Portable size thermal lens spectroscopy detection system "GRINSpectra"

What is "GRINSpectra"?

GRINSpectra

A portable thermal lens spectroscopy detection systems which has small dimensions and can be transported easily. The concentrations of target samples in a solution in a microchannel can be measured with a high sensitivity and stability without any special knowledge or skill.
NSG succeeded in miniaturizing Thermal Lens Microscope as portable size packaging of introducing NSG's long years' experiences in SELFOC® Micro Lens (SML) and fiber optic technologies against existing technologies of great bulk as desk top size. Together with smaller size packaging, NSG made great strides in optical stability. These advantages enable that accurate measurement can be carried out anywhere by easy transportation.
