Optical & Chemical Software Archive — Public Domain Legacy Project

About the Project

METEC USA, Inc. was founded in 1994 by a group of engineers and scientists from Massachusetts, USA and St. Petersburg. The company specialized in the development of highly specialized software and simulation tools for various branches of science, engineering, and education.

Today, this website serves as a permanent open-source and free archive to preserve the innovative tools developed by the company, making them freely available to scientists, engineers, educators, and students worldwide as public domain legacy software.

Documentation & Examples

VOB Series Features

VOB PRO and VOB ++ were designed to address the needs of professional lens designers, electro-optical engineers, and students. Key features include:

VOB ++: A virtual lab bench simulating target-to-detector electro-optical systems, array/scanning detectors, and noise control. Excellent for advanced physics and optics courses.
VOB PRO: Adds Local System Optimization and Holographic Optical Elements (HOE). Optimization is controlled directly from spreadsheet tables.

System Requirements (Legacy)

Windows 95/98/NT 4.0, Windows 2000 or Windows XP
Pentium-class processor (100 MHz or faster)
16 MB to 64 MB RAM
SVGA Display (256 colors or more)
10 MB to 40 MB available hard disk space

Molecular Design Studio "ONYX" (MDS)

Molecular Design Studio "ONYX" is a rules-based rules simulation software specifically built for chemical education. It serves as a perfect tool for teachers and students in general and organic chemistry.

Core Functionality:

Constructing 3-dimensional molecules, ions, and complex compound crystal lattices.
Modeling covalent bonds based on VSEPR and Valence Bond theories.
Animating chemical reactions and molecular modeling in real-time.
Automatic calculation of valence angles, charges, formal charges, and atomic oxidation states.
Built-in database containing van der Waals radii, ground states of valence orbitals, and electronegativities.

Legacy OS Compatibility: Windows 98 / ME / NT / 2000.
