“…Interferometers for testing objectives are proposed by Steel (278) and Burch (39). Claussen (49) discusses the development of the piano-objective during the last two decades. The theory of this type of objective is given, and illustrated with micrographs showing results obtained.…”

“…A clear review of the latest arts is still missing. In addition, design principles were seldom discussed [8], and illustrative systematic synthesis approach cannot be found for high NA cases [9][10][11]. Last year, we have proposed a new systematic approach for microscope objective analysis and synthesis [12], which is based on 116 systems from patents.…”

In the three connected papers, a systematic analysis and synthesis approach for microscope objectives is introduced. To subtract off the hidden assumptions in the historical development of the microscope objective lenses and extract the intrinsic lens modules, a large objective database is implemented including most of the patented systems for standardised applications. Based on the systematic analysis of the database, in Part I, a general review of the development history is given. A systematic classification method is proposed with respect to the five most significant parameters. According to the review and classification, the impacts of applications, manufacture and technology considerations are systematically analysed and summarised. Details of the lens modules will be discussed in Part II, and the synthesis approach utilising the lens modules will be introduced in Part III.

“…The first surface is concave toward the object-a common configuration in microscope objectives that allows for the reduction of spherical aberration and field curvature. [20][21][22] The lens was designed for monochromatic 633 nm light but remains diffraction-limited to about a bandwidth of AE50 nm from the design wavelength. That is, at AE50 nm, the RMS polychromatic geometric spotsize is approximately the same as the Airy disk radius.…”

Abstract. We present a foveated miniature endoscopic lens implemented by amplifying the optical distortion of the lens. The resulting system provides a high-resolution region in the central field of view and low resolution in the outer fields, such that a standard imaging fiber bundle can provide both the high resolution needed to determine tissue health and the wide field of view needed to determine the location within the inspected organ. Our proof of concept device achieves 7 ∼ 8 μm resolution in the fovea and an overall field of view of 4.6 mm. Example images and videos show the foveated lens' capabilities.
