(ATMOS87)

Now supporting Tolerance Analysis

ATMOS History

ATMOS Optical Design and Analysis Software is the creation of Massimo Riccardi, an Italian advanced Amateur Telescope Maker and designer. Mr. Riccardi has considerable experience with telescope designing and glassworking: Doublets, Triplets, Catadioptrics, etc. Several years ago, after mastering his optical knowledge, he felt the need for a program capable of producing SpotDiagrams for many wavelengths at the same time. So, just for fun, he tried to write a routine capable of producing such polychromatic Spotdiagrams using the only programming language he knew: QBASIC.

He succeeded and, as often happens, he felt the need to improve it again by adding several analysis routines. Thus, the first version of "ATMOS" (Amateur Telescope Maker Optical design and analysis Software) was born. At that time it was for personal use only.

Then, dissatisfied with DOS & QBASIC capabilities, he chose a programming language that ran under MS-WINDOWS. In this way he could get not only a better looking program, but most of all, a user-friendly interface with many windows, buttons and textboxes where the user could type the data or display the results. He rewrote ATMOS in Visual Basic and added many more analysis routines and useful telescope design tools.

ATMOS now is a powerful program with a user-friendly interface that allows the user to Analyze, Design and OPTIMIZE Centered/Uncentered optical systems and it is avalaible at a very affordable price. ATMOS is appreciated by amateurs and professional users and is under continuous development.

The current ATMOS version 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 improved 2D, 3D-Layouts .

Mr. Riccardi wishes to thank :

ROLAND CHRISTEN the owner of the well-known telescopes firm "Astro-Physics"

Fritz Blechinger, a professional designer, author of OpTalix optical software

Rick Blakley for his patience in testing my software

Ivan Krastev, author of MODAS optical software for the common work and suggestions exchanged over the last years

Cor Berrevoets author of ABERRATOR

Jim Klein author of ODP optical design software for his help and encouragement

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:

Newtonian
Two Mirrors (All Cassegrain types, all Richey-Chretiens, all Gregorian types,Couder-Schwarzschield)
Schmidt and Wright cameras
Schmidt Cassegrain (compact and no-compact Schmidt-Cass. types, Monocentric Schmidt-Cass.)
Maksutov (new design window)
Maksutov-Cassegrain (new design window)
Lurie-Houghton (all-spherical and aspherical types)
Houghton-Cassegrain (all-spherical and aspherical types)
Doublets
Triplets

System Requirements

Windows XP / Vista / Windows 7 are the preferred operating systems for this software. Computers with faster Core Processors and increased RAM will perform better.

Download ATMOS Demo

This is the full function program, but has been limited to just 3 optical surfaces (except for the sample files). You can design and analyze Newtonian and classical two mirror telescopes with this version. This demo 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 Freeware.zip" , unzip it then double-click on "setup.exe" for ATMOS self-installation.
