to most types of data logger (simple 0 to 1V DC output for water content).

New Digital Economy Polarimeter
Kruss Optronic (Germany) are very proud of their Polarimeter P8000 because "it’s the fastest polarimeter worldwide!". Krüss developed a high-speed measurement that reduces measuring time to just 1 second irrespective of the angle of the sample.
The P3000 operates just as fast as its big brother; an intuitive touch screen with basic functions has been implemented as well.
For industries or applications which don’t need more than 2 digits after the decimal point and perform standardised measuring, the P3000 offers excellent value for money!
