From the Website of Ocean Optics, an applications note for their Jaz Spectrometer
“Reflectance spectroscopy is a versatile technique than can be used to identify and characterize a range of powdered samples including mineral powders, grains in lunar samples, mining samples, natural deposits, soils and sediment core samples. In this application note, reflectance spectroscopy is used to characterize mineral powder samples.
“The Jaz spectrometer was used to acquire reflectance spectra for pure samples and powder mixtures to assess the power of reflectance spectroscopy to characterize mineral powder samples.”

Recent studies about non-contact temperature measurement concern passive multiband radiometric systems. These systems give a potential possibility of accurate temperature measurements in case of unknown and wavelength depended emissivity of the examined object. Modeling of such systems, what is usually the first stage of system designing, requires acceptance of several simplifications and approximations. In this paper an experimental verification of modeling result is performed. Based on developed experimental setup some tests are performed. It allows us to determine some systems parameters and whole system estimation.Read More

During last decade an increasing interest in passive multiband systems for temperature measurement was noted. However, recent studies showed that multiband systems are capable of producing accurate results of non-contact temperature measurement only in limited number of applications. Available literature about passive multiband systems concentrated exclusively on problem of temperature measurements too. A model of a passive multiband system for non-contact emissivity measurement has been developed and presented in this paper. Simulations carried out using this model showed that it is possible to achieve reasonable accuracy of emissivity measurements with passive multiband systems and these systems can be considered as an attractive solution for emissivity measurements in industrial conditions.Read More
This site and a few others on our network were hacked recently and we have just begun recovery.
Thank you for your patience.
For those of you who are interested in the details of the attack and our recovery, I will be publishing shortly a link to them and the help and lack of help received by the various web hosting services that we have been using.
This is a way of praise for some and a word of warning about the others.
