    Design Lens Lost
AI Thread Summary
The discussion centers on the rediscovery of an aspheric lens design equation that was previously lost. A member located a preserved link to the Thorlabs page containing the equation, which addresses ideal shapes for lenses without spherical aberration. The updated thread now includes the correct link to access the information directly. A screencap of the formula was also shared, adhering to Fair Use guidelines. This exchange highlights the importance of preserving and sharing valuable technical resources in optical design.

Hi all,

I was interested in ideal shapes for lenses and Google popped up this very old thread:
"Mathematical shape for a lens with no spherical aberration"A member named Redbelly98 replied (<link>) with a now-broken link to a Thorlabs page that gave an aspheric lens equation.

Took a minute, but I think this is the page with that equation (on the page's "Lens Equation" tab) safely preserved on Internet Archive:
"Molded Glass Aspheric Lenses: 350 - 700 nm or 400 - 600 nm AR Coating" - Thorlabs
 
Science news on Phys.org
I edited a screencap of the formula (for compactness)
from the ThorLabs web-page, by virtue of Fair Use
bcoz U.S.Code Title 17, Section 107, blah blah blah

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
