ATM Optical Design and Analysis Software
written by Massimo Riccardi
NEW 8.7 Version
(now supporting Tolerance Analysis )
My name is Massimo Riccardi I am an
italian Optical Designer and advanced Amateur Telescope Maker .
Many years ago, after mastering my optical knowledge, I felt the need of a program capable to perform SpotDiagrams for many wavelengths at the same time.
So, just for fun, in that period I tried to write a routine capable to perform such polichromatic Spotdiagrams using the only programming language I knew: QBASIC.
I did it and I succeeded and, as it often happens, I felt the need to improve it again by adding several analysis routines.
It was born the first version of "ATMOS" (ATM Optical design and analysis Software).
At that time it was for personal use only.
Then,unsatisfied with DOS & QBASIC capabilities, I chose a programming language that ran under MS-WINDOWS.
In this way I could get not only a better program "look" but most of all a user-friendly interface with many windows, buttons, textboxes where you can type the data or display the results.
So I rewrote ATMOS in Visual Basic and added much more analysis routines and useful telescope design tools.
ATMOS now is a very powerful program with a
user-friendly interface that allows the user to Analyze, Design and
OPTIMIZE Centered/Uncentered optical systems.
Atmos is appreciated worldwide by amateurs and professional users and is under continuous developement.
ATMOS supports up to 100 surfaces and Obscuration Screens. It includes a powerful routine for Optimization,adjustable Aperture Stop position and supports both Finite/Infinte Object Distance .It also displays an improved 2D, 3D-Layouts .

Jim Klein author of ODP
optical design software for his help and encouragement.
- ATMOS 8.7 Features
ATMOS 8.7 incorporates a wide range of features :
Centered and Uncentered
ANALYSIS (graphical and/or tabular)
TELESCOPE DESIGN Capability
One of the most useful and
pleasant tool for the ATM is the "Telescope Design"
You can easily and quickly design and then analyze about 30 optical configurations:
- ATMOS ANALYSIS SLIDES
The following are some screen
shots taken from ATMOS.
-LENS DATA EDITOR
-Polichromatic MULTI-SPOTDIAGRAM (through Focus/Field)
-STREHL Ratio versus WaveLength
-Diffraction POINT SPREAD FUNCTION (FFT method))
-Simulated Color Diffraction Image
-WAVEFRONT (3D rotation)
-Through focus MTF (Modulation Transfer Function)
-Longitudinal,Transversal SPHERICAL ABERRATION and COMA (Offense against the Sine Condition)
- 2D and 3D LAYOUTS
- Element DRAWINGS
- ATMOS TELESCOPE DESIGN SLIDES
Here are some screen shots from the "Telescope Design" Menu':

-TRIPLET DESIGN WINDOW

- Download ATMOS FreeWare
This is full function program, but limited up to 3 optical surfaces (except for the sample files). You can design and analyze with this version Newtonian and classical two mirror telescopes . This version will introduce you to the ATMOS interface and give you a feel for the features of the program Obviously,it cannot do everything the real program can.
ATMOS FREEWARE comes with 36 sample files, and you can load up and analyze any of them.
Download the following file:
ATMOS FreeWare - (about 4 MB)
After downloading "Atmos Demo.zip" , unzip it then double-click on "setup.exe" for ATMOS self-installation.
ATMOS can be delivered either via e-mail or on CD-ROM by postal air mail .
Delivery via e-mail is preferred.
