CMOS and its application in spectroscopy

contributed by Hamamatsu | 04/16/2025

Spectroscopy examines how matter interacts with electromagnetic radiation, revealing a substance’s composition, structure, and physical properties. This essential technique is widely used in chemistry, physics, astronomy, and biology, with applications ranging from water analysis and identifying chemical compositions to studying astronomical objects. A vital component of spectroscopy instruments, and techniques, such as Raman spectroscopy, is the image sensor, with CMOS sensors gaining prominence for their ease of integration, high sensitivity, and capability for high-speed data acquisition. This has made the CMOS image sensor increasingly popular in spectroscopy.
