Dear Customers and Partners,


We are pleased to announce that SPEOS CAA V5 Based V16.0 is now available!


This new version includes Photometric targets created in the sensor allowing for faster simulations enhancing users productivity.


Ergonomics of simulation settings and result analysis are improved thanks to geometry groups and local meshing.


SPEOS CAA V5 Based V16.0 OSD users will enjoy new functionality including Interactive Real-Time Photometric analysis during Optical design.


Freeform elements such as Curved Prisms on Optical Lenses or Light Guides are an amazing way to control light.



We really hope you will enjoy this new version of SPEOS CAA V5 Based !


If you have any questions, please contact your local Optis subsidiary.

Productivity efficiency
Interactive Photometry

Optical Shape Design

In addition to the beam shape and source images, Optical Surface can now  interactively display an approximated intensity distribution of the selected elements.


Therefore, designers immediately have the understanding of photometric behavior of the surface and thus the ability to adjust the shape parameters to interactively optimize the design.


Punctual source will be supported in a future version.

Optical efficiency
Light Control

Optical Shape Design

The free form type of Optical Surface feature has been enhanced to manage target distribution.


Users can now control light with better control with an easy to use interface.


Optical design can be adjusted to closely fit with targets without any light losses.

Headlamp design

Sharp cut off element

Optical Shape Design

Thanks to sharp cut-off in Optical Surface, ECE R112 LB can be achieved with
15° cut-off even with pure vertical stripes.


Using OSD, required time for design is drastically reduced, what took days now takes minutes.

Vertical stripes

No oblique element for 15°cutoff





Productivity efficiency Mechanical design

Optical surface with circular grid and radial shift now has the possibility to add automatic sewing.


This operation is done in a couple of seconds instead of several human-days of hand work.


Automatic sewing is a great improvement for your productivity.

Optical efficiency

Removed prism

Optical Shape Design

On Light Guide, it is now possible to change building type for Removed prisms.


This can be usefull to improve light guide efficiency.


With removed prism, average luminance is increased by a 10x factor. It offers higher performance or a cheaper LED lighting system.



Operation : Add


Operation : Remove


Optical efficiency

Lit aspect improvement

Optical Shape Design

On Light Guide feature, Curved prisms are now available.


With Curved prism, Light is spread around an optical axis, therefore lit aspect is improved from different viewing directions.





Flat Prism


Curved Prism (radius 1.5mm)


Productivity efficiency

New feature : Pyramid prisms

New option on Optical Lens feature.


In addition to Prism and Pillow, you can now select Pyramid prisms.


The end-customer will not see inside your transparent product.

Optical Shape Design

These elements are generated automatically in a few seconds compared to previously in several days when manually done.


Optical efficiency

Curved prism

Optical Shape Design

On Optical Lens, Curved prism can be created to spread light on beam pattern.

Affording users better control of light to easily reach photometry target.



Productivity & Ergonomics

Measurement template

Intensity map view


Management of Multi-Measure in a comprehensive view has been introduced on previous SPEOS version. It saves time during iteration process.


Measure template can now be set from sensor definition. Measures are directly shown on an intuitive and easy to read  HTML simulation report.

Measures & Rules


Simulation Wizard  option(OPTIM1) offers automatic task capability to increase quality and performances of your design.


From measure templates, rules allows to check conformity of standard regulation or Customer specification. You can immediatly check margin for each point.


Measurement rules can be set from VP Lab or HV Lab and can be shared with other SPEOS users. This offers standardisation of reports coming from your different entities.


Measures and rules are directly shown on an intuitive and easy to read  HTML simulation report.

Productivity & Ergonomics

Knowledge / OPTIM / PLM

In addition to extended HTML simulation reports, Measures and Rules are shown in CATIA V5 3D tree and can be used during optimization of your designs.


Making it easy to evaluate any modification coming from other department (Style, integration).


Offering a full integration in PLM without any external tool.


Report, Numerical Validation are connected with CATIA V5.


Optimization and tolerancing target available in one click, being directly feed by measures.





Productivity : Direct 2D illuminance simulation

Road Lighting Validation Scene

2 headlamps

In the case of a simple configuration system (direct light from source to sensor without reflection) such as luminaire or headlamps lighting a road, Illuminance maps are simulated in a couple of seconds without noise.

Direct 2D illuminance simulation

10 secondes, high quality result

Direct simulation

100 millions rays, 20 minutes, noise on result

More productivity is offered thanks to fast and accurate simulation.


Compared to direct simulation, Direct 2D illuminance Simulations are more than 100x faster with high quality results.



Productivity :

Local meshing

Local meshing is introduced for complex systems requiring different meshing definitions.


Simulations are faster without any impact on quality results.


When selected, local meshing can directly be seen on 3D View.


No limitations of local meshing entities.

Step Value = 1


Local meshing on windshield :

Step Value = 20

Ergonomic : Face Optical Visualization

Face Optical Properties allow users to create specific optical settings for individual faces.


Visualization has been improved to be more visible in 3D View. Instead of dotted surfaces, FOP are now shown with uniform color.

On complex system coming from different departments, FOP can be directly visible before launching simulations.



Productivity & Ergonomic

Geometry Group

Geometry group allows users to save time during simulation preparation and analysis.


Local meshing and Face Optical Properties can be applied on Geometry groups.

Light Expert Analysis with Geometry Group in Surface Contribution Analysis is easier to navigate and understand.

New functionality : Save spectrum for illuminance

New Spectral type introduced for illuminance, intensity and radiance sensor with direct or inverse simulation. Spectrum information are stored only for this type of sensor.


Colorimetric type is used to stored only XYZ information. Compared to fine wavelength resolution, XMP files can be 80x lighter. During DIstributed Simulation no time is lost merging results.




Human Vision

Color Visual deficiency

Roughly 8% of men and 0.5% of women are affected by color visual deficiency.


This effects 5% of your customer base relating to perceived quality & security issues.
