%X To solve the problem that the traditional optical absorption cell can not meet the requirement of low cost while meets the requirement of high optical spot density, a new optical absorption cell combining spherical mirrors with astigmatic mirrors is designed according to the transfer matrix formalism. The relationship of the beam transmission number in the optical absorption cell with structure parameters, mirror rotation and emergent light slope is analyzed by numerical simulation. The results show that the combination of spherical mirrors with astigmatic mirrors has a good anti-interference capability. A design example for an optical absorption cell with the length of 65 mm and an optical path of 10 m is given. This optical absorption cell has a small interference effect. Its volume is merely 0.29 L. It is suitable for absorption spectroscopy.
