Special Issue Information
Dear Colleagues,
Freeform optics is an emerging technology that brings an evolutionary development for both imaging and non-imaging optics.
New fabrication techniques can fabricate optical surfaces with no axis of rotational symmetry, which open an expansive new space for optical systems. Particularly enabled systems include illumination systems, head-worn displays, mid- and long-wave pervasive surveillance systems, extreme ultraviolet lithography, solar concentrators, space optics, mobile displays, manufacturing, remote sensing, and medical and biosensing technologies.
However, the technology requires expertise in bringing together cross-disciplinary fields of design, simulation, fabrication, testing, and assembly into one process. Concurrent freeform optics technologies are still facing many issues, such as new representations of freeform surfaces, metrology of MSF errors for freeform surfaces, design methods for all-reflective multi-mirror unobscured freeform systems, the application of freeform optics in spectrometers, new freeform optics manufacturing technologies, additive manufacturing technologies of freeform optics, Alvarez-like lenses, molding technologies of freeform optics, and novel metrology methods of freeform optics to reduce cost.
This feature issue will highlight significant contributions in both academia and industry with regards to the evolution of freeform optical systems in design, fabrication, metrology, and novel applications, as well as artificial intelligence and machine learning techniques.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Photonics is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
