Abstract
A reflective telecentric lens which uses an on-axis type concave mirror in a pseudo-off-axis manner to avoid blockage of a portion of the field of view. The concave mirror used in a pseudo-off-axis manner permits the telecentric stop, imaging lens, and film or an electronic detector to be moved outside of the field of view.
