Based on the classification of the large optical/infrared telescopes, which are with apertures about 10 m, this paper suggests a novel concept design for a 10 m optical/infrared telescope. The new 10 m telescope proposed in this paper has its own characteristics. Its focal ratio is 1.7, the field of view is about 6 to 8 arcmin, satisfying both high resolution spectroscopic and imaging observations. Its observing sky coverage can be 100° (range of the declination angle). The primary mirror of this new 10 m telescope is composed of 91 hexagonal sub-mirrors, which are with the diagonal diameter of 1.2 m. During observation in the optical band, the co-phase of the 91 sub-mirrors will not be required, but the co-focus will be necessary. The conclusion of this paper is that the new 10 m telescope is a low cost (about 1300 to 2000) and low risk new generation large optical/infrared telescope.
