High-performance Multispectral Camera System
The new high-performance multispectral camera system by Fujifilm is the first multispectral camera to adopt a polarization system, capable of simultaneously capturing spectral image up to nine wavelength bands in high definition and presenting the image in real time.

There are high expectations for the applications of multispectral camera systems in a wide range of industries. In response, Fujifilm has developed a multispectral camera system based on a polarization system, tapping into its optical technology, nurtured through the development of 4K/8K broadcast lenses and a wide range of other lens products, as well as the cutting-edge image processing technology nurtured through the development of the GFX/X Series of digital cameras. The high-performance multispectral camera system is equipped with a lens fitted with newly-developed filters, a polarization image sensor that can capture specific directional polarization image, and a cutting-edge image processing function. The camera system can simultaneously record images of different wavelength ranges in high definition and presenting them in real time. The newly-developed filters serve as polarizer that lets light in a specific direction of polarization pass through as well as optical bandpass filter that passes light of a specific wavelength range. The system uses three filters to split light into up to nine wavelength bands, while also polarizing the light of each wavelength band into a specific oscillation direction. The polarization information of light in each wavelength band that has passed through the filters is recorded by the polarization image sensor and applied with the cutting-edge image processing function for visual presentation in high resolution and at a high frame rate. The system also allows users to choose an optical bandpass filter of the optimum wavelength band for their monitoring object. The camera system is currently just a prototype and not yet a finished product ready for the market.
