Focusing and Collimation
The complementary optical functions focusing and collimation are directly or indirectly involved in almost any optical system. It is well known that ray tracing is not suitable for investigating focal regions. That makes wave-optical techniques important for the analysis and design of focusing systems. A proper definition of light sources is a prerequisite for the analysis and design of high quality systems for collimation. Electromagnetically based light source models give maximum flexibility and accuracy to investigate collimating systems. In particular in high NA focusing and collimating systems, the z-component of the fields must be taken into account. Our electromagnetic field modeling provides this information. Moreover, electromagnetic modeling allows the investigation of focusing and collimation systems for partial coherent light sources and ultra short pulsed laser beams. LightTrans’ optical engineering team will help you in all situations in which you need a more elaborate investigation or design of your focusing or collimation system.

- Coupling of laser light, here from a diode laser, into a fiber is of concern in various applications. In order to investigate the coupling efficiency one needs complete information about the electromagnetic field in the focal region. This is a typical task for which our electromagnetic modeling approach is ideal to deliver you all the information you need.
