Limit of interference in optical instruments
1952A rigorous theory has been given for the limit of interference in Lummer Gehrcke plate, transmission and reflection echelons and the grating on the lines of Saha's treatment for Fabry-Perot interferometer.

For a perfect optical system as sketched in fig. 1 (which also defines the notations) the minimum distance of resolved bubbles can be written, according to the Rayleigh criterion, $$R = \frac{{1.22\lambda p}}{a} = 1.22\lambda (m + 1)(f/a)$$ (1) (λ being the wavelength of the light, we shall assume λ = 0.55 µm).

Optical Society of America Annual Meeting, 1990
Many of the unique advantages of optics stem from its almost unlimited fan-in capability. For instance, it is possible for light from 106 or more well defined regions to come together at a single optical element or even in parallel on 106 or more optical detectors, spatial light modulator pixels, etc. Is there a theoretical limit to this fan-in number?

Exploring the limits of optics
Nature Photonics, 2017At the 24th General Congress of the International Commission for Optics in Tokyo, photonics-based sensing and simulations were shown to benefit research into phenomena that span the nanometre to astronomical range.

Materials for optical limiters
Current Opinion in Solid State and Materials Science, 1999Nonlinear limiters may protect optical sensors against pulsed lasers of any wavelength. New nonlinear materials have been produced, offering increased nonlinear sensitivity and reduced visual loss. Particle suspensions, macrocyclic dyes, and two-photon absorbers are particularly promising. Issues surrounding incorporation into optical systems are under

The Limits of Optical Lithography
2009In 1979, Electronics magazine reported that stepper lithography would be a passing fancy superseded by direct-write electron beam lithography by the year 1985. It was admitted in a follow-up article, written for that same magazine in 1985, that the demise of optical lithography had been predicted prematurely and that it would take until 1994 for ...

Is there a limit to the performance of linear optical components? Suppose we asked a specific question, such as how much glass would we need to make a device that would split 32 wavelengths in the telecommunications C-band near 1.5 I¼m wavelength. Intuitively, we would probably agree that 1 I¼m3 of glass would not be enough.
