In optical system design, light is the currency you spend to get meaningful results, but etendue is your spending limit. Many system designers hit a technical wall where simply trying to deposit more laser power or buy a faster camera no longer yields results. This stagnation happens because the system's etendue has already capped how much information can actually be transferred. To truly overcome these bottlenecks, we must look beyond individual components and consider the etendue conservation of the entire optical train.

The design of illumination optics for fluorescence-based systems has traditionally been defined by a frustrating compromise: speed versus sensitivity. If you’ve ever had to choose between the high intensity of a pinpoint laser and the rapid scanning speed of a wide-field beam, you’ve experienced the inherent limitations of traditional illumination design. But what if you didn’t have to choose?
