“…While low-energy particles do not affect shielded components and systems, they can be detrimental to unprotected components directly exposed to radiation, such as mirrors, filters, and windows. For this reason, the study of the damage induced by low-energy particles on optical materials, thin films, and coatings in the space environment is pivotal for the realization and optimization of scientific instrumentation, navigation sensors, and solar panels. − …”

The present work reports a systematic study of the potential degradation of metals and dielectric thin films in different space environments. The mono-and bilayers selected are made of materials commonly used for the realization of optical components, such as reflective mirrors or building blocks of interferential filters. More than 400 samples were fabricated and irradiated with protons at different energies on ground-based facilities. The fluences were selected as a result of simulations of the doses delivered within a long-term space mission considering different orbits (Sun close, Jovian, and Geostationary orbits). In order to stress the samples at different depths and layer interfaces, experiments were carried out with a range of proton energies within 1 and 10 MeV values. An estimate of a safe maximum fluence has been provided for each type of sample at each energy. The damage mechanism, when present, has been investigated with different optical and structural techniques.

“…These coatings are particularly beneficial in optical devices, such as lenses, mirrors, and displays, where reflections can cause glare, reduce contrast, and distort the image quality [ 1 ]. AR coatings are typically designed to minimize the reflection at a specific wavelength [ 2 ], several wavelengths [ 3 ], or over a range of wavelengths [ 4 , 5 ], depending on the application. Physical vapor deposition (PVD) techniques, such as electron beam evaporation, ion beam sputtering, magnetron sputtering, etc., are the most widely used methods for fabricating AR coatings, offering numerous advantages, including high deposition rates, good film uniformity, and the deposition of high-quality optical coatings with high laser-induced damage thresholds [ 6 , 7 , 8 ].…”

Anti-Reflective Coatings Produced via Atomic Layer Deposition for Hybrid Polymer 3D Micro-Optics

The increasing demand for optics quality requires the lowest optical power loss, which can occur from unwanted reflections. Laser direct writing (LDW) allows for the fabrication of complex structures, which is particularly advantageous in micro-optic applications. This research demonstrates the possibility of forming an anti-reflective coating on hybrid polymer micro-lenses fabricated by employing LDW without changing their geometry. Such coating deposited via atomic layer deposition (ALD) decreased the reflection from 3.3% to 0.1% at a wavelength of 633 nm for one surface of hybrid organic–inorganic SZ2080™ material. This research validates the compatibility of ALD with LDW 3D multiphoton lithography synergistically, expanding its applications on optical grade sub-100 μm scale micro-optics.
