A Beam Modulation in the Multilayer Parabolic Bio-nanostructures of the Eye of the Firefly

The research found the alternative optical properties of the firefly eye from its crystalline cone. The eye of the firefly has the periodic indices of refraction and configuration of 190 parabolic layers as a one-dimensional photonic crystal on the optical axis treated ommatidium of the firefly. The paper performed anatomy of the firefly eye to […]

Thin Films MultiLayer Calculator added

https://apps.apple.com/us/app/optical-coatings/id1504155817 The app assists in the design of optical multilayer coatings. It supports 100 layers for calculation of reflectance and transmittance of the polarized light at the angle of incidence. The App can be used offline using it anywhere. The calculator program is following electromagnetic theory and transfer matrix theory: Frank J. Pedrotti, Leno S.Pedrotti, […]

Laser Physics Helps to Understand the Corona Virus Crisis

Posted on 2020-03-16 as a part of the Photonics Spotlight (available as e-mail newsletter!) Permanent link: https://www.rp-photonics.com/spotlight_2020_03_16.html Author: Dr. Rüdiger Paschotta, RP Photonics Consulting GmbH Abstract: Because laser operation involves some similar aspects as the spread of an epidemic, in particular exponential growth and threshold behavior, one can in fact develop a clearer picture of what kind of measures […]

CalcAnti2Films App Added

The app calculates the reflectance for two-layer anti-reflection at normal incidence. It shows the reflectance versus wavelength, which depends on the refractive index and film of thickness. The calculator program is following electromagnetic theory and transfer matrix theory: Frank J. Pedrotti, Leno S.Pedrotti, by Frank J.Pedrotti, Leno S.Pedrotti., [Introduction to Optics (2nd ed)], Prentice-Hall, Upper […]
