The main features of OpTaliX are geometrical and diffraction analysis, optimization, thin film multilayer analysis and refinement, non-sequential ray trace, physical optics propagation, polarization analysis, ghost imaging, tolerance analysis, extensive manufacturing support, user defined graphics, macros, and many more. OpTaliX is available in three versions called OpTaliX-Pro, OpTaliX-Edu and OpTaliX-LT.

OpTaliX-LT is the shareware version of OpTaliX-Pro. It offers a subset of the features found in OpTaliX-Pro allowing geometrical analysis, but OpTaliX-LT does not contain the advanced Pro-features, like diffraction analysis, optimization, tolerance analysis, coatings, etc. However, it includes the full unrestricted raytrace code of OpTaliX-Pro and it is not crippled in type or number of surfaces.

OpTaliX-LT may also be used as a file converter for optical design programs such as CODE V, OSLO and ZEMAX. Also the file formats of ACCOS, WINLENS, SIGMA2000 and those of amateur programs like MODAS, ATMOS and ABERRATOR are supported. This feature supports the lens designers need to transfer lens design prescriptions from their preferred optical design package to another program.

DoubletCalc supports seven glass catalogues: Hoya, Ohara, Schott, Sumita, Corning, Special and Rutten Schott. The calculator can additionally plot the glass dispersion; i.e. shows how the glass refractive index varies with the wavelength changes.

It makes it possible to better understand the role of each optical component and to check the viability of the system. It is indeed possible that certain optical combinations turn out to be ineffective altogether. CORO announces it and indicates how work it out.

Extended HTML help included.

Note: The program is included due to the originality and specificity of purpose. Be warned tough that it may consume you some patience to put it work: namely with non French Windows installations (missing the Visual Basic French Language DLL) and specifically with XP. Brief instructions on how to solve this problem - if you stumble into it - are provided in the homepage.

Opus computes AKA "traces" the path of light "rays" from an "entrance-aperture" or "object-plane", through a series of "optical surfaces" (lens-surfaces, mirror-surfaces, vignette-stops) to a focal surface, where opus computes image error "aberrations" at several "field-angles" and colors AKA "wavelengths".

The optical system can contain up to 20 surfaces including plane surfaces, spherical, parabolic, elliptic, hyperbolic, Schmidt, as well as obstructions and diaphragms. One can conceive all types of instruments used by amateurs: Newton, Cassegrain, Schmidt, Maksutov, using all types of glasses and even instruments with components tilted and shifted like Schiefspiegler. One can define up to 9 types of different glasses for the systems where there is refraction.

The beam can be monochromic or composed of three colors. One can choose the colors (wavelengths) contained in the beam. The image obtained contains the colors of the beam and can show the chromatic aberrations. These chromatic aberrations are also shown in the graph of the longitudinal aberrations. Once the system buit, the software calculates the effective focal distance, geometrical and photographic F/D ratios, as well as the percentage of vignetting.
