ATM Optical Design and Analysis Software
by Massimo Riccardi

Italian amateur Massimo Riccardi has developed an easy to use optical design program, loaded with powerful routines and analysis windows to design and evaluate the most advanced optical systems. It is aimed at amateurs who like to dabble in telescope design or who just like to explore the world of optics. Starting routines for the most common and favorite telescope systems makes it easy to design the basic system in minutes with just a few parameters. A powerful optimization routine can then be used to vary any number of surfaces to get the most ideal result.

Telescope Design Capability

One of the most useful and pleasant tool for the ATM is the "Telescope Design" Menu.
You can easily and quickly design and then analyze about 30 optical configurations:
