With the proposed diffractive lens arrays, an objective with a low numerical aperture can have much higher resolution while maintaining its large field of view. Application of the diffractive lens arrays in fluorescence microscopy is presented in this work. The resolution enhancement is demonstrated by experiments with the fluorescent beads.","PeriodicalId":386109,"journal":{"name":"International Optical Design Conference","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116225015","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 have implemented an exact ray trace through a separated doublet lens considering a plane wavefront propagating along the optical axis. The analytic equation of both the caustic surface and the back focal length for separated doublet lenses are provided. Demanding that the back focal length tends to infinity, we impose the conditions to design afocal optical systems, obtaining sixth and fourth degree polynomials as a function of the radii of curvature. In order to produce an afocal achromatic optical system, we solve numerically a set of two nonlinear equations assuming two spectral lines. Therefore, we have two unknowns which are the curvature radii for both the front surface and the rear surface. The contribution of this work is to provide simple formulas for designing optical beam expander or reducer devices based on separated doublets.","PeriodicalId":386109,"journal":{"name":"International Optical Design Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125999180","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}

Thanks to a model based on effective medium theory used in conjunction with lens design software, the optical properties of custom metasurfaces within a complex system can be calculated. Compared to simple phase surfaces embedded in common lens design software, the phase shift profile given by our model is dependent on the wavelength and field of view. We thus demonstrate that those phase surfaces cannot accurately reproduce the behaviour of metasurfaces in every system. As a proof- of-concept, a hybrid refractive and metalens design was also made. The metasurface located within two refractive lenses corrects mainly the spherical aberration and allows the system to be almost diffraction-limited for the whole field of view.","PeriodicalId":386109,"journal":{"name":"International Optical Design Conference","volume":" 33","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113950374","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}

These optics require a long total track length (TTL, distance between the actual panel displaying the contents and user’s pupil) to work well, and headsets become very bulky. The so-called CLOVER is an optic, compatible with VR and video-see-through mixed reality (MR) able to work around the TTL problem by using a freeform multi-channel, light folding approach. In its simplest version, it can reduce the TTL down to a half, compared to conventional solutions, for the same FOV and angular resolution. Along with a review of the original 4-channel CLOVER, this work shows recent results of upscale versions of the optic that utilize myopia and color correction, pupil tracking and staggered surfaces to, respectively, avoid the need of prescription lenses, improve the image quality for all colors, rise the resolution (by a 20%) and reduce the size (20% TTL reduction) of the precursor.","PeriodicalId":386109,"journal":{"name":"International Optical Design Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126795743","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}

The high-precision telescope system utilizes a piezo-actuated flexural mechanism to introduce secondary mirror misalignments and generate aberrations intentionally. The induced aberrations are measured interferometrically and quantified for a grid of field points on the image plane of the telescope. For this purpose, a coma-free pivot point of the secondary mirror was simulated for isolating the binodal astigmatism field response. A simulation of binodal astigmatism was generated using a real ray trace model of the Cassegrain system and analyzed to compare to the experimental results. The experimental results were consistent with the simulations, hence experimentally validating NAT for binodal astigmatism for the first time.","PeriodicalId":386109,"journal":{"name":"International Optical Design Conference","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133344509","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}
