Optiland – Can you use an open-source tool for optical design?
By Madeleine Åkeson| Have you ever wanted to make, analyze or adjust an optical design, but did not have access to a license for an optical design software such as Zemax? Or, have
Light pollution

The Optics Of Rainbows
By Gustav Strömqvist | Rainbows are a beautiful physical phenomenon, forming as the result of how the sunlight refracts and reflects inside droplets of water before reaching
Lightguides – shape and performance – part 2
By Billy Kaldvee | In the last post we recommended to keep the distance between the LED and the light guide ten times smaller than the light guide diameter. To demonstrate why this
Lightguides – shape and performance – part 1
By Billy Kaldvee | Have you ever done a mechanical design of a light guide without doing any optical simulations and wondered why the result looked as something you did not expect?
Etendue and Optical Invariants
By Olov von Hofsten and Simon Olin | “The possibilities of optics are endless” – you may have heard things like this and it sounds great and wonderful. Unfortunately it is no
The Perfect LiDAR – does it exist?
By Olov von Hofsten | As a consultant, I have often been approached by unrealistic requirements from customers, and the LiDAR business is particularly prone to this. Perhaps becaus
Simulating Luminance in Zemax
By Olov von Hofsten | Luminance is arguably the most important component to analyze when evaluating a lighting design since it answer the fundamental question, “What will it look
7 Best Zemax Tricks and Tips
By Olov von Hofsten | At Eclipse we use Zemax a lot, everyday actually. But although we know the optics necessary to make optimal optical designs, knowing a software’s hidden sho
