Abstract: The asymptotic behaviour of even canonical products with zeros on the real axis is considered. It is assumed that the set of zeros has density (the sequence $\pm \lambda_{n}$ has density). Sharp asymptotic estimates for the logarithm of the modulus of the canonical product are obtained under certain restrictions on the rate of convergence of the ratio $n/\lambda_{n}$ to its limit.

Keywords: even canonical product, regularly varying function, asymptotic estimate.
