    Abstract: The imaging spectrograph comprises of the first optical system (104), the spectral filter unit, the second optical system (124), and the detector (114). The spectral filter unit comprises of at least one optical filter (110), which position to both optical systems (104, 124) satisfies the conditions zz?=ff? and zz?=ff? where z is the distance between the object (102) and the front focal point of the first optical system (104), z? is the distance between the optical filter (110) and the rear focal point of the first optical system (104), f and f? are the front and rear focal lengths of the first optical system (104), respectively, Z is the distance between the optical filter (110) and the front focal point of the second optical system (124), z? is the distance between the photosensitive area of the detector (114) and the rear focal point of the second optical system (124), and f and f? are the front and rear focal lengths of the second optical system (124), respectively.
