Abstract
This study explores the next step in customised measurement instruments by reconsidering the assumption that confocal measurement devices cannot be manufactured using consumer-grade equipment. Historically, these devices have required specialised manufacturing due to complex optical components like ground glass lenses, which are expensive, bulky, and difficult to customise.
The key challenge—optimising light propagation, focusing, and image processing—has been addressed with simple, innovative solutions, including the development of confocal Fresnel lenses. These lenses, characterised by concentric grooves, offer a lightweight, cost-effective alternative to traditional lenses while maintaining strong optical performance.
Modelling and testing have demonstrated the Fresnel lens’s advantages, particularly in reducing weight, cost, and simplifying integration. While it may not outperform traditional lenses in all high-precision applications, its lower production costs and adaptability make it ideal for systems with size and budget constraints. This combination of benefits and limitations expands its practical use across various fields, offering a balance between performance and efficiency.
