Exact Design of Aplanatic Microscope Objectives consisting of Two Conic Mirrors.
TLDR
The necessary equations are derived for the design of aplanatic microscope objectives consisting of two mirrors, one concave and the other convex, and the first-order parameters are calculated along with the conic constants of the mirrors, determined by means of an exact analysis.Abstract:

A review of high-grade imaging of diatoms and radiolarians in light microscopy optical- and software-based techniques
TL;DR: Several optical- and software-based techniques for light microscopy are presented, which can be suggested as suitable means for the enhancement of image quality in observations and photomicrography of 3D specimens, especially diatoms and radiolarians.

Luminance Contrast — a New Visible Light Technique for Examining Transparent Specimens
TL;DR: The intensity of contrast is determined by the specification of the phase ring within the phase contrast lens and dependent on the specific phase differences between the specimen and its surrounding medium as mentioned in this paper, i.e., the difference in brightness between the background and specimen, is constant and not variable.

Luminance contrast, a new illumination technique in light microscopy: Optical basics, practical evaluations, further developments
TL;DR: Luminance contrast as mentioned in this paper is a new illumination technique in light microscopy recently developed by the author, which leads to extraordinary contrast effects, enhanced focal depth and supramicroscopic resolution when transparent stained or unstained specimens are examined.

Mirror lenses in light microscopy--theoretical considerations and practical implications.
Jörg Piper,Jörg Piper +1 more
TL;DR: Supramicroscopic image qualities could be expected if mirror lenses were produced based on the optimized manufacturing techniques available nowadays, based on theoretical consideration, and intensive practical tests carried out with several mirror lenses constructed in various optical designs.

Optical Design with Aspheric Surfaces and Exact Ray Tracing: An Analytic Method
TL;DR: In this paper, a method to compensate the spherical aberration for any optical system and any object position is presented, where the aspheric coefficients are calculated by solving a system of first grade equations.

A new series of microscope objectives: I. Catadioptric Newtonian systems
David S Grey,Paul H. Lee +1 more
TL;DR: A study of catadioptric objectives limited to spherical surfaces is initiated, as it does not seem possible to achieve freedom from chromatic aberrations over this interval with purely refractive objectives of large numerical apertures.

A New Series of Microscope Objectives: II. Preliminary Investigation of Catadioptric Schwarzschild Systems*
TL;DR: This paper presents a preliminary study of combining the Schwarzschild pair of mirrors with lenses of fused quartz and fluorite to obtain an ultraviolet microscope objective and it is found that the catadioptric Schwarzschild objective is superior to the catadoptric Newtonian objectives.

Computed Aberrations of Spherical Schwarzschild Reflecting Microscope Objectives
TL;DR: In this article, it was shown that for a microscope objective with small central obstruction of aperture and small wavefront deformation, the central amplitude becomes excessive unless the object field is restricted to an extraordinarily small diameter.

A relation between the conic constants of two mirror telescopes
TL;DR: In this paper, the authors analyzed the two mirrors conic constants of a reflecting telescope design for which the spherical aberration is exactly corrected by means of a formula for a secondary mirror conic constant, as function of other telescope parameters.
