Spectroscopy & Photonics

Market-leading technologies and products which use light and optics to measure substances as well as create, change and measure light.


We are the world leader in miniature spectrometers. These are optical sensors and analysers which measure the quantity and colour of light to reveal what things are made of and to measure the amount of compounds present in a sample. They are widely used by research scientists and also have practical applications as sensors in products such as atmospheric pollution monitoring systems and cancer diagnosis.
