Metamaterials webinar on Thursday sponsored by CRAIC Technologies – the Microspectroscopy People

CRAIC Technologies are sponsoring a webinar entitled Metamaterials Design and Characterization with UV–VIS–NIR Microspectroscopy. It is being hosted by PhysicsWorld, and takes place this Thursday, November 14th at 3pm GMT.

Dr Yash Shah

Briefly, Dr Yash Shah from the Xtreme Light Group at Glasgow University will talk about creating polarisation-insensitive plasmonic filters with narrow linewidths, and his novel experiments conducted with a microspectrophotometer to collect Stokes polarimetry measurements.

Dr Jon Burdett – lead applications scientist at CRAIC Technologies – will introduce CRAIC’s microspectrophotometers and advise on microspectrophotometer experiments.

CRAIC Technologies launch GeoImage™ for petrographic analysis

GeoImage™ is the latest Vitrinite Reflectance Measurement System from CRAIC Technologies and is used to determine the grade of coal and coke by vitrinite reflectance as per the ISO 7404-5 and ASTM D2798 standards. These procedures ensure that coal blends used in energy generation and steel making are optimal and consistent from batch to batch.

Designed for use with petrographic microscopes, GeoImage™ can also be used in conjunction with CRAIC’s microspectrometers to also acquire reflectance and fluorescence spectra of coal samples, and take high resolution colour images too.

GeoImage™ also features an automated point counting module where hundreds of points are measured on the sample. Using statistical data analysis, the amount of vitrinite* in the coal blend, its thermal maturity and thus its energy content can be quickly determined.

For more information about GeoImage™ and other products from CRAIC Technologies, please contact us.

* Vitrinite is a maceral of coal and is comprised of various polymers, cellulose and lignin. Measuring the amount of light reflected by vitrinite macerals is a key test to determine the thermal maturity of the coal blend and its suitability for steel production. The procedure has been standardised by a number of international bodies including both ISO and ASTM.
