These days, nothing lasts very long, and things often change for the better, but there are sure things in our community, such as this annual event, which has been going on for 25 years. The first edition in 2000 of the currentdevelopments in lensdesign and optical Systems engineering Conference took place during International Symposium on optical science and technology, 30 July - 4 August 2000 in San Diego. Over 45 oral presentations and ten posters were presented. The chairs were Robert E. Fischer, Warren J. Smith, R. Barry Johnson, and William H. Swantner. The proceeding was numbered 4093 and 24 years later the number is 12666 (2023). This paper looks back on the great moments of our conference, its speakers, the subjects that have come and gone, and those that have remained.
The proceedings contain 19 papers. The topics discussed include: athermalizing mounted doublets with ALLvAR alloys;using off-the-shelf components in the design of curved compound eye camera systems;Uv-replicated monol...

Our study presents recent progress in modelling and performing lensopticaldesign with metasurfaces. We developed semi-analytical models that recover the output phase, polarization, dispersion and group delay of various nanostructures. This enables the mixing of different nanostructures to obtain a target dispersion profile an interesting application of the model. These models can readily be implemented within opticaldesign software such as Zemax and use the built-in optimization of opticaldesign processes while avoiding time-consuming electrodynamics computation. We also introduce the metasurfaces to the analytical lensdesign framework. This enables us to analytically compute the phase profile of freeform metasurface doublet concerning particular ray conditions such as the Abbe Sine condition as we presented here.

A luminaire designed for tunnel lighting is proposed, featuring the ability to adjust the ratio between counter-beam and pro-beam lighting based on different contexts. This allows the luminaire to achieve the optimal lighting mode for the conditions within the tunnel at that time. When both side LEDs are activated, it operates in symmetric lighting mode. When a single-side LED is activated, it switches to either counter-beam or pro-beam lighting mode. The advantage of this luminaire lies in the use of a single freeform secondary lens and LEDs, making installation simpler. It ensures driver safety and is more energy-efficient than traditional tunnel lights.

The fabrication of curved compound eye camera systems is usually complex since it can involve multiple nonstandard components to achieve the desired effect. In this paper we aim to provide a close alternative to these custom optical elements using off the shelf components or to provide a framework to design these systems using standard fabrication techniques. We will first demonstrate how lens distortion can be leveraged to optically bend a standard planar microlens array, and how this bending correlates to a curved microlens array. We will then show lab results of curved compound eye camera made using an off-the-shelf fisheye lens and a standard microlens array and how the equivalent curved microlens array system reproduces image in the real world and provide a comparison using image simulation from an opticaldesign software and a scene recorded using a neural radiance field.

Liquid Mirror Telescopes have been shown to be a credible alternative to traditional telescopes for building low-cost observatories. Previous LMTs were based on the rotation of a pool of mercury which, from the rotation, takes the shape of a parabola. However, they cannot be tilted as traditional telescopes to observe at fields away from the zenith. In the context of the DARPA Zenith program, we present a telescope concept where a magnetic fluid is shaped to a parabolic surface by combining wetting effects and magnetic fields which allow the telescope to be tilted. We also show that the off-axis optical aberrations of the telescope, when observing off-axis, can be cancelled by a surface correction of the parabolic liquid surface by adding a correction to the already applied magnetic field that shapes the mirror surface. In this approach, the scientific instruments are located at the focal plane and designed to track the beam as the field changes.
