Abstract. A technology of centering IR lenses with one aspherical surface is considered. The centering procedure is combined with shaping the aspherical surface on a diamond micro-turning machine. Recommendations are given on setting tolerances for lens thickness and air gaps in IR lenses when using this technology.
Keywords: lens centering, diamond turning, aspherical surface, IR optomechanical system, IR objective
