In 1861 in France, the chemist Alphonse Louis POITOUIN discovers a process based on the rays of the sun and a substance present in the gum. The result of such an improvement is a faithful reproduction of original architectural drawings. Few years after this discovery comes the Second Industrial Revolution and its share of technologic upheaval!


In 1936, the English code deciphers Alan Turing invents a machine bearing his name, which foreshadows the modern computer. 


In the 40's/50's the mainframe computer is marketed. In 1955, transients increase exponentially the processing speed. 


In 1961, Dr. Patrick J. HANRATTY works for the General Motors research laboratories and develop the DAC. The same year, Douglas T. ROSS will call it CAD. Ten years later, P.HANRATTY introduces a CAD software called " Automated Drafting And Machinery " (ADAM). Although, 90% of the drawing software today have a link with ADAM. In 1977, CATIA, the first 3D CAD system is launched! In 1985, modeling is introduced, paving the way for digital prototyping. 


In 1989, Jacques Delacour creates OPTIS, a photometric & laser propagation company. Very quickly, the big names in the Industry are seduced by SPEOS: a software dedicated to the simulation of light in any optical system. OPTIS is aware of the necessity to couple the use of SPEOS with CAD platforms, to model the products of tomorrow before incorporating light and materials into 3D models. 


In 2001, SPEOS is integrated into CATIA V5. Then, it will be integrated into SOLIDWORKS® in 2002, PTC Creo in 2009 & Siemens NX in 2014 to maximize the number of users!



In 2017, OPTIS has sold more than 8100 licenses of its software, integrated into the most popular CAD platforms in the world!


The OPTIS Team is present at the SIEMENS PLM CONNECTION 2017 as a partner to show how the integration of its solutions in the most famous CAD platforms, such as Siemens NX, makes it possible to create ultra-realistic prototypes that are used as real decision tools for industries!
