Crystalline organic compounds are of particular interest for many applications where their performance is impacted by the crystalline properties. However, investigating crystallization processes in solution remains challenging because their rapid and complex dynamics are difficult to quantify. To this end, we developed an innovative multimodal optical setup capable of in-situ measurements of dynamic processes. Our approach combines a tunable femtosecond pulsed laser and a continuous wave laser, leveraging spectrally resolved scattering and fluorescence detection to measure up to nine different optical effects: second and third harmonic scattering and their depolarization ratios, linear light scattering, multi- and one photon excitation fluorescence, optical rotation and transmission. In this study, we aim to discover the crystallization dynamics of regioregular poly(3-hexylthiophene) through anti-solvent addition. Our findings demonstrate the capability of our setup to provide valuable insights for the optimization of photonic materials.","PeriodicalId":434863,"journal":{"name":"Optical Engineering + Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114141666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a secondary objective, SPRITE will track the stability of new advanced ‘eLiF’ mirror coatings and Micro Channel Plate (MCP) detector over the mission’s lifetime as they are sensitive to molecular contamination, especially from organic compounds, silicones, as well as exposure to water vapor. As a result, a thorough cleaning procedure was created to prepare the components for flight assembly. This system contains two ovens that are able to operate independently of one another. One operates at approximately 3 torr with a nitrogen purge, while the other operates at 10-6 torr and funnels contaminants into a liquid nitrogen cold trap. Typically, parts are baked in the low-vacuum oven for three to four days before being transferred to the high-vacuum oven to bake for an additional three to four days where the liquid nitrogen and Residual Gas Analyzer (RGA) measurements are checked daily. This process allows parts to outgas in a controlled environment, rather than exposing the optics to molecular contaminants during integration and while on-orbit (throughout the mission lifetime). This paper will detail the fabrication of the custom vacuum bakeout system and the associated procedures used to bake components at high vacuum. This vacuum bakeout setup is inexpensive and sufficient to meet the contamination control needs of sensitive missions like SPRITE, within the limited budgets of CubeSat and SmallSat missions.","PeriodicalId":434863,"journal":{"name":"Optical Engineering + Applications","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129273271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This will be carried out by studying the x-ray Universe with a space-based telescope to be launched in the second half of 2030s. Several materials have been considered as overcoating candidates for the Silicon-Pore Optics (SPO) mirror plates developed for NewATHENA. Previously, carbon did not qualify as an overcoating material since it was not compatible with the manufacturing processes. However, new coatings made in the dedicated chamber for NewATHENA located at cosine Research BV, together with an improvement on the selected cleaning procedure, have shown that carbon is now compatible with the process. This work covers the characterization of the mirror coatings for NewATHENA following a complete and representative wet chemistry process. The primary focus is on the overcoating carbon layer and the hybridisation of the atomic orbitals within its constituent atoms. For the characterization we used X-Ray Reflectometry (XRR) and X-ray Photoelectron Spectroscopy (XPS) techniques. We performed θ−2θ reflectivity measurements at fixed energies of 1.487 keV and 8.048 keV, and at a fixed incident angle of 0.6° from 3.4 to 10.0 keV. We performed Angle Resolved XPS (ARXPS) measurements with an energy of 1.487 keV. We found that both techniques are in agreement showing an sp3 -content on the samples around 20%, indicating a certain level of diamond-likeness. Although it remains unclear if this is the reason for the compatibility of carbon with the manufacturing process, our work shows that the species of carbon grown in the film are able to ensure a good stability of the mirror.","PeriodicalId":434863,"journal":{"name":"Optical Engineering + Applications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129947185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a method to fabricate spacers and bond them between thin mirrors, then adjust mirror alignment by focusing ultrafast laser pulses into these spacers. We built a simple mirror stack assembly composed of two flat mirrors bonded to two spacers and wrote laser-induced modifications into these spacers. We interferometrically measured the air gap between the two mirrors after each set of laser-induced modifications. The resulting deformation in the spacers and measured tilt between flat mirrors shows that realignment can be controlled using the ultrafast laser, however there is uncertainty introduced by imperfect mirror stack assemblies. Future work will aim to achieve predictable laser-induced strain. The presented assembly procedure and laser-strain generation process serves as a potential solution to the optomechanically-limited design of current-generation x-ray telescopes.","PeriodicalId":434863,"journal":{"name":"Optical Engineering + Applications","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122743523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
