title: CLIMB: a new Los Alamos Scientific Laboratory lens design code.
abstract: The new LASL lens design code uses a Monte Carlo random selection of object points in the object field, each with a ray of specified color traced through a randomly selected point in the entrance pupil. The figure of merit is measured by the failure of the designer's mapping unction, including constraints, to predict the actual ray trace position at the focal surface or elsewhere in the optical system. Optical system layout flexibility has been increased by allowing (1) the coordinate system to move with the central ray during designing, (2) the introduction of an accessory reference surface anywhere in the system, and (3) the specification of an optical surface by a table of surface coordinates.
