Abstract: A single aperture three channel optical system is disclosed. In one embodiment, the optical system includes a front optical group and a back optical group that is disposed in substantially close proximity to the front optical group. Further, the optical system includes a first sensor, a second sensor, and a third sensor. The front optical group and the second optical group receives an object beam and splits into a reflected beam having first wavelengths and a transmitted beam of second wavelengths. Furthermore, the front optical group and the second optical group splits the reflected beam having first wavelengths into a transmitted beam having third wavelengths and a reflected beam having fourth wavelengths. The first sensor, the second sensor and the third sensor receive the transmitted beam of second wavelengths, transmitted beam of third wavelengths, and reflected beam of fourth wavelengths, respectively and produce the coaxial three channel images.
