Hamamatsu Photonics has developed a palm-sized FT-NIR engine with a wavelength range from 1100 nm to 2500 nm. The model C15511-01 is built using Hamamatsu’s own microelectro-mechanical systems (MEMS) technology. Optical components such as the moving and fixed mirrors have been in a compact orientation that also minimises the error in the relative angle between the mirrors. The moving mirror is only 3 mm in diameter. The FT-NIR engine can help in creating handheld FT-NIR spectrophotometers for analytical applications including real-time monitoring of chemicals on production lines and ingredient analysis of agricultural products in the field.
