Mertz","doi":"10.1364/ild.1990.lwb5","DOIUrl":"https://doi.org/10.1364/ild.1990.lwb5","url":null,"abstract":"Two sufficient conditions for good unit-magnification imagery are that the optical system be concentric and retroreflecting. These conditions are satisfied by both the Dyson1 and the Offner2 systems. Schmidt corrector plates as shown in figure 1 are seen to extend the field as we note that the Offner system is a Schmidt telescope with image and pupil planes interchanged. Moving the corrector’s neutral zone outward leads to whispering gallery systems as shown in figure 2, where again the Schmidt plates can widen the annular field. In analogy with the successful inclusion of a diffraction grating in the Dyson system3, it is speculated that holographic gratings could also be used on the mirrors marked G in the systems of figure 2 to obtain stigmatic flat field spectrogaphs. Figure 3 shows a folded version of figure 2A. Figure 4 shows how to evolve an ellipsoidal confocal aplanatic system to a Czerny-Turner system along the style of an Offner spectrograph.","PeriodicalId":215557,"journal":{"name":"International Lens Design","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127153302","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 National Weather Services (NWS) have stated an ultimate goal for temperature sounding of 1 degree accuracy and 1 km vertical resolution throughout the troposphere. To approach this goal next generation temperature sounders must have increased spectral coverage and increased spectral resolution. Extensive simulations indicate that a temperature sounder with spectral resolving power (λ/Δλ) of 1200 and wavelength coverage from 3.4 - 17 μm will significantly improve the rms temperature retrieval accuracy. The Atmospheric Infrared Sounder (AIRS) for the Earth Observing System (Eos) has been designed to meet these requirements.","PeriodicalId":215557,"journal":{"name":"International Lens Design","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132557310","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}

Many refractive designs exist for the visible (0.4μm to 0.7μm) as well as medium-wave infrared, MWIR, (3.0μm to 5.0μm) applications. However, design solutions that bridge the gap between these two spectral regions are not very common. Recent work at SBRC has uncovered several solutions with reduced secondary color in the 1.0μm to 3.0μm band and that even extend from 0.5μm to 5.0μm.","PeriodicalId":215557,"journal":{"name":"International Lens Design","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129883642","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}
