Multi or hyperspectral camera to maintain the lateral magnification adjusting the focus that includes, in a box (4) at least 4 sensors (2), a lens (3) for each sensor (2), an external band pass filter (14) for each sensor (2), a calibration matrix, a battery (5) to provide energy, standardized tapes (7) for sending information to a microchip (8), a motor (16) for each sensor (2) so that the sensor (2), the lens (3) and the band-pass filter (14) move in unison to focus while maintaining the lateral magnification, where the multispectral camera is called the one that includes between 4 and 15 sensors (2) and hyperspectral camera which includes at least 16 sensors (2). These cameras with an external filter matrix are useful for registering multiple spectra emitted or reflected by an object or light source in a single optoelectronic device, with the option of manufacturing it as a universal structure thanks to using the dimensions and characteristics of a conventional camera.
