Instrumentation

Spectromics Laboratory has a versatile instrumentation that has high spatial and spectral resolution with an exceptionally wide wavelength range (250 - 5000 nm). Imaging techniques enable noninvasive measurements with semi-high throughput levels, while microscopic applications are also possible. Several of the techniques can be transferred from the laboratory to the field.
