Spectrometers measure and analyse the spectral distribution of light, supporting the identification, characterisation and quantification of the optical, chemical and structural properties of materials. The APEL Laser portfolio includes compact, portable and laboratory spectrometers, high-resolution spectrographs, Raman systems and confocal Raman microscopes, together with solutions for absorption, transmission, reflection, emission, fluorescence, photoluminescence, LIBS and colour measurement.
