Optics and optical engineering

modeling and simulation

Consultantnet base our designs on understanding the true nature of a system, often the most efficient method of achieving this is to create a theoretical model of the design and simulate its performance over the full operating range and tolerances. This philosophy underpins all of our work and allows us to take a risk averse approach to design problems.

Zeemax – can be used in a non-sequential ray tracing mode allowing us to design and anlyse any photometric or radiometric problem.Non-sequential ray-tracing has recently been used to model systems looking at back-scattered radiation from particulates in a fluid, predict the signal levels detected by a turbidity meter, design parametric and non-parametric reflectors, model unusal bulb arrangements and predict signal levels in an weld head quality meter.
Zeemax was originally developed to model classical sequential ray-tracing and such was its success that it has become a de facto standard for many industries. Easy to use and interface with, it permits the full analysis of any optical system, including aberration analysis, mtf performance, diffraction
Consultantnet can offer you the support of gifted optical designers with many years of experience in the design, analysis, and construction of optical systems. Finite Element Analysis

Femlab – allows us to address a whole raft of problems that are beyond the grasp of many designers – fluid flow, electrostatics, thermal analysis, micromechanics, structural mechanics can all be dealt with using this powerful tool. The software permits equation based modelling so even if your application is not covered explicitly by the standard templates we can adapt the code to solve the problem.

Mechanical CAD

Full 3-D mechanical design and layout facilities allow us to prepare realistic models of a new product, check tolerances, avoid clashes and determine the space envelope for the electronics.

The model on the right, prepared using Solidworks, highlighted some assembly problems arising from the position of the LCD screen (shown in green), this resulted in a design change before prototype manufacture, seen on the right.
