A three-channel spectrometer including: a beamsplitter element that receives an incident radiation and transmits a first portion, a second portion, and a third portion of the incident radiation, a first slit that receives the first portion and transmits a first slit output radiation of a first wavelength range; a second slit that receives the second portion and transmits a second slit output radiation of a second wavelength range; a third slit that receives the third portion of the incident radiation and transmits a third slit output radiation of a third wavelength range; a common optical form that receives and collimates the first, second, and third slit output radiation; and a dispersive element that receives and reflects the collimated first, second, and third slit output radiation from the optical form. |
