Spider Silk: The Mother Nature`s Biological Superlens
... a ratio of 2:1 [10-12]. The spider silk has a diameter in the range of 6.8µm. The surrounding medium is Isopropyl alcohol (IPA) with a refractive index of 1.377 [12] overlaid with transparent cellulose-based, pressure sensitive tape, which acts as a birefringent retardant [13] as well as allowing f ...

RAY OPTICS NOTES - RIT Center for Imaging Science
... To design optical image-forming systems, we must model the propagation of light from the object (source) to the optic, the action of the optic on the incident light distribution, and finally propagation from the optic to the sensor. The last step of conversion of the spatial (and possibly spectral) ...

the fresnel diffraction: a story of light and darkness
... the light beams diffracted by the double slits, demonstrating thereby the wave nature of light against Newton’s particle theory. Indeed, the darkness in the fringes cannot be explained by the sum of two particles but easily interpreted by vibrations out of phase. This argument was very strong. Nevert ...

Introduction: When waves encounter obstacles (or openings), they
... The area of the zone increases with increase in the wavelength of light and with increase in the distance of the point P from the wave front. As discussed in Fresnel's Assumptions the effect at a point will depend on (i) the distance of P from the wave front, (ii) the area of the zone and (iii) the ...

F-number
In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography. The number is commonly notated using a hooked f, i.e. f/N, where N is the f-number.
